Enerdoor Motor Protection Filters are specifically designed to protect motors and variable frequency drives (VFDs) from electrical disturbances, voltage spikes, and insulation stress caused by long motor cables and high switching frequencies.
These filters effectively reduce dV/dt, minimize bearing currents, and protect motor windings from premature failure — ensuring longer motor life, reducing temperature inside the motor, improved reliability, and lower maintenance costs.
Enerdoor offers a complete range of motor protection devices, including dV/dt filters, sine wave filters, and output reactors, suitable for various industrial applications such as automation, conveyors, HVAC, pumps and fans.
We also have a unique solution using an hybrid material that very effective with high speed motor applications.
