Torque Decoupling Vector Control of Novel Hybrid Rotor Double Stator Synchronous Motor

In order to improve the torque density of low-speed direct-drive permanent magnet synchronous motor and make full use of its inner cavity space,this paper proposes a new hybrid rotor double stator synchronous motor and its vector control system.The rotor side of the motor adopts a surface-mounted permanent magnet rotor structure,and the other side adopts a reluctance rotor structure.The new hybrid rotor structure also solves the problem of high cost of the conventional double stator permanent magnet synchronous motor.A new torque decoupling vector control method is proposed for this new type of special motor.The torque decoupling coefficient of the internal and external motors is realized by the torque decoupling coefficient.In the Matlab/Simulink simulation environment,the new hybrid rotor double stator synchronous motor and its vector control system are modeled and simulated,and its running performance is analyzed.The simulation results verify the feasibility and correctness of the proposed motor model and its control system,and the control effect is ideal.
