Motor

The utility model relates to a motor, which comprises a shell, a Hall element, a rotor and an adjusting device, and is characterized in that a mounting cavity is defined in the shell; the Hall element is arranged in the mounting cavity; the rotor is rotatably arranged in the mounting cavity and is positioned on one side of the Hall element along the axial direction of the motor; and the adjusting device is arranged in the mounting cavity, and the adjusting device is detachably connected with at least one of the Hall element and the shell so as to adjust the relative position of the Hall element relative to the rotor. Therefore, by arranging the adjusting device, the purpose of accurately controlling the Hall element to sense the magnetic steel distance of the rotor and adjusting the Hall angle can be achieved according to the actual situation, so that the efficiency of the motor is improved. Meanwhile, the safety distance between the Hall element and other electrified components can be adjusted. In addition,
