摘要： A winch integrated with a permanent magnet brushless motor and a controller includes a brushless motor and a controller. The brushless motor includes a stator having a wire coil, and a motor bracket. The stator is fixedly provided in the motor bracket. A rotor and a rotating shaft fixed in a rotor center are provided inside the stator. The rotating shaft is rotatably connected to the motor bracket, one end of the rotating shaft is fixedly connected with a magnet mount, and a cylinder magnet is mounted in the magnet mount. The controller includes a control circuit board fixed to one end of the motor bracket proximal to the cylinder magnet. A sensor chip for angle sensing in conjunction with the cylinder magnet is provided on the control circuit board.

摘要： An electric moving device for vehicles, relating to the trailer area, having a base frame, a travelling mechanism, a steering handle mechanism, a driving mechanism and an electric control assembly. The base frame has a support frame and a connecting frame, and the connecting frame is disposed over the support frame. The travelling mechanism has roller wheels on the support frame, and the driving mechanism has a driver and a clutch system. The driver and clutch system are located on two sides of the support frame separately. The clutch system has an input end connected to the driver in a transmission way and an output end connected to the roller wheels in a transmission way. The steering handle mechanism is rotationally fixed to the base frame so the steering handle mechanism could deflect to the two sides of the travelling direction of the moving device for vehicles.
