Motor Protection

The Enerdoor motor protection series protects motors from harmful overvoltage and dV/dt spikes generated by the drive’s output and is important for applications with variable frequency drives, servo drives, and long cable applications.  These output filters work with various carrier frequencies, output frequencies, and applications, and include differential mode inductance (load reactors), common mode inductance (chokes), sine wave filters, snubbers, and dV/dt filters.

This series carries CE and UL approvals and offers a current range from 3 to 1100A with unique features including: high linearity vs frequency and current, very low operating temperatures, and compact dimensions.

Benefits of Enerdoor Motor Protection:

• Increase motor life
• Protect motor windings, insulation, and bearings
• Protect against voltage spikes on the motor 
• Reduce frequent motor repairs and production downtime
• Unique solution for high-speed motor applications
• Works with various carrier frequencies, output frequencies, and applications
• Output frequencies up to 3 kHz using high-performance materials that run at ambient temps
• Pass European emission Standards; Carries CE and UL approvals
• Prevent EMC noncompliance due to radiated emissions from motor cables
• Reduce motor temperature, very low power loss
• High linearity vs frequency and current
