REDUCING RESONANT EFFECTS OF REACTIVE LOADS IN ELECTRIC MOTOR SYSTEMS

摘要

Embodiments herein relate to a drive system for an electric motor. The drive system including a DC bus (42) having a positive terminal and a ground terminal, an inverter (50) connected to the DC bus configured to provide a plurality of motor excitation signals, and an interface cable (60) operably connected to the inverter, and configured to transmit the plurality of motor excitation signals. The drive system also includes a motor (70) remote from and connected to the inverter via the interface cable, the motor responsive to the motor excitation signals and a plurality of snubber circuits (72), each of the snubber circuits having a first terminal connected to a winding of the motor, and a second terminal operably connected to a first end of a transmission line and a second end of the transmission line is connected to the positive terminal of the DC Bus.
