REO is an original manufacturer of high quality power equipment, including electronic controllers, components and electrical regulators.
Sinusoidal filters are used for overcoming numerous problems associated with long cable runs betwen an inverter drive and a motor. The filter reduces dV/dt with associated peak voltages and currents, to a benign level. The asymmetric voltage and current wave-forms produced by pulse width modulation, are converted back almost to a pure sine wave, which helps to reduce RFI and often removes the need for a screened cable. There are also motor noise, temperature and mechanical stress reduction benefits from using a sinusoidal filter
