Problems solved by technology

However, the biggest disadvantage of single-phase switched reluctance motors is that there is no self-starting function
It has been introduced to use permanent magnet materials as auxiliary starting structure, and to embed aluminum or copper blocks between the rotor poles to use eddy current reaction torque as auxiliary starting, etc., but these methods all reduce the power per unit volume of the motor and have no effect. Ideal, and the motor can only run in one direction
As a result, it is difficult for this cheap and efficient motor to be put into practical use.

Embodiment Construction

[0015] This embodiment will be further described below in conjunction with the drawings.

[0016] Reference figure 1 , A single-phase switched reluctance type multifunctional motor with a starting winding, the single-phase switched reluctance type multifunctional motor is a single-phase variable reluctance double salient motor, the single-phase variable reluctance double salient motor It includes a stator 1 and a rotor 2. The salient stator pole 3 of the stator 1 is equipped with a field winding 4, and the salient rotor pole 5 of the rotor 2 is equipped with a start winding 6 dedicated to start. The start winding 6 is connected to a brush 7. The current direction of the start winding 6 is in a tangent relationship with the magnetic field lines of the magnetic field formed by the excitation winding 4.

[0017] The single-phase variable reluctance double salient pole motor is a hub-type motor. The rotor 2 is located outside the stator 1. The rotor 2 includes an upper outer rotor 8 a...

Abstract

The invention discloses a single-phase switch reluctance multifunctional motor with a starting winding. The single-phase switch reluctance multifunctional motor is a single-phase variable reluctance double-salient pole motor which comprises a stator and a rotor; the salient pole of the stator is provided with an exciting winding; the salient pole of the rotor is provided with the starting windingspecially used for starting; the starting winding is connected with an electric brush; and the current direction of the starting winding and the line of the magnetic force of a magnetic field formed by the exciting winding form a tangency relation. The single-phase switch reluctance multifunctional motor with the starting winding does not need to be assisted by an external force when starting andis convenient to be used.

Description

Technical field [0001] The invention relates to a single-phase switched reluctance motor, but the working principle of a DC motor is involved when it is started, and it operates according to the principle of a double salient pole variable reluctance motor after starting. Background technique [0002] Electric vehicles are a means of energy-saving and emission-reducing transportation. They have received extensive attention from countries all over the world and are recognized as energy-saving and environmentally friendly future vehicles. Any type of electric vehicle included requires an electric motor as an actuator to drive the wheels. Therefore, inventing and creating a sturdy, durable, high-efficiency, low-cost motor with multiple functions of electric, power generation feedback and electromagnetic braking at the same time is very beneficial to improving the cost performance of electric vehicles and making them popular and popular. [0003] Because electric vehicles use in-wheel ...
