The rotation speed of the motor accurately follows the set speed according to the driving signal varying as above described and the speedometer pointer connected through the eddy-current coupling to the motor indicates the vehicle speed.

摘要： An electromagnetic rotary driving device including a rotor of a permanent magnet arranged in a hole formed in a bored stator core block of a stator core, made from magnetic material. The air gap formed between the bored block of the stator core and the rotor in the direction parallel with the magnetic path in the stator core is relatively long, while the air gap formed between the bored block of the stator core and the rotor in the direction perpendicular to the magnetic path in the stator core is relatively short. In this device, the angle of rotation of the rotor is continuously changed by the current flowing through the coil of the stator without requiring a spring for return motion.

摘要： A rotary solenoid actuator for proportionally controlling the flow of fluid, such as air, in a pipe comprises a housing with a rotor rotatably mounted thereon. A stationary coreless coil for generating a magnetic field in response to a control current therethrough is mounted in the housing. A permanent magnet is affixed to a rotatably mounted shaft within the coil, and a return spring is attached to the rotating shaft. Due to low hysteresis in the coreless coil, there is a linear relationship between the control current and the fluid flow.

摘要： A rotary driving apparatus suitable for use for a flow control valve provided with a rotor valve rotatably mounted in a housing. The rotor valve is connected to a permanent magnet member. The permanent magnet member is arranged adjacent to a pair of diametrically spaced ends of a core on which a coil is wound so that the ends are oppositely magnetized to provide a two pole electric motor, stopper means is provided for allowing limited rotary motion of the rotor between a first position and a second position. The permanent magnet member is so arranged with respect to the ends of the core that a torque is, during the de-energization of the coil, generated in order to engage the stopper means. Thus, the first or second position of the rotor valve is maintained without energization of the coil.
