Description

Technical Field

[0001] The utility model relates to the technical field of punching devices, in particular to a three-phase asynchronous motor end cover punching device. Background Art

[0002] The three-phase asynchronous motor is a type of induction motor. It is a type of electric motor powered by a 380V three-phase AC power supply (phase difference of 120 degrees) at the same time. Since the rotor and the stator rotating magnetic field of the three-phase asynchronous motor rotate in the same direction and at different speeds, there is a slip rate, so it is called a three-phase asynchronous motor. After the stator is energized by current, part of the magnetic flux passes through the short-circuit ring and generates an induced current in it. The current in the short-circuit ring hinders the change of the magnetic flux, causing the magnetic flux generated by the part with the short-circuit ring and the part without the short-circuit ring to have a phase difference, thereby forming a rotating magnetic field. After power is turned on and started, the rotor winding generates electromotive force and current due to the relative motion between the rotor and the magnetic field, that is, the rotating magnetic field has a relative speed with the rotor, and interacts with the magnetic field to generate electromagnetic torque, so that the rotor rotates and energy conversion is realized.

[0003] For example, the Chinese authorized patent document with publication number CN 209057081 U (a three-phase asynchronous motor end cover punching device) includes a base, a telescopic cavity, a telescopic column, a fixed seat, and a motor. The utility model controls the downward movement of the drill bit by manually operating the rotation of the steering wheel and combining the mutual engagement of the gears and the teeth to perform a punching operation on the end cover in the groove.

Therefore, a three-phase asynchronous motor end cover punching device is proposed. Utility Model Content
