Description

Technical Field

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

[0002] A motor is a device that converts electrical energy into mechanical energy. It uses an energized coil (i.e., a stator winding) to generate a rotating magnetic field and acts on a rotor (such as a squirrel-cage closed aluminum frame) to form a magneto-electrical rotational torque. Motors are divided into DC motors and AC motors according to the power supply used. Most motors in power systems are AC motors, which can be synchronous motors or asynchronous motors (the speed of the motor's stator magnetic field does not keep pace with the speed of the rotor rotation). When existing motors are in use, the motor housing is an integrated structure, and the housing cannot be disassembled. After the housing is heat-fitted, it is difficult to disassemble and repair it, which increases the difficulty of subsequent maintenance and repair. Therefore, we propose a motor device to solve the above problems. Utility Model Content
