Motor Termination Units

Since the rise time of IGBTs are in the range of a few tens of nanoseconds (between 50ns-200ns), even short cables between PWM motor drives and motors can cause voltage doubling at the motor terminals, due to Travelling Wave Phenomenon as in transmission lines.

If necessary precautions are not sufficiently taken, the insulation of motor windings are prone to failure due to high voltage spikes. RC Type Output Filter Modules reduce these high voltage spikes and protect motors by connecting to stator terminals.
