Patent abstract

A motor for driving an actuator used such as for a throttle valve of an automobile engine and an optical axis controller of an automobile headlight. In two cup-shaped rotor yokes each provided with an internal diameter enlarged part at its opening, a ring-shaped joint material with an external diameter fitting into this internal diameter enlarged part is inserted into the internal diameter enlarged part to form a rotor yoke assembly. A motor is available with high durability against vibration and shock owing to high accuracy in dimensions, lightweight, and high rigidity of the rotor.
