摘要：
A motor drive system comprises a motor driven by a variable frequency power supply and a machine driven by the motor, which are mechanically connected by the drive shaft of the motor and the shaft of the machine via bearings. A stationary portion of the motor and the frame of the machine are electrically connected by a low-impedance conductor, so that a current can be caused to flow at least partially between the stationary portion of the motor and the frame of the machine.
