  • Thrust compensation system of dual-winding voice coil motor
    Patent number: 9621085
    Abstract: A thrust compensation system of a dual-winding voice coil motor, which is used for driving the voice coil motor having secondary windings arranged between each pair of main windings, wherein the main windings are the main working windings of the voice coil motor and used for providing the output electromagnetic force required by the driving system of the voice coil motor; the secondary windings are compensation windings and used for providing the thrust ripple opposite to the main windings and compensating the thrust ripple of the main windings, so that the resultant force of the output thrust of the main windings and the secondary windings of the voice coil motor is constant.
