摘要： 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.

摘要： Disclosed herein is a controller-integrated driving motor module. The controller-integrated driving motor module includes: a motor; a motor housing configured such that the motor is accommodated therein; a power transmission unit connected to the motor, and configured to transmit a rotational force of the motor to each part of a power seat for the movement of the power seat disposed in a vehicle; and a controller disposed between the motor and the power transmission unit, and configured to control the rotation of the motor. The controller includes a MCU configured to control the rotation of the motor, an inverter configured to receive a driving signal from the controller and drive the motor, and a power supply unit configured to receive power from the battery of the vehicle and provide the power to the controller.
