The invention relates to a motor drive control device and an electric device, which do not cause regenerative current to flow to a power supply and generate braking torque. This motor drive control device is provided with: (A) an inverter unit that drives a motor; (B) a disconnect switch for electrically disconnecting the power supply from the inverter unit; and (C) a control unit that controls the inverter unit so as to instruct the disconnect switch to disconnect the power supply from the inverter unit and perform switching in accordance with the speed and the braking target torque when a phenomenon that braking should be performed without causing the regenerative current to flow from the inverter unit to the power supply is detected.

    本发明涉及一种电动机驱动控制装置及电动装置,不使再生电流流向电源而产生制动转矩。本电动机驱动控制装置具有:(A)变频器部,驱动电动机;(B)分离开关,用来将电源从变频器部电分离;及(C)控制部,在检测出应不使再生电流从变频器部流向电源而实施制动的现象的情况下,以对分离开关指示将电源从变频器部分离,进行与速度及制动目标转矩对应的切换的方式,控制变频器部。
