  • VOICE COIL MOTOR AND METHOD OF USING THE SAME FOR DISPLACEMENT CONTROL
    Publication number: 20070205674
    Abstract: The present invention proposed a voice coil motor and a method of using magnetic restoring force for displacement control. The voice coil motor comprises a magnetic member and an electric member. The magnetic member generates a magnetic field. The electric member includes at least a coil and a ferromagnetic component. The coil can generate thrust when current is applied, and the ferromagnetic component can generate magnetic restoring force and normal coupling force. The voice coil motor further includes a suspension member, and is characterized in that the normal coupling force can preload the suspension member to eliminate the tilt angle and free play. Through the balance between the thrust generated by the coil current and the magnetic restoring force, open-loop displacement control can be accomplished without any elastic component.
