    • PROBLEM TO BE SOLVED: To provide a motor control device capable of performing control such as stop of slide door movement by regenerative braking or rotary driving of an electric motor, for example, on a slope.SOLUTION: A motor control device (motor control device 41) is an electric motor control device comprising a control unit (control circuit unit 50) which outputs a normal rotation command or a reverse rotation command for an electric motor (electric motor 21) to the electric motor. The control unit comprises position detection means (door opening/closing information generation circuit 54) for detecting a rotation direction of the electric motor when a detection signal (Su, Sv, and Sw) from a rotation sensor (Hall IC 48u, 48v, and 48w) for detecting electric motor rotation is input when the electric motor is non-conductive. The control unit further comprises conduction means (PWM command generation circuit 51b) for increasing a conduction duty per detection signal switching and performing conduction for rotating the electric motor in a direction opposite to the detected rotation direction.
    • 要解决的问题:提供一种电动机控制装置,其能够进行例如通过再生制动或电动机的旋转驱动来停止滑动门的控制,例如在斜坡上。解决方案:电动机控制装置(电动机控制装置 41)是电动机控制装置,其包括向电动机输出用于电动机(电动机21)的正转指令或反转指令的控制单元(控制电路单元50)。 控制单元包括位置检测装置(门打开/关闭信息生成电路54),用于当来自旋转传感器(霍尔IC 48u,48v,和48v)的检测信号(Su,Sv和Sw)检测电动机的旋转方向时 48w)用于检测电动机的旋转。 控制单元还包括用于增加每个检测信号切换的导通占空比的导通装置(PWM命令生成电路51b),并且执行用于沿与检测到的旋转方向相反的方向旋转电动机的导通。
