摘要： Brushless motor is provided which includes an outer stator and an inner rotor having a plurality of permanent magnets. One or inner surface of the outer stator, opposed to the inner rotor, is covered with a cover formed of a magnetic material and in the shape of a cylinder of a small wall thickness. The magnetic cover has a plurality of slits inclined with respect to the rotational axis of the inner rotor. Magnetic portions formed or left between the slits of the cover are also inclined with respect to the rotational axis of the inner rotor. With such magnetic portions, boundaries between magnetic poles are virtually inclined with respect to the rotational axis of the inner rotor, so that undesired cogging torque of the motor can be minimized.

摘要： A motor rotation angle detection device includes a resolver which detects a rotation angle of a motor generating an assist torque for steering road wheels. The resolver includes an annular rotor disposed inside an annular stator with an air gap interposed in between an outer circumferential surface of the rotor and an inner circumferential surface of the stator, so that the stator and the rotor are rotatable relative to each other. A rotor supporting member is connected to a rotary shaft of the motor, and the rotor extends out from an axial end portion of the rotor supporting member so as to surround an outer periphery of the rotary shaft. With the described motor rotation angle detection device, it is possible to stabilize the magnetic permeability of the rotor, and accordingly to increase an accuracy with which the rotation angle of the motor is detected.
