Description

Technical Field

[0001] The utility model relates to the technical field of permanent magnet motors, in particular to a built-in outer rotor permanent magnet motor. Background Art

[0002] Motor 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 maintain 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, causing the motor to rotate.

[0003] However, the existing internal outer rotor permanent magnet motor does not have the function of efficient heat dissipation, which easily causes the internal outer rotor permanent magnet motor to generate a large amount of heat under long-term operation, resulting in the internal outer rotor permanent magnet motor being unable to cool down quickly, affecting the normal use of the internal outer rotor permanent magnet motor.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an internal outer rotor permanent magnet motor is proposed. Utility Model Content
