Embodiment

[0028] Example: such as Figure 1 to Figure 4 and Figure 8 , Figure 9 As shown, a high-efficiency energy-saving switched reluctance motor includes a stator 200 and a rotor 100. The stator 200 includes a stator core 230 and a winding 220. The winding 220 is composed of a number of coils distributed in a ring to form a fractional slot concentrated winding structure. The coil is mounted on the stator core 230, the rotor 100 includes a rotating shaft 150 and a rotor core 110, the rotor core 110 is mounted on the rotating shaft 150, and the rotor core 110 is provided with several rotor teeth 120, Dovetail grooves 130 are provided between the adjacent rotor teeth.

[0029] Combined stator core centralized winding technology improves the utilization rate of silicon steel sheets by more than 20%, which significantly reduces the cost of motor core materials; 120 rotor teeth are designed with dovetail grooves 130 to facilitate plastic sealing of the shape and increase connection str...

Abstract

The invention discloses a high-efficiency energy-saving switched reluctance motor, which comprises a stator and a rotor, the stator comprises a stator iron core and a winding. The winding is of a fractional-slot concentrated winding structure formed by annularly distributing a plurality of coils, the coils are installed on the stator iron core, the rotor comprises a rotating shaft and a rotor iron core, the rotor iron core is installed on the rotating shaft, a plurality of rotor teeth are arranged on the rotor iron core, and dovetail grooves are formed between the adjacent rotor teeth. The invention also discloses a preparation method of the high-efficiency energy-saving switched reluctance motor. 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...
