Abstract:
A motor drive system includes: a flywheel; a servomotor for buffer which includes a plurality of independent windings and allows the flywheel to rotate; a plurality of inverters for buffer respectively connected to the windings; a plurality of converters respectively connected to the DC links; inverters for drive which perform power conversion between a DC power in the DC links and an AC power which is a drive power or a regenerative power of the servomotor for drive; and a motor control unit for buffer configured to control driving of the servomotor for buffer by controlling power conversion of the respective inverters for buffer respectively connected to the windings.
