Sine Wave Filter Prevents VFD Motor Damage

Description

These Sine Wave filters eliminate premature motor damage caused by high dv/dt, overvoltages, cable ringing, motor overheating and eddy current losses caused by Variable Frequency Drives (VFD) and elongate service life of expensive high speed motors. By eliminating circulating bearing currents they can also improve bearing life.

Typical applications include high-speed spindles, textile machinery, lasers, military appliances (400Hz), HVAC applications, pumps, ventilators, conveyors, compressors, elevators, cranes, step-up transformers, motor drives with multiple motors, and motor drives with long motor cables.
