The invention discloses a motor control device, a motor driving device, a motor system and an electric device. The purpose of the present invention is to provide a motor control device capable of easily implementing a drive signal for each phase in a three-phase modulation control scheme by means of an analog circuit. This motor control device is provided with: a generation unit configured to receive an input voltage and generate an analog voltage that has a wave height value corresponding to the input voltage and that is equal to or greater than a reference potential; a modulation unit configured to generate a PWM voltage based on the analog voltage output from the generation unit; and an inversion unit configured to invert a duty ratio during a predetermined period of the PWM voltage. 本说明书中所揭露的涉及一种电动机控制装置、电动机驱动装置、电动机系统及电气设备。本发明的目的在于提供一种能够由模拟电路容易实现3相调制控制方式中的各相的驱动信号的电动机控制装置。本发明的电动机控制装置具备：产生部，构成为接收输入电压，产生具有与所述输入电压对应的波高值且为基准电位以上的模拟电压；调制部，构成为产生基于从所述产生部输出的所述模拟电压的PWM电压；及反转部，构成为在所述PWM电压的规定期间使占空比反转。
