This invention discloses a self-heating and cooling permanent magnet motor, comprising a body, an output shaft mounted on the outer wall of the body, and a cover with a clearance fit between the inner wall of the cover and the outer wall of the body. The inner wall of the cover is provided with a first round rod, and the inner walls of two gears are riveted to the outer walls of two second round rods respectively. The outer walls of the two gears are provided with gear rings, and the outer walls of the gear rings are welded to the inner wall of the cover. The top and bottom of the inner walls of the gear rings mesh with the outer walls of the two gears respectively. This self-heating and cooling permanent magnet motor allows the output shaft to rotate when the body is connected to an external power source, through the clearance fit between the groove block and the block, enabling the output shaft to drive the first round rod and the first fan blade to rotate. When the first round rod is in motion, it can also drive the vertical rod and the second round rod to rotate. After reinstallation, the output shaft can still stably drive the first round rod through the engagement of the block and the groove block.
