Henka’s Motor Guarding Filters shield motor insulation from high-frequency voltage spikes caused by PWM output in Adjustable Frequency Drives (AFDs). These spikes can stress motor windings, causing insulation failure. Designed for reliability, Henka filters use optimized inductors and resistors to mitigate transients, extending motor lifespan and reducing downtime.

Technical Specifications

Tailor-Made Transformer Solutions

Henka’s Motor Guarding Filters protect motors from voltage spikes with capacities from 2A to 320A and a maximum voltage of 600V. Built with air-cooled copper windings and durable insulation (180°C for 2–11A, 220°C for 17–320A), they operate quietly below 40dBA. Designed to handle overloads up to 150% for one minute, they maintain reliable inductance under heavy loads.

Housed in a Type 1 indoor enclosure, they are CSA-certified, UL-listed, and meet IEEE and NEMA standards.
