What goes inside the equipment is as important, or even more important, than the shiny exteriors and graphic user interfaces on the outside.

Sine Wave filters eliminate premature motor damage caused by over voltages, cable ringing, motor overheating, and eddy current losses caused by variable frequency drives (VFD). 

AEGIS High-Frequency Ground Straps ensure a low-impedance path to ground for the high-frequency currents generated by variable frequency drive (VFD) motors and systems. 

Equipped with highly advanced control capabilities to ensure processes run exactly as intended, the Vacon 100 X decentralized drive solution supports induction and permanent magnet motors up to 50 hp (37 kW). 

Even though these systems can cost significantly more than non-inverter ASHPs, manufacturers note their higher price tags are more than offset by significantly higher efficiencies.

The U.S. Department of Energy (DOE) has announced up to $20 million in available funding to spur the development of high-speed industrial motors and drives, using high power-density designs and integrated power electronics to increase efficiency.

Remember, when wiring motors for a certain voltage, the service technician must always refer to the motor manufacturer’s literature and numbering scheme before wiring the motor for the desired voltage or damage to the motor’s windings may occur.

Nidec Motor Corp. (NMC) unveiled a brushless permanent magnet (BPM) electronically commutated (EC) pump motor with an integrated variable frequency drive (VFD) and user interface. 

The ECOSine® Active 30/50/100A is a harmonic filter that provides harmonic compensation in real-time. 

The Model MSEM is a fully programmable energy management motor starter can be specifically adapted to a user’s needs.
