In the working process of the power increasing and speed regulating device 400, when the auxiliary stator 310 needs to be moved close to the auxiliary rotor 320, a user starts the stepping motor 407 to rotate forward, the stepping motor 407 rotates the driving gear 406 clockwise, the gear 406 drives the two abutting sliding blocks 403 to slide close to each other along the guiding direction of the guiding groove 401, the abutting sliding blocks 403 drive the linkage frame 330 to slide close to each other, the linkage frame 330 drives the auxiliary stator 310 to slide close to the auxiliary rotor 320, the armature winding two 316 and the electromagnet two 323 are close to each other, at this time, after the armature winding two 316 is electrified, the torque of the main shaft 221 is increased, the power of the main motor 200 is increased, and thereafter, when the auxiliary stator 310 needs to be moved away from the auxiliary rotor 320, the user starts the stepping motor 407 to rotate in a reverse direction, the stepping motor 407 drives the driving gear 406 to rotate counterclockwise, the gear 406 drives the two abutting sliding blocks 403 to slide away from each other, the pushing slider 403 drives the linking frame 330 to slide away from each other, and the linking frame 330 drives the auxiliary stator 310 to slide away from the auxiliary rotor 320, during which the rotation speed of the main shaft 221 gradually increases.
