  • Motor used to drive optical elements
    Patent number: 7683512
    Abstract: A motor used to drive optical elements includes a stator, a rotor revolved relative to the stator, and a feedback apparatus used to sense the position of the rotor. The feedback apparatus is an encoder. Such described structure eliminates the system's instability caused by the drift of a conventional capacitive type transducer or an inductance type transducer. Moreover, the response of the motor used to drive optical elements has been improved greatly by utilizing a multipole motor.
    Type: Grant
