Motor Protection from Overvoltage Spikes
This white paper discusses Enerdoor’s approach with customers in need of protecting motors against overvoltage spikes, widely 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 causing premature degradation and failure to motor insulation.
Why Motor Protection is Beneficial
- Protects motors
- Reduces overvoltage spikes
- Suitable for open and close loop application
- Low power loss
- Reduces temperature
- Very stable and difficult to saturate
- Compact case
