Problems solved by technology
The air gap of the motor is the place where mechanical energy and electric energy are exchanged. The uniform air gap of the motor is crucial to the normal operation of the switched reluctance motor. Therefore, the relative position accuracy of the motor stator and rotor has a great impact on the performance and life of the motor. The reluctance motor has the problem of poor assembly accuracy between the end cover and the stator

The invention provides a switched reluctance motor stator and end cover assembling structure which comprises a left end cover, a stator assembly and a right end cover which are sequentially arranged, the left end cover is provided with a first bolt hole and a first positioning column, the right end cover is provided with a second bolt hole and a second positioning column, the stator assembly comprises a stator framework and a stator iron core, and the stator framework and the stator iron core are integrally formed. The stator iron core is installed on the stator framework, a connecting hole and a positioning hole which are through left and right are formed in the stator iron core, and when the two ends of the positioning hole are connected with the first positioning column and the second positioning column respectively, the first bolt hole, the connecting hole and the second bolt hole correspond to each other. By adopting the assembling structure, the motor end cover is tightly matched with the stator iron core and the rotor, the air gap precision is improved, the relative position of the stator and the rotor of the motor is maintained, the stator and the rotor are not easy to move relatively, the air gap uniformity is ensured, and the performance and the service life of the motor are improved.
Description
technical field [0001] The invention relates to the field of reluctance motors, in particular to an assembly structure of a stator and an end cover of a switched reluctance motor. Background technique [0002] Switched reluctance motor has simple structure, reliable performance, wide speed range, high output and efficiency in a wide range of speed and power, and is widely used in electric vehicles, machinery manufacturing equipment, aviation machinery and other fields. The air gap of the motor is the place where mechanical energy and electric energy are exchanged. The uniform air gap of the motor is crucial to the normal operation of the switched reluctance motor. Therefore, the relative position accuracy of the motor stator and rotor has a great impact on the performance and life of the motor. The reluctance motor has the problem of poor assembly accuracy of the end cover and the stator. [0003] For this reason, it is necessary to make further improvements to it. Conten...
