Description

TECHNICAL FIELD

[0001] The utility model relates to the motor field technology especially is a motor stator with heat dissipation function. BACKGROUND

[0002] The rotation principle of the motor is based on John Ambrose Fleming's left-hand rule. When a wire is placed in a magnetic field, if the wire is connected to a current, the wire will cut the magnetic field lines and move. The current entering the coil generates a magnetic field, which uses the magnetic effect of the current to make the electromagnet continuously rotate in the fixed magnet. The principle of the direct current motor is that the stator is fixed and the rotor moves in the direction of the force generated by the interaction. The alternating current motor is that the stator winding is connected to alternating current to generate a rotating magnetic field, which attracts the rotor to rotate together. The basic structure of the direct current motor includes "armature", "field magnet", "current collector ring" and "brush".

[0003] The motor generates a large amount of heat during work due to the limited internal space. The existing motor stator has a small heat dissipation area, so that the heat cannot be quickly dissipated, and after a long time of work, the overall temperature of the motor is too high, which not only affects the service life of the motor, but also affects the working efficiency of the motor. Therefore, it is necessary to further improve the structure of the existing motor. SUMMARY
