摘要： A throttle valve control device is composed of a stator core with a solenoid and a rotor carrying a throttle valve. The rotor has a pair of poles which is composed of one or a plurality of rare-earth-metal permanent magnets magnetized in the radial thickness direction. The stator core has an inner periphery sorounding the rotor, and the inner periphery is smooth with no slot so that uniform distribution of magnetic flux can be formed in the inner periphery, thereby reducing the detent torque.
