Protect Motors From Harmful Overvoltage and dV/dt Spikes
Enerdoor developed the motor protection series to protect motors from harmful overvoltage and dV/dt spikes generated by the drive’s output. This is particularly useful for applications with variable frequency drives and servo drives. Enerdoor solutions include common mode and differential mode chokes, sine wave filters, and snubbers; all of which are designed to work with various carrier frequencies, output frequencies, and applications.
Motors controlled by VFDs or servo drives require additional attention to avoid overvoltage spikes, known as dV/dt. Voltage wave reflection is a function of the voltage rise time (dV/dt) and the length of the motor cables. This phenomenon creates additional overvoltage spikes which cause premature degradation and failure to the motor insulation. The challenge for OEMs, system integrators and distributors is to ensure the installed motors are well protected from overvoltage.
