AI Technical Summary
The rotor core of existing switched reluctance motors is prone to misalignment during long-term use and has poor heat dissipation, which affects the stability and performance of the motor.
Radial positioning is achieved by using a limiting protrusion and a limiting groove. The stability and heat dissipation performance of the iron core are improved by using axial limiting components and heat dissipation through holes. The axial limiting components and screws are made of insulating material and combined with the heat dissipation channel design to prevent misalignment and improve heat dissipation.
This effectively avoids rotor core misalignment, improves heat dissipation, and ensures stable operation of the switched reluctance motor.
