    • 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.

    • A control system (10) for an electric vehicle/golf car having a shunt wound motor including an amarture coil (22) and a field coil (24). The system includes one MOSFET (34) connected in parallel across the armature coil, along with a freewheel diode (42), and another MOSFET (36) connected in series with the armature coil. When the motor is operating below its based speed, i.e., when the back EMF is below the power supply voltage, current flow can be induced by momentarily turning on the series MOSFET, shorting the armature coil. Current flow in the counterclockwise direction is thus initiated, at which point the series MOSFET is turned off, resulting in a large voltage spike across the motor, causing current flow back into the battery pack. By quickly turning the series MOSFET on and off, current flow can be maintained, and regenerative braking occurs at slow speeds.
    • 一种用于电动车辆/高尔夫球车辆的控制系统(10),其具有包括马达线圈(22)和励磁线圈(24)的分流卷绕马达。 该系统包括并联在电枢线圈上的一个MOSFET(34),以及续流二极管(42)和与电枢线圈串联连接的另一个MOSFET(36)。 当电动机工作低于其基准速度时,即当反电动势低于电源电压时,可以通过瞬时接通串联MOSFET来引起电流流动,使电枢线圈短路。 因此,逆时针方向的电流流动开始,此时串联MOSFET被断开,导致电动机上的电压尖峰大,导致电流回流到电池组中。 通过快速打开和关闭串联MOSFET,可以保持电流,并且在低速下发生再生制动。
