    • An iron motor device includes an iron core motor the rotor of which is rotationally driven a pre-set angle by electromagnetic induction responsive to phase switching of current supply to two-phase coils wound on an iron core, and a driving control unit for generating a driving control signal based on the phase information of differentially phased backward voltages induced in the two-phase coils. The driving control unit causes shorting of the backward voltage induced in the coil the current supply in which is interrupted by phase switching of current supply to the two-phase coils by providing a pre-set time delay in the turn-off timing of the switching device connected to the coil the current conduction in which is interrupted. The method for drive controlling the iron core motor device is also disclosed.
    • 一种铁电动机装置,包括铁心电动机,该铁心电动机的转子通过电磁感应被旋转地驱动预定角度,该电磁感应响应于对绕在铁芯上的两相线圈的电流供应的相位切换,以及驱动控制单元, 基于在两相线圈中感应的差分相位反向电压的相位信息的驱动控制信号。 驱动控制单元通过在切换的关断定时中提供预设的时间延迟来使得在线圈中引起的反向电压的短路,其中的电流供应被中断,电流相对于两相线圈的供电 器件连接到线圈的电流导通中断。 还公开了用于驱动控制铁芯电机装置的方法。
