    Abstract: A system for synchronizing a plurality of motors is disclosed. The system includes a universal drive controller which can control the operation of two motors, a power module for each motor, and a power module interface rack which is utilized to interconnect the motor to its associated universal drive controller. If a plurality of universal drive controllers is involved, a common clock is utilized to synchronize the operation of same.Synchronization of the motors is achieved by monitoring the output shaft of each motor through the use of a resolver, transmitting feedback data relative to the position of the output shaft to the universal drive controller via the power module interface rack, calculation of command data by the universal drive controller to effect synchronization, and transmitting the command data to the power module interface rack wherein the power module causes the proper firing signals to be transmitted to the associated motor. Since the operation of the universal drive controller is synchronized, and each motor is synchronized to its associated universal drive controller through its associated power module interface rack, the operation of all of the motors is synchronized.

    Abstract: A control method for a semi-centralized open winding multi-motor drive system includes: first, measuring current, voltage and position signal, computing system thrust by a velocity loop; then, distributing the thrust to each motor, converting the thrust into q axis current, computing dq axis voltages required for each motor by a current loop, and transforming the voltage demand to abc coordinate system through coordinate transformation; subsequently, modulating the voltage of each motor into a duty ratio instruction to judge whether the motor is in an over-modulated operating area, and performing over-modulation processing on the voltage in the over-modulated area; and finally, distributing the duty ratio instructions to independent and shared inverters. The control method of the present disclosure can reduce the hardware cost and improve the safety and reliability of the system.
