[0002] In various industrial productions such as energy, chemical industry, metallurgy, mining, oil extraction, transportation, etc., it is often necessary to use high-power drive equipment, especially drive equipment that can output high torque and high speed, such as electric motors and hydraulic motors. The stator and stator are composed of metal windings, which are expensive and restricted by technical bottlenecks such as speed regulation and heat dissipation. The output power of the electric motor is limited. The driving force of the hydraulic motor comes from the oil pump, and the power of the oil pump comes from the electric motor. Therefore, the output of a single hydraulic motor The power is also limited. If multiple hydraulic motors are used in series, although they can output high torque, it is quite difficult to keep multiple hydraulic motors running synchronously. The pressure imbalance of each hydraulic oil circuit system is prone to cause system shock. Therefore, the output torque ripple is large, the rotor is prone to vibration and vibration, the synchronization of the system is poor, and the reliability is poor.
