January 2018 - Enerdoor’s Motor Protection Range

Published on: 22/01/2018

Introducing Enerdoor’s extensive range of motor protection devices

Enerdoor Motor Protection Range by GD Rectifiers

Enerdoor has developed a Motor Protection Series to protect motors from harmful overvoltage and dV/dt spikes generated on the output. This is particular useful for applications with variable frequency drives and servo-motors.

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 sin 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 2 kHz. The high frequency inductance FIN960F is a unique solution used for synchronous spindle motor applications.
