Description

Technical Field

[0001] The utility model belongs to the technical field of reluctance motors, and more specifically, particularly relates to a magnetic core group of a reluctance motor. Background Art

[0002] The reluctance motor is a continuously running electrical transmission device. Its structure and working principle are very different from those of traditional AC and DC motors. It does not rely on the interaction of the magnetic fields generated by the stator and rotor winding currents to generate torque, but relies on the "principle of minimum magnetic resistance" to generate torque. The most important core component of the reluctance motor is the magnetic core group. When the magnetic core group is in use, it requires a certain gap between the magnetic core group and the magnetic block. The inside of the gap will cause wear during rotation due to the absorption of dust, etc., which makes the reluctance motor produce large abnormal noises during use, which has limitations.
