Tolomatic: Electric rod actuator cleans up after hydraulics

Hydraulic cylinders are well-known linear motion workhorses in industrial machinery.   They’re reliable, familiar, capable of high force, and affordable, but they’re not without disadvantages. The leading ones are fluid leaks, large footprint (with hydraulic power unit or HPU), cumbersome changeovers due to lack of programmability, and high maintenance costs.

The introduction of electric high force linear actuators means machine designers now have a choice. An electric rod actuator can replace a hydraulic cylinder and eliminate the need to clean up leaks.

For a thorough look at hydraulic versus electric actuators, download our white paper.

A mess to clean up

A manufacturer was using hydraulic cylinders to press, form, and package face powder and other cosmetics. Problems with position control, speed, accuracy, and repeatability were rampant throughout the process. The machines needed to be cleaned constantly because hydraulic fluid leaked from hoses and pumps. That cleaning meant costly downtime and spoiled product. Even more downtime came when changing to different cosmetic lines or product mixtures because changeover was a time-consuming, manual operation.  Also, a problem: the hydraulic system’s HPU with its main pump and reservoir took up valuable floor space in the production area.

 

The manufacturer wanted an electric actuation system to eliminate the wasted space, costly downtime, and product quality fluctuations caused by the hydraulic system.

A clean, electric solution

Designers chose an RSA50 electric rod actuator with reverse parallel motor mount to replace the hydraulic cylinder. The RSA50 supplies significant force at faster speed and with better accuracy and repeatability than the hydraulic system it replaces. The servo motor/drive of the new actuation system stores each product line’s requirements so they’re readily available. Operators now have a flexible controls platform and can make changes on the fly during production.

The RSA eliminates messy hydraulic fluids, hoses, and pumps, and it frees valuable floor space by eliminating the large HPU. Also, the cost of the RSA solution was within budget, and ROI was significant – daily output doubled and product quality increased.

 

RSA electric rod actuator series

The RSA/RSM line of electric rod actuators includes

  • RSA-ST –– low-to-medium thrust capacity actuators. RSA-ST electric rod actuators deliver accurate, medium force performance making them ideal for replacing pneumatic cylinders. High thrust bearings and internal bumpers deliver heavy duty performance. A rigid, strong aluminum housing allows for easy mounting of switches and sensors.
  • RSA/RSM-HT — heavy duty, high force electric rod actuators for tough environments. RSA/RSM-HT actuators accommodate larger motors and deliver high force with excellent accuracy. These high force linear actuators can be ordered with either ball or roller screws and have enhanced high thrust bearings and heavy duty internal bumpers.

LUTZE DRIVEFLEX® Cable for VFD and Motor Applications

Variable frequency drive (VFD) cables have distinct advantages over traditional cables when used in drive and motor applications. When installed properly, VFD cables reduce cross coupling between drives and the shield contains and drains the electrical noise created by the drive. Their noise mitigation helps with the proper function of adjacent control systems and they help to reduce motor shaft voltage and bearing currents.

LUTZE DRIVEFLEX® cables are designed to cope with the power distortions in VFD applications. They offer superior electrical values for VFD or servo applications and are UL listed type “Flexible VFD Servo Cable, Flexible Motor Supply Cable” to comply with codes and standards regarding electrical wiring of VFDs. DRIVEFLEX® XLPE insulation has very low capacitance, high impedance and high voltage breakthrough resistance.  DRIVEFLEX® cables are safer and more efficient compared with traditional PVC/Nylon power tray cables or THHN wires in conduit.

LUTZE has recently expanded their DRIVEFLEX® line to include series A106 and A107, which are smaller diameter, general purpose series drive cables. Which type you use will depend on your specific project and requirements.

  • A106 series is great for most VFD applications and motors up to 40 HP and features a small outer diameter (OD) for easy routing and use in conduit.
  • A107 series cable is similar to the A106, but includes one shielded pair for brake or control signals.

Don’t trust your VFD and motor operations to tray cable or THHN.  Interested in learning more about DRIVEFLEX® or ordering it for your next project? Give your French Gerleman Account Manager a call today!

Copper vs. Aluminum Wire – Applications and Considerations

The wire and cable industry uses a variety of metal conductors, but the two most common are copper and aluminum.  Because each metal type has unique properties, they are best suited for different applications or purposes.

Copper Wire

The most popular conductor used in commercial, industrial and residential construction is copper.  Due to its elemental makeup, copper is an excellent, relatively low-cost conductor (in comparison to gold and silver which are both excellent conductors).

Copper has many features and benefits:  in addition to its common acceptance in most applications, it has high tensile strength and higher current carrying capacity by volume, which means the conductors are typically smaller.  Smaller conductors can be of benefit when working in tight spaces and a primary reason copper is the preferred material when wiring branch applications like to a switch or receptacle.

Most metals corrode which can be detrimental to the efficacy of an electrical system.  While steps should be taken to prevent oxidation of conductors, it should be noted that copper oxidation is semi-conductive.

Copper costs significantly more than aluminum, so when moving large amounts of power is necessary, copper may be cost prohibitive.  Copper is also stiffer and heavier than equivalent ampacity aluminum conductors making it difficult to work with in larger runs.

Aluminum Wire

Aluminum wire has been around for a long time.  Primarily used for utility applications, aluminum is now being used more and more in feeder applications in large scale commercial, industrial and residential applications.  You likely have aluminum coming into your house to your main breaker panel.  Aluminum is a good conductor; however, there are things that must be considered before applying this 21st century metal.

A larger volume of aluminum is necessary to conduct the same electricity as copper, so typically you must upsize your conductor two sizes to accommodate the same circuit ampacity, e.g., substitute a 750 MCM aluminum for a 500 MCM copper.  Download General Cable’s Ampacity Calculator from their app page to help with proper sizing.

Aluminum is very light.  Even though the conductors are bigger they will likely weigh less than the equivalent ampacity copper conductor.  Additionally, the aluminum conductors will have a larger outer diameter due to the increase in size although this is mediated using compact stranding which reduces the air gap in between the strands.  Still, the larger conductors may create the need to upsize conduit.  Aluminum Wire is also “annealed” making it much more flexible than standard copper conductors and much harder to break due to mechanical wear.

Aluminum expands and contracts at a different rate than copper – each metal has a different coefficient of expansion.   Steps must be taken to prevent issues of creep (the movement of metal at connection points in the system while under electrical/thermal cycling) from occurring.  In today’s electrical world, this is commonly achieved by using dual rated lugs provided by the manufacturer of the gear you purchase.

Earlier in this article, we noted that copper oxide is semi-conductive, but aluminum oxide is an insulator.  It is standard practice to use an oxide inhibiting grease when making a connection at any point in your electrical system when there is the presence of an oxide accelerant (moisture or other element).

Return on investment (ROI) is very important to companies today.  Thus, the most obvious advantage in selecting aluminum wire is the its lower material price.  Aluminum is used in everything today, from packaging to airplane bodies and is the most plentiful ore found on the planet and as such the supply is high and the cost associated with it is low and very stable.  When employed to distribute power it is a very cost effective alternative.

Summary

In the end, both copper and aluminum are popular wire materials for commercial, industrial and residential projects.  The appropriate wire solution will depend on the project, situation, location, budget, code compliance and safety requirements.

If you have a question please reach out to the professionals here at French Gerleman:  coupled with our partner in both aluminum and copper wire, General Cable, we can help you with an answer.  General Cable is a 100+ year-old U.S. manufacturer whose wire products are recognized for their reliable performance, durability and safety.  Its products can be found in many high-profile projects throughout North America.

French Gerleman stocks a wide range of copper and aluminum wire sizes and colors in 500, 1,000 or 2,500 foot rolls or cut to length. Pulling heads are also available for most wire sizes.  In addition to wire, French Gerleman offers a variety of wire management solutions from transport to payout to save you time, money and materials.  To learn more, give your French Gerleman account manager a call today!

Product Spotlight: Panduit VeriSafe Absence of Voltage Tester

This new product from Panduit is a game-changer in the industry! The Panduit VeriSafe Absence of Voltage Tester automates the voltage verification process for control panels to reduce the risk of exposure to electrical hazards for improved worker safety. VeriSafe conducts the same test procedures required by NFPA 70E to verify that equipment is electrically safe for servicing. Fifty-five percent of electricians and technical personnel experienced a voltage testing injury or near miss with handheld testers.[1] That’s when Panduit decided there had to be a better way and created the VeriSafe.

What is the significance of verifying the absence of voltage? There were 24,000 electrical injuries in US workplaces from 2003 to 2012. Thirty-five percent of those injuries are due to contact with wiring, transformers or other electrical components![2] The leading cause of those injuries are from performing work without turning off power and verifying a de-energized condition. This is why verifying the absence of voltage is a critical task that is part of almost every job that includes electrical hazards.

VeriSafe is a tester, not just an indicator. It can verify the absence of phase-to-phase and phase-to-ground AC and DC voltage up to 600V circuits. The automated test sequence helps reduce operator error. It uses active visual indicators that convey the status of the voltage inside electrical equipment and panels before it accessed, therefore reducing exposure to electrical hazards and protecting workers.

In just a few seconds, with just the touch of a button, the VeriSafe Absence of Voltage Tester runs several tests: test the tester, verify installation, check for voltage, verify installation and then retest the tester.

There are three components to the VeriSafe: the indicator module, the isolation module and the AVT system cable. The indicator module serves as the user interface is typically installed in the door of the electrical panel. It is designed to keep dangerous voltage away from the user. With the push of a button, it initiates the test process and provides visual indication, making the process simple, quick and safe. The isolation module is located inside the panel with a sensor that leads to the power conductors inside the panel.

To start, you will push the button to begin the test. A flashing yellow LED indicates that a test is in progress. A solid yellow LED after the test indicates the absence of voltage could not be confirmed. Red LEDs indicate presence of AC voltage and green LED confirms the absence of voltage.

VeriSafe is ideal for:

  • Equipment with a single source of incoming power
  • High risk associated with access, including frequently accessed equipment and high incident energy
  • Remote or difficult to access locations
  • Sites with temporary or intermittent power
  • Equipment with stored electrical energy
  • Equipment frequently serviced by third-party technicians

Panduit is the ONLY manufacturer who provides active testing to confirm de-energized voltage and verifies installation. They’re also the only manufacturer with safety functions that meet IEC 61508 (SIL 3) and meets the requirements for installed testers NFPA 70E-2018 120.5 (7) Exception 1.

If you’re interested in learning more or seeing the VeriSafe in action, here is a great video from Panduit showcasing the features of VeriSafe and how it can help reduce the risk of exposure to electrical hazards.

Advantages of Bonitron Regenerative Braking Solutions

In almost every industry, the old saying “time is money” stands true. This saying is no more true than in the world of Industrial Automation. Processes that require frequent stops or continuous braking create a harsh environment for variable frequency drives (VFDs), causing overvoltage faults that stop production.

Integrators are forced to sacrifice valuable time for functionality to create a system that operates properly. Bonitron Line Regeneration models are designed to provide continuous energy regeneration, giving the integrator extreme flexibility to push your process as fast as possible. This increases each line’s production by allowing the customer to stop as fast and as often as you want with no process downtime.

To size our regenerative solution, take the horsepower of your VFD and match it to the horsepower of one of our Line Regen models listed below.

The time it takes to complete your process determines the amount of profit made. When variable speed drive systems are required to brake, excess energy is generated that must be removed or the drive system can lose control of the process due to an overvoltage fault.

Bonitron’s Line Regeneration modules and Regenerative DC Bus Power Supplies give you the ability to expand the braking capabilities of your standard 6-pulse VFDs. Bonitron Line Regen models replace the traditional braking transistor and resistor option.

Instead of dissipating braking energy as heat in a resistor, Line Regen solutions return this energy to the power grid. This reduces demand from the utility, which equates to ample energy savings. Bonitron Regenerative solutions are delivered ready to install with no programming or extra components needed. Access to the VFDs DC terminals and a return 3-phase connection to the AC line are the only installation requirements.  It automatically synchronizes to the frequency of the incoming power line, allowing automatic adaptation to 50Hz or 60Hz. Being efficient and small enough to be integrated into the drive cabinet, eliminates excess resistor wiring, panel space and cooling costs.

Most panels contain multiple VFDs. Each VFD requires their own set of required components: reactor, fusing, breaker and conduit. Implementing the use of a common DC bus system removes the need of components for each individual VFD such as AC breakers, AC fusing, reactor and AC conduit. Removal of these components results in extreme reduction in costs, watts loss, installation time and panel space.

Bonitron’s Regenerative Power Supply rectifies the AC line, supplying DC power to operate VFDs. During a braking event, as the DC bus rises above the AC line peak, the Regenerative Power Supply also redirects current from the DC bus into the AC line to limit the rise in bus voltage and prevent overvoltage faults.

Utilize the Regenerative Power Supply to create a common DC Bus connection that drastically reduces the cost of the panel. To size properly simply add the horsepower of all VFDs to be connected to the common bus and apply a Regenerative Power Supply that rated to the cumulative horsepower.  Use Bonitron’s Regen Cost Savings Calculator to estimate your annual cost savings.
