The motor 10 is provided with a multi-stage hall sensor (not shown in the figure), so that the position can be accurately read, and the motor can be integrated with the motor 10, so that the structure is more simplified. The motor 10 has no carbon brush and longer service life, and can be applied to vehicles used in various environments, such as taxies, net-bound vehicles and the like.
The transmission assembly 20 includes a second gear 21 and at least one stage of planetary gear train 40. Each stage of planetary gear train 40 comprises a sun gear 401 arranged in the center and at least two planetary gears 402 meshed with the sun gear 401. That is, the sun gear 401 is provided at the center of one rotation plane and is rotatable; the planetary teeth 402 are eccentrically disposed on the rotation plane and mesh with the sun gear 401, so that each planetary tooth 402 can revolve around the edge of the sun gear 401 and rotate while revolving, similar to the rotation mode of each planetary around the sun, thus obtaining the name.

When the hovering locking is needed, through the position closed loop, the controller can control the motor 10 to enter a hovering mode, so that the long-time locking hovering of the vehicle door is realized, and the vehicle door does not slide at a large gradient. Therefore, when in manual operation, a manual mode can be realized by switching off the motor 10, the internal spline shaft 30 can reversely drive each stage of planetary gear train 40 and the output shaft of the motor 10 to rotate, the static resistance of the gear box and the motor 10 is skillfully designed, the static resistance is smaller, and the manual operation can be realized.

Wherein the inner wall of the fixed cylinder 22 is provided with a gear ring 221, and one side of each planetary gear 402 away from the corresponding sun gear 401 is meshed with the gear ring 221.
