Description

Technical Field

[0001] The invention relates to a top-pressure positioning type motor structure. Background Art

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It uses an energized coil to generate a rotating magnetic field and acts on the rotor to form a magneto-electrodynamic rotating torque. Electric motors are divided into DC motors and AC motors according to the power supply used. Most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors. The electric motor is mainly composed of a stator and a rotor. The direction of the force movement of the energized conductor in the magnetic field is related to the direction of the current and the direction of the magnetic flux lines. The working principle of the electric motor is the effect of the magnetic field on the force of the current, which makes the motor rotate. However, when the motor's rotating shaft is assembled and rotated, it often moves back and forth to produce a gap, and the front end of the rotating shaft will produce circumferential shaking when rotating, which makes the rotating shaft unstable during assembly and operation, and at the same time it must be ensured to be stable and not loose.
