MH&W International Corp. is an industry leader in nanocrystalline components and innovative products for power conversion and filtering applications. Among our product offerings, we deliver solutions for protecting your motor system components from the damaging currents released by VFD systems.

VFD-driven motors have applications throughout diverse industries. Whether they’re powering HVAC units for industrial facilities, pumps for water treatment, or turbines for energy production, VFD motors’ dependability and proper functionality are critical. A damaged or defective bearing in a motor can cause a motor to fail, requiring removal and repair.

To prevent these issues and the expensive, unscheduled system downtime that follows, the team at MH&W has developed Nanotech CMC and DMC. These products protect not only bearings but entire systems by minimizing motor heating, damage to bearings and insulation, and winding overheating. They stop current from passing through ground systems and back to the VFD or other sensitive devices. Our Nanotech CMC and DMC products went through years of testing, and our customers confirm that they deliver many benefits, including:

  • Extended system protection
  • Decreased interference on sensors, gauges, computer monitors, metal detectors, and other sensitive electronics
  • Reduced system and manufacturing errors as well as unplanned system shutdowns
  • Resolved communication problems with Ethernet
  • No more flickering in VFD motor control-affected LED lighting

If you’re experiencing issues with your VFD-controlled motor systems, we have a solution that will reduce motor bearing damage and extend the life of your equipment.

VFD Manufacturers

VFD Manufacturers

To produce efficient, reliable, high-quality drives, VFD manufacturers depend on innovative solutions. At MH&W, we offer products like our Nanotech CMC and DMC to protect VFD motor systems during their service life, strengthening performance and protecting insulation and bearings. OEM VFD manufacturers worldwide use our products to create lasting solutions for their end users.

Energy

Energy (Renewable and Non-Renewable)

Wind farms, solar farms, nuclear plants, and geothermal facilities are just some examples of renewable energy sectors that use VFD-run motors for things like cooling towers and turbines. As renewable and alternative energy are newer energy sources, their production and supply must run smoothly and without disruption so that more businesses and the public will be comfortable adopting these sustainable options. VFD’s create damaging currents that will cause lubrication breakdown and electrical discharge machining (EDM) damage in the motor bearing, and electromagnetic interference which affects control signals, encoder feedback, communication links for programmable logic controllers, Remote I/O, metal detectors, pump monitors, and other types of sensors including, ultrasonic sensors, bar code/vision systems, weight, and temperature sensors. Unscheduled system outages are costly and preventing disruptions in the energy industry is crucial for consistent energy supply to the public. MH&W provides VFD motor system protection to lessen maintenance and repair needs.

HVAC

Hospital, Industrial, Commercial, and Office Building HVAC

HVAC systems provide comfortable working environments in hospitals, schools, office and commercial buildings, and industrial workplaces alike. Many of these systems are powered by VFD-driven motors, which must operate reliably for seamless heating and cooling. Optimally functioning VFD drives decrease an HVAC system’s energy consumption and save on electricity costs. VFD’s create damaging currents that will cause lubrication breakdown and electrical discharge machining (EDM) damage in the motor bearing, and electromagnetic interference which affects control signals, encoder feedback, communication links for programmable logic controllers, Remote I/O, metal detectors, pump monitors, and other types of sensors including, ultrasonic sensors, bar code/vision systems, weight, and temperature sensors. Our Nanotech CMC and DMC products protect bearings and systems from expensive damage to ensure functioning VFDs and reliable, energy-efficient HVAC systems.

Pumps and Fans

Pumps and Fans

In pump and fan motors, VFDs offer efficient performance and energy savings while adjusting speeds. VFD’s create damaging currents that will cause lubrication breakdown and electrical discharge machining (EDM) damage in the motor bearing, and electromagnetic interference which affects control signals, encoder feedback, communication links for programmable logic controllers, Remote I/O, metal detectors, pump monitors, and other types of sensors including, ultrasonic sensors, bar code/vision systems, weight, and temperature sensors. Our solutions will reliably extend the life of your VFD-driven motors, setting you up for optimal equipment performance no matter how complex the application.

Pulp & Paper Processing

Pulp & Paper Processing

This industry uses VFD-driven motors for board and paper equipment, machinery for processing pulp, and more. VFDs allow you to reliably manage torque and speed in motors for such paper processing applications, giving you the ability to optimize your processes. Along with the added efficiency, you have the side benefit of consuming less energy for reduced costs.

VFD’s create damaging currents that will cause lubrication breakdown and electrical discharge machining (EDM) damage in the motor bearing, and electromagnetic interference which affects control signals, encoder feedback, communication links for programmable logic controllers, Remote I/O, metal detectors, pump monitors, and other types of sensors including, ultrasonic sensors, bar code/vision systems, weight, and temperature sensors.

Food Processing

Food Processing

The food and beverage industry uses electric motors to power many types of equipment. Conveyor systems, pumps, refrigeration compressors, and more must operate without fail to prevent not only unscheduled system downtime but the spoilage of consumable goods, both of which can lead to significant financial losses.

VFD’s create damaging currents that will cause lubrication breakdown and electrical discharge machining (EDM) damage in the motor bearing, and electromagnetic interference which affects control signals, encoder feedback, communication links for programmable logic controllers, Remote I/O, metal detectors, pump monitors, and other types of sensors including, ultrasonic sensors, bar code/vision systems, weight, and temperature sensors.

MH&W brings enhanced reliability to food processing operations by reducing VFD-driven motor damage for reduced repairs and standstill periods.

Agriculture and Dairy Farming

Agriculture and Dairy Farming

Before incorporating VFDs, oversized agricultural systems ran inefficiently with pumps that couldn’t optimize operations. Pumping water for irrigation applications was highly expensive, allowing farmers to keep less of their profits. However, farming equipment and irrigation systems continue to evolve, keeping pace with new technological developments. With a VFD motor, pump pressure and flow are easier to control, and agricultural systems no longer require a series of pumps, throttling valves, or bypass lines.

VFD’s create damaging currents that will cause lubrication breakdown and electrical discharge machining (EDM) damage in the motor bearing, and electromagnetic interference which affects control signals, encoder feedback, communication links for programmable logic controllers, Remote I/O, metal detectors, pump monitors, and other types of sensors including, ultrasonic sensors, bar code/vision systems, weight, and temperature sensors.

Water Treatment

Water Treatment

Reliable motors are an integral part of the pumping systems within water treatment plants. In these applications, motor failure is costly not only in terms of making repairs but also in the potential for public endangerment. When electrical damage causes a bearing to fail prematurely, this can result in the failure of your motor. Any type of motor can incur such damage, but VFD-driven motors experience it more frequently.

VFD’s create damaging currents that will cause lubrication breakdown and electrical discharge machining (EDM) damage in the motor bearing, and electromagnetic interference which affects control signals, encoder feedback, communication links for programmable logic controllers, Remote I/O, metal detectors, pump monitors, and other types of sensors including, ultrasonic sensors, bar code/vision systems, weight, and temperature sensors.

MH&W brings enhanced reliability to water treatment operations by reducing VFD-driven motor damage for reduced repairs and standstill periods.

If these currents aren’t “absorbed” the effect will be lubrication breakdown and electrical discharge.
