Connecting inverter drives | Schneider white paper

An Improved Approach for Connecting VSDs and Electric Motors   When electric motors are connected with Variable Speed Drives, some precautions must be taken. Motor cable length can create short time over-voltage at the motor terminal. This phenomenon results in premature ageing of the motor winding insulation, and, if not properly designed, will lead to […]
