CONTROL METHOD OF TANDEM MOTORS

Abstract: the present disclosure discloses a control method of tandem motors, relating to the technical field of motor control and solving problems of rotational speed synchronization, energy consumption and emergency protection of motors with axes connected in tandem. the control method includes: connecting axes of n motors in tandem, and collecting basic parameters of each motor; synthesizing a voltage space vector reference value; acquiring an expected voltage output vector; realizing the rotational speed synchronization and load balancing of the motors with the axes connected in tandem; and monitoring a working process of the motors with the axes connected in tandem in real time and solving the fault. the present disclosure greatly improves a collaboration ability of the motors, enhances fault detection and coping abilities and reduces resource consumption costs.
