Direct-drive switch reluctance motor with teeth arranged at shaft end

Abstract

The invention provides a direct-drive switch reluctance motor with teeth arranged at the shaft end and belongs to the field of switch reluctance motors. The direct-drive switch reluctance motor with teeth arranged at the shaft end includes a switch reluctance motor, wherein the switch reluctance motor is provided with a rotating shaft, and an interlayer is arranged in a casing of the switch reluctance motor. A water inlet and a water outlet are arranged on the casing, and the interlayer is communicated with the outside through the water inlet and the water outlet. The direct-drive switch reluctance motor with teeth arranged at the shaft end is characterized in that recesses are formed in one end of the rotating shaft and are arrayed in a circle around the circle center of the cross section of the rotating shaft, and upheavals between each two random recesses form teeth. Six wiring ports are arranged on one side of the casing, and threads are arranged in the wiring ports. Lantern rings are sleeved on insulation skins of cables, and threads are arranged on the outer portions of the lantern rings. The threads on the outer portions of the lantern rings are matched with the threads in the wiring ports, so the teeth on the rotating shaft do not loosen or shift, water and salt mist can be resisted effectively and the power lines are not apt to fall.

Description

technical field [0001] The invention provides a shaft-end toothed direct-drive switched reluctance motor, which belongs to the field of switched reluctance motors. Background technique [0002] When wiring the existing water-cooled switch side resistance motors, a junction box is often arranged on the casing, and a wiring terminal is arranged in the junction box. One end of the wiring terminal is connected to the stator, and the other end fixes the power cord. When the cover is closed, the power cord will come out from the outlet on the cover, so as to achieve the function of waterproof and anti-salt spray at the terminal; when the switched reluctance motor provides power, it needs to install a gear on its rotor with a fixing device , The rotor of the switched reluctance motor cooperates with other gears through the gears on it to make the corresponding parts of the equipment rotate. [0003] Current prior art defect is: [0004] First, because the junction box is equipped...

AI Technical Summary

Problems solved by technology

[0004] First, because the junction box and the cover have an outlet, it cannot be guaranteed that water mist and salt mist will not enter at all;

[0005] Second, the power cord is only fixed by the screw plate on the terminal, which is not firm enough to easily cause the cable to fall off from the terminal

[0006] Third, when the rotor of the switched reluctance motor rotates, it will be subjected to resistance or even collision force. These forces will first act on the gears on it, and the gears are fixed or even directly put on by the vault device. A long time will lead to loosening or stringing, which greatly affects the control accuracy of the switched reluctance motor
