A system for controlling plurality of synchronous motors connected in parallel including a motor drive, current sensor, and plurality of synchronous motors connected in parallel to the motor drive. The synchronous motors connected to the motor drive can include the same size and power rating to allow synchronous operation and have similar load capacity. Further, the system can operate with substantially similar loads on each of the plurality of synchronous motors. The motor drive can be a variable speed drive using vector control and a closed loop current controller to control the motors. The motor drive can be a variable frequency drive using scalar control and open loop controller to control the motors. The motor drive controls the plurality of synchronous motors by maintaining net active power and net active power, and by rejecting power perturbations, at the common node.
