Embodiment 1
[0016] The intermediate frequency asynchronous motor is constituted as follows: a front end cover 1, a housing 2, a stator 3, a rotor 4, a rear end cover 5 and a shaft 6; , the front end cover 1, the rear end cover 5 and the housing 2 form the main structure, which plays a supporting role. The stator 3 is crimped inside the housing 2, the rotor 4 is crimped on the shaft 6, and the two ends of the shaft 6 pass through the bearings respectively. Cooperating with the front end cover 1 and the rear end cover 5, the rotor 4 is provided with a groove, the width of the notch is greater than the width of the bottom of the groove, the width of the notch is 1.5 times the width of the rotor tooth, and the height of the groove is 2 / 3 of the width of the notch. The motor drives the load to move by outputting mechanical torque through the shaft.

The invention discloses an intermediate-frequency asynchronous motor. The intermediate-frequency asynchronous motor comprises a front end cover (1), a shell (2), a stator (3), a rotor (4), a rear end cover (5) and a shaft (6), wherein the front end cover (1) and the rear end cover (5) are in threaded connection with the two ends of the shell (2), the stator (3) is pressed inside the shell (2), the rotor (4) is pressed on the shaft (6), the two ends of the shaft (6) are respectively matched with the front end cover (1) and the rear end cover (5) through bearings, grooves are formed in the rotor (4), the notch width is larger than the groove bottom width, the notch width is 1.5 times of rotor teeth width, and the groove height is two thirds of the notch width. After the motor rotor adopts skin effect type grooves, the current density of the rotor is effectively reduced, the influence generated by a skin effect on the rotor current is reduced, and the motor performance is improved. The intermediate-frequency asynchronous motor has the advantages of simplicity in structure, running reliability, firmness and durability.
