Design of Test Rig for Elevator Driving System

The scheme of elevator drive system test rig was introduced when fourquadrant variable frequency static power supply and ACS880 frequency converter were used as test power supply and loading system power supply, respectively. The highprecision and lowuncertainty test rig was realized by using Yokogawa WT1800E sixchannel electrical parameter measuring instrument, the CT series wideband current sensor and the Kistler dualrange torquespeed sensor. The test rig used the energy closed loop feedback method to carry out the drag loading test, which could meet the requirement of comprehensive performance test of the elevator drive systems with the rated power of 30 kW or lower. The field testing showed that the equipment ran stably and reliably, the test was flexible, and the operation was simple and convenient. This method possessed high design reference value.
