Abstract
The present disclosure relates to a motor for a seat sliding device of a vehicle, and includes a coil module in which a plurality of first coils and a plurality of second coils are seamlessly disposed in the circumferential direction to have a cylindrical shape. Therefore, the conventional stator core having a slot and a tooth for installing the coil is not used, thereby implementing miniaturization and light-weight of a motor. and the slot and the tooth do not exist, thereby reducing a cogging torque and reducing the vibration and noise of the motor.
Claims7
A motor for a seat sliding device of a vehicle comprising:
- a back yoke;
- a coil module inserted into and supported by the back yoke, and composed of a plurality of first coils and a plurality of second coils having a cylindrical shape in an assembled state;
- a rotor sleeve inserted into the coil module in a rotatable state;
- a permanent magnet installed on the outer circumferential surface of the rotor sleeve and having multiple poles formed in the circumferential direction;
- and
- a nut provided inside the rotor sleeve and screw-fastened to a lead screw installed on a lower rail of a seat slide rail,
- when the rotor sleeve rotates, a vehicle seat slides in the back-and-front direction along the seat slide rail.
