Description

Technical Field

[0001] The present invention belongs to the technical field of motors, and particularly relates to a hybrid combined motor. Background Art

[0002] With the change of the world's energy structure, the proportion of new energy, especially clean and green electric energy, is gradually increasing. The proportion of electric energy used in prime movers is getting higher and higher, and the demand for high-performance motors is becoming stronger and stronger. Currently, the mainstream motors are mainly divided into synchronous motors and asynchronous induction motors according to the excitation structure. Motors with different structures have their own advantages. For example, in new energy electric vehicles, permanent magnet synchronous motors have higher efficiency and larger torque during low-speed movement, but during high-speed movement, especially during long-term operation, once the heat generation exceeds the demagnetization recovery curve, the motor power and efficiency will decrease, affecting the use of electric energy. In the case of asynchronous induction motors at low speeds, due to the small speed difference, the starting power is low and the efficiency is small, which is not conducive to the use of electric energy. However, at high speeds, especially during long-term operation, the induction asynchronous motor does not have problems such as heat generation and demagnetization, and its power retention performance is better. There are certain limitations in choosing either type of motor.

[0003] Moreover, the current motor structure is relatively single, and the space of many motor structures is not well utilized. To solve the problem of efficient use of electric energy at both high and low speeds and at the same time increase the power density of the motor within a certain volume range, the present invention proposes a hybrid combined motor.

[0006] Further, the shape and size of the control rod are adapted to the control rod claw groove, and the control rod and the control rod claw groove cooperate with each other.

[0007] Further, a gland labyrinth seal ring is arranged in the middle of the outer surface of the rotor housing, and a stator labyrinth seal ring is arranged on one surface of the rotor housing. A seal groove matching the stator labyrinth seal ring is opened on one surface of the stator housing.

[0008] Further, four fixing threaded holes A are circumferentially opened on the outer surface of the stator housing, and the stator housing is provided with heat dissipation fins.

[0013] The present invention has the following beneficial effects: The present invention divides the motor into several different concentric ring regions in the radial direction. The same concentric ring region where the rotor and the stator cooperate constitutes part of the power of the motor. Different concentric ring regions can adopt the structures of synchronous motors or asynchronous induction motors, and different combinations of motors with different structures can be made according to actual needs and installation size requirements. Moreover, rotors are arranged between adjacent excitation windings, maximizing the utilization of the magnetic energy of the magnetic field and avoiding the waste of power density caused by magnetic leakage.

[0014] The present invention also proposes a scheme for the rotation of the permanent magnets in the rotor. When a pressure perpendicular to the stator housing is applied to the permanent magnet rotation control rod, the control claw presses the inner ring of the permanent magnet rotation control bearing, forcing the outer ring of the control bearing to press the permanent magnet rotation control tapered ring, overcoming the elastic force of the permanent magnet rotation control rod return spring, and axially moving towards the tapered ring control head of the permanent magnet rotation slide rod in the rotor support cylinder B of the rotor housing. Under the push of the conical surface, the slide rod realizes radial movement on the rotor, and the ball head presses the slide rod contact surface of the permanent magnet rotation bracket, realizing the rotation of the permanent magnet overcoming the spring force of the permanent magnet rotation bracket. And through the permanent magnet rotation linkage connecting rod, the uniformly distributed permanent magnet rotation brackets rotate synchronously, so that after the permanent magnets are rotated, they are concentric with the winding pole shoes, reducing the air gap and enhancing the magnetic force to reach the corresponding efficiency of the synchronous motor; when the permanent magnet part is not needed, the pressure is released, and each part resets under the action of the return spring.

[0015] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. Description of the Drawings

This assembly consists of: a permanent magnet rotation slide bar 201, a permanent magnet rotation slide bar bracket 202, and a return spring 205.

[0033] As Figure 17 shown, after the stator and the rotor are fitted, one circle of winding silicon steel sheet pole shoes corresponds to one circle of the rotor to form different drive combinations; by adjusting the energization conditions of different coils, it is determined which drive mode to adopt.

[0034] Embodiment 3: This embodiment is a commutation control process of a hybrid combined motor: When a pressure perpendicular to the stator housing 1 is applied to the permanent magnet commutation control rod 115, the control claw 116 presses the inner ring of the permanent magnet commutation control bearing 326 to force the outer ring of the control bearing to press the permanent magnet commutation control cone ring 325, overcoming the elastic force of the permanent magnet commutation control rod return spring 324 to axially move towards the cone ring control head 204 of the permanent magnet commutation slide rod 201 within the rotor support cylinder B313 of the rotor housing 1. And under the push of the conical surface, the slide rod 201 realizes radial movement on the rotor. The ball head 203 presses the slide rod contact surface 306 of the permanent magnet commutation bracket 303, enabling the permanent magnet to overcome the spring force of the permanent magnet commutation bracket 303 to achieve permanent magnet commutation. And through the permanent magnet commutation linkage rod 302, the evenly distributed permanent magnet commutation brackets 303 rotate synchronously, enabling the permanent magnets to be concentric with the winding pole shoes after commutation, reducing the air gap and enhancing the magnetic force to reach the corresponding efficiency of a synchronous motor; When the permanent magnet part is not needed, the pressure is released, and each part resets under the action of the return spring.
