Can a Motor Drive Harm an Elevator or Escalator System?

By Elevator World | August 1, 2018

Testing to reduce high-frequency currents produced by VFDs and DC controllers is conducted. Most modern elevator electric motors run via a variable-frequency drive (VFD) for AC motors and a DC controller (usually silicon-controlled-rectifier [SCR] based but, more recently for DC motors, insulated-gate-bipolar-transistor [IGBT] based) to control motor/elevator speed. Motor controllers save up to 55% in…
