Throttle valve control device |
摘要 |
<p>A throttle valve control device (10) is composed of a stator core with a solenoid (50, 55) and a rotor (41) carrying a throttle valve. The rotor (41) has a pair of poles (46, 47) which is composed of one or a plurality of rare-earth-metal permanent magnets magnetized in the radial thickness direction. The stator core (45) has an inner periphery (45a) surrounding the rotor (41), and the inner periphery (45a) is smooth with no slot so that uniform distribution of magnetic flux can be formed in the inner periphery (45a), thereby reducing the detent torque. <IMAGE></p> |
