The invention provides a double-rotor disc-type hub motor and a control method thereof. The motor comprises a wheel axle, a hub, a double-rotor motor and a control unit of the double-rotor motor, a sliding groove is formed in the wheel axle in the radial direction, a pair of fixed pulleys are arranged on the outer side of the sliding groove, a steel wire with one end fixed to a stator and the other end fixed to a roller is arranged on each fixed pulley, and the roller is driven by the coiling motor to rotate; a locking mechanism is installed on the inner side of the sliding groove; and the double-rotor motor comprises an outer motor composed of a rotor and an outer stator winding, and an inner motor composed of an inner rotor and an inner stator winding. By utilizing the motor, a driving mode can be switched to a neutral gear mode, and the neutral gear mode can be switched to an outer rotor driving mode, an inner rotor driving mode and an inner and outer rotor common driving mode. According to the control method, through self-locking of the inner rotor and the outer rotor, the self-locking torque and the reaction torque are dynamically equal, and minimum current self-locking is achieved. The problem that accurate control is difficult due to the fact that the power interval of the hub motor is too large is solved, and multi-gear driving and braking of the hub motor are achieved.
Description
technical field [0001] The invention belongs to the technical field of power transmission mechanism and control of a hub motor of an electric vehicle, and in particular relates to a double-rotor disc hub motor and a control method thereof. Background technique [0002] As people pay more and more attention to environmental protection and energy saving, electric vehicles are attracting more and more attention. At present, centralized motor drive is the main driving form of electric vehicle power. Although the centralized motor drive has the advantages of easy layout of the drive system and relatively simple control system, there are still some problems. Because there are mechanical transmission systems such as clutches, transmissions, final reducers, and transmission shafts in electric vehicles driven by centralized motors, not only the chassis structure is relatively complicated, the space in the car is narrow, but also the mechanical transmission system will cause energy l...
