摘要： 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.

摘要： An apparatus and method are provided for attenuating vibration when driving an object. The apparatus includes a driving device for generating a driving force to drive the object and an attenuation actuator mounted in reciprocal relationship with the driving device for generating an attenuation force substantially concurrently with the generation of the driving force. The attenuation force is generated so as to oppose and at least partially cancel a reaction force exerted by the object in response to the driving force.
