Motor Protection - The Enerdoor Snubber

This white paper discusses Enerdoor’s newest developed product the FIN47SNB snubber and how it benefits markets facing voltage wave reflection issues due to their use of variable frequency drives (VFDs). 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 and bearings.

Why Enerdoor's Snubber is Essential

  • Suitable for open and closed loop applications
  • Protects motor insulation and bearings
  • Increases production and lowers costs
  • Low power loss
  • Reduces temperature
  • Very stable and difficult to saturate
  • Compact case
