Description

Technical Field

[0001] The utility model relates to the technical field of motor production, in particular to a motor stator insertion device. Background Art

[0002] Motor, also known as electric motor or engine, is a device that converts electrical energy into mechanical energy. It uses an energized coil (i.e. stator winding) to generate a rotating magnetic field and acts on the rotor (such as a squirrel cage closed aluminum frame) to form a magnetic 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 speed of the motor stator magnetic field and the speed of the rotor rotation do not keep synchronous speed). The motor is mainly composed of a stator and a rotor. The direction of the force movement of the energized wire in the magnetic field is related to the direction of the current and the direction of the magnetic flux lines (magnetic field direction). The working principle of the motor is that the magnetic field acts on the force of the current to make the motor rotate. When producing the motor, the motor stator needs to be inserted into the inside of the motor housing. When the motor stator is installed into the inside of the motor housing, due to the large top force required, it is necessary to use an insertion device to push the motor stator into the inside of the motor housing.

[0003] When using existing insertion equipment, it is usually necessary to manually position and fix the motor stator and the motor housing, and then push the motor stator into the motor housing through the insertion equipment. This assembly method cannot quickly position and fix the motor stator and the motor housing, and thus cannot quickly replace the next set of motor stators and motor housing, resulting in low assembly efficiency. For this reason, we propose a motor stator insertion device to solve the above problems. Utility Model Content
