Motor Protection

Protect motors from harmful overvoltage and dV/dt spikes

Enerdoor’s motor protection series protects motors from harmful overvoltage and dV/dt spikes generated by the drive’s output, ideal for applications with variable frequency drives, servo drives and long cable applications. This series includes common mode and differential mode inductances, sine wave filters and snubbers designed to work with various frequency switches, output frequencies and applications.  The sine wave filter series reduces the pulse wave modulation (PWM) effect, converts the PWM to a sine wave and reduces dV/dt.

The FIN915SF model is used with fundamental frequencies up to 2kHz. The high frequency inductance FIN960F is a unique solution used for synchronous motor spindle applications.
