    • An electric motor drive device 1000 includes: an inverter 3 that drives a motor 4, a voltage division circuit 2 that serves as a neutral point potential detection unit that detects a neutral point potential of a stator winding of the motor 4; and a controller 1 that estimates a rotor position of the motor 4 based on the detected neutral point potential, and that controls the inverter 3 based on an estimation result. A ground potential of the controller 1 is set to a negative side potential or a positive side potential of a DC voltage that is supplied to the inverter 3. The voltage division circuit 2 detects the neutral point potential with reference to the negative side potential or the positive side potential. The controller 1 estimates the rotor position based on a difference between a first neutral point potential detected during the ON/OFF operation of the inverter 3 and a first fixed reference potential (⅔)Emax, and based on a difference between a second neutral point potential detected during the ON/OFF operation and a second fixed reference potential (⅓)Emax.
    • 电动机驱动装置1000包括:驱动电动机4的逆变器3,用作检测电动机4的定子绕组的中性点电位的中性点电位检测单元的分压电路2; 以及控制器1,其基于检测到的中性点电位来估计电动机4的转子位置,并且基于估计结果来控制逆变器3。 控制器1的接地电位被设置为提供给逆变器3的直流电压的负侧电位或正侧电位。分压电路2参考负侧电位或 正面潜力 控制器1基于在逆变器3的接通/断开操作期间检测到的第一中性点电位与第一固定参考电位(⅔)Emax之间的差异,并且基于第二中性点电位 在ON / OFF操作期间检测到第二固定参考电位(1/3)Emax。

    • In one embodiment, there is provided a feeder that includes: a feed table on which a plurality of papers are staked in one direction, wherein some of the papers are bundled by a staple; a take-out module configured to sequentially take out the stacked papers from an outermost surface of the papers; a first detector configured to detect whether or not the staple exists in the papers within a distance h measured from the outermost surface; a controller configured to control the take-out module in a first mode or a second mode. When the staple is detected in the papers within the distance h, the controller controls the take-out module in the first mode. When the staple is not detected in the papers within the distance h, the controller controls the take-out module in the second mode.
