An Improved Approach for Connecting VSD and Electric MotorsSchneider Electric
When electric motors are connected with Variable Speed Drives, some precautions must be taken.
Motor cable length can create short time overvoltage at the motor terminal. This phenomenon results in premature ageing of the motor winding insulation, and, if not properly designed, will lead to motor failures.
End users and consultants often underestimate this problem and neglect to apply best practices or to specify adequate countermeasures. This white paper provides guidance on how to avoid this potentially problematic situation.
