Description

Technical Field

[0001] The utility model belongs to the technical field of motors, relates to a stator and rotor, and particularly relates to a high-strength stator and rotor. Background Art

[0002] The fixed part in a motor is called the stator, on which pairs of stationary main magnetic poles excited by direct current are installed; while the rotating part is called the armature core, on which an armature winding is to be installed. After being energized, an induced electromotive force is generated, acting as a rotating magnetic field. Then an electromagnetic torque is generated for energy conversion. According to the shape of the stator winding and the embedding method, the stator winding can be divided into two categories: concentrated type and distributed type according to the different shapes of the coil winding and the embedding wiring methods. However, there are many types of motors currently produced, but there are generally problems such as relatively small output power, high precision requirements for processing technology, and inconvenient installation in the internal stator and rotor structures. Summary of the Invention

[0003] The purpose of the utility model is to provide a high-strength stator and rotor with improved output power and convenient installation for the above problems existing in the prior art.

[0004] The purpose of the utility model can be realized by the following technical solutions: A high-strength stator and rotor includes a rotor main body and a stator main body. A transmission shaft passes through the rotor main body. It is characterized in that the stator main body is divided into an outer stator main body and an inner stator main body. Both the outer stator main body and the inner stator main body are composed of a fixed cylinder part and several stator units. A plurality of winding blocks are integrally arranged on the inner peripheral wall of the fixed cylinder part, and each stator unit is evenly arranged on the corresponding winding block. The rotor main body is composed of an outer rotor and an inner rotor. There is an installation space for the outer rotor to rotate between the outer stator main body and the inner stator main body. There is an installation space for the inner rotor to rotate inside the inner stator main body. The transmission shaft passes through the inner rotor. The inner rotor and the outer rotor are integrally structured through a connecting part. The outer rotor is arranged between the outer stator main body and the inner stator main body, and drives the inner rotor to rotate under the action of both. The rotation of the inner rotor drives the transmission shaft to transmit power.

[0005] In the above-mentioned high-strength stator and rotor, a plurality of through grooves are formed on the outer rotor.

[0006] In the above-mentioned high-strength stator and rotor, the height of the outer stator main body is higher than that of the inner stator main body.

[0007] In the above-mentioned high-strength stator and rotor, a plurality of heat dissipation through holes for dissipating heat of the stator unit are formed on the fixed cylinder part.

[0008] Compared with the prior art, in this high-strength stator and rotor, the outer rotor in the rotor body is arranged between the outer stator body and the inner stator body, so as to increase the rotational speed of the rotor body and thus strengthen the output frequency of the transmission shaft.
