The method comprises the steps that the rotor, the stator, a front end cover, a rear end cover and a controller are installed, after an aluminum coil of the stator winding is wound, a crimping terminal technology is adopted when an aluminum wire of the stator winding is connected with the outside, a cold-pressed terminal is adopted for crimping, a heat shrink tube is adopted for sealing a crimping part after crimping, and the aluminum wire is isolated from air.

Description

technical field [0001] The invention relates to a motor, in particular to a high-efficiency energy-saving switched reluctance motor and a preparation method thereof. Background technique [0002] The switched reluctance motor has a double salient pole structure, and the salient poles of the stator and rotor are all laminated by ordinary silicon steel sheets. The rotor has neither windings nor permanent magnets, and concentrated windings are wound on the stator poles. The reluctance motor uses the principle of the minimum reluctance, the magnetic flux is always closed along the path of the minimum reluctance, and the rotor is driven to rotate by the attractive force between the tooth poles. Switched reluctance motor is a new type of speed regulation motor. The speed regulation system has the advantages of both DC and AC speed regulation systems. It is the latest generation of stepless speed regulation system following the frequency conversion speed regulation system and brus...
