Enerdoor: Line Reactor Filter

Motor Protection

In applications with variable frequency drives or servo-motors, the need arises to reduce over-voltages generated on the output, as this is harmful to motors. For this reason Enerdoor developed the motor protection series. 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 series is used with fundamental frequencies up to 2 kHz. The high frequency inductance FIN960F is a unique solution used for synchronous motor spindle applications.
