Embodiment Construction

[0023] Various embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] see figure 1 , in one embodiment, a double-stator switched reluctance motor without housing 100 includes: an outer stator 1 , an inner stator 2 and a rotor 3 disposed between the outer and inner stators 1 and 2 .

[0025] Wherein, the inner wall of the outer stator 1 is provided with a plurality of first grooves 11 for accommodating winding coils 111 along the circumference, and protrusions between the first grooves 11 form outer stator teeth 12 .

[0026] The outer wall of the inner stator 2 is provided with a plurality of second grooves 21 for accommodating winding coils 211 along the circumference, and protrusions between the second grooves 21 form inner stator teeth 22 .

[0027] Both the inner wall and the outer wall of the rotor 3 are provided with a plurality of protrusions along the circumferential direction to form inner ...

Abstract

The invention discloses a dual-stator switch reluctance machine without a shell. The dual-stator switch reluctance machine without the shell comprises an outer stator, an inner stator and a rotor, wherein the rotor is arranged between the outer stator and the inner stator, a plurality of first grooves are formed in an inner wall of the outer stator along a circumferential direction and are used for accommodating a winding coil, bulges among the first grooves form outer stator teeth, a plurality of second grooves are formed in an outer wall of the inner stator along a circumferential direction and are used for accommodating a winding coil, bulges among the second grooves form inner stator teeth, and a plurality of bulges are arranged on both of an inner wall and an outer wall of the rotor to respectively form inner rotor teeth and outer rotor teeth. By the dual-stator switch reluctance machine without the shell, the problem that a torque ripple is excessively obvious can be prevented.

Description

technical field [0001] The invention relates to the field of motors, in particular to a casing-less double-stator switched reluctance motor. Background technique [0002] With the depletion of non-renewable energy sources, the search for renewable energy sources and how to improve energy utilization will become the main direction of attack in various fields, especially the pure electric vehicle industry and the elevator industry. [0003] At present, the switched reluctance motor has the following advantages: 1. High reliability; 2. Large starting torque and low starting current; 3. It is suitable for frequent starting and stopping and forward and reverse conversion operation; 5. High efficiency and low loss; 6. Simple structure and low manufacturing cost, making it a new favorite in the pure electric vehicle industry and elevator industry. [0004] However, everything has two sides, and the switched reluctance motor still has the following disadvantages: 1. There is torque...
