The invention discloses a bilateral permanent magnet double-electromechanical port motor. The motor comprises a stator, an intermediate rotor and an inner rotor which are coaxially nested in sequencefrom outside to inside; the stator comprises a first magnetic core, two sets of windings and multiple pieces of first magnetic steel; the intermediate rotor comprises a second magnetic core and multiple pieces of second magnetic steel; the first magnetic core is of a tooth groove structure; one or more auxiliary teeth are connected to one main tooth; the two sets of the windings are located in a groove of the first magnetic core; the first magnetic steel is located in a groove opening of the first magnetic core; the second magnetic steel is uniformly nested inside the second magnetic core; andthe first magnetic core and the second magnetic core are coaxially nested. The stator and the inner rotor are provided with the magnetic steel, so that the working magnetic density of the motor can be improved, and the torque output capability of the motor is improved; and meanwhile, two magnetic field modulation motors are realized in a motor structure, so that the structure is more compact.
Description
technical field [0001] The invention belongs to the technical field of permanent magnet motors, and more specifically relates to a bilateral permanent magnet double electromechanical port motor. Background technique [0002] In many industrial applications, especially in hybrid vehicles, continuously variable transmissions with variable speed and torque transmission ratios have attracted much attention. Existing hybrid vehicle power systems, represented by Toyota Prius, mostly use planetary gears to decouple the speed between the internal combustion engine and the wheel load; the torque between the internal combustion engine and the wheels is completed through the torque of the additional motor / generator Decoupling: After decoupling the speed and torque of the internal combustion engine and the load, the internal combustion engine can always work at the maximum efficiency point without affecting the wheel load operation. This system greatly improves the working efficiency o...
