    • Control of a brushless DC motor which has a plurality of windings and a rotor with a plurality of magnetic poles, is accomplished by sucessively feeding the current for driving the rotor to the windings to rotate the motor. The voltage of a power source that supplies the current is measured, a threshold current level for detecting the position of the rotor relative to the winding is set based on the measured voltage, the current supplied to the winding is limited and permitted to flow again into the same winding while the rising condition of current is measured, the measured rising condition is compared with the threshold level to determine switching of the current to the next winding, and the control is repeated when it is determined that the current should not be switched to the next winding.

    • A control method for brushless DC motor having a rotor, a plurality of magnetic poles and coils of a plurality of phases involves sequentially applying a current to one phase for a prescribed time, stopping the current temporarily and then reapplying the current to the same phase. The state of the rise of the current when it begins to flow to the phase, is measured. The position of one of the magnetic poles located at a position opposite to the particular phase is detected based on the measured state of the rise of the current. In response to the position of the magnetic pole, it is determined whether the flow of the current is to be switched over to the following phase or not. If so, the current is switched over the following phase and the process is repeated. Constant speed control may be accomplished by reading information from a driven disk to determine speed, comparing the speed to a fixed speed, and selectively applying by time sharing a normal current, a brake current and an acceleration current.
    • 具有转子,多个磁极和多相的线圈的无刷直流电动机的控制方法涉及顺序地向一相施加电流达规定时间,暂时停止电流,然后将电流重新施加到同一相位。 测量当电流开始流向相的上升状态。 基于测量的电流上升的状态,检测位于与特定相位相反的位置的一个磁极的位置。 响应于磁极的位置,确定电流的流动是否切换到后续阶段。 如果是,则将电流切换到以下阶段,并重复该过程。 可以通过从驱动盘读取信息来确定速度,将速度与固定速度进行比较,并且通过分配正常电流,制动电流和加速电流的时间选择性地施加来实现恒速控制。
