The invention provides a motor control device and a motor driver circuit, which can perform predetermined processing with good precision. According to one embodiment, there is provided a motor control device having a sensor, a detection circuit, and a controller. The sensor is disposed at a position between a winding corresponding to the first phase and a winding corresponding to the second phase in the motor. The motor includes a winding of a first phase, a winding of a second phase, and a winding of a third phase. The detection circuit detects a timing at which the magnitude relationship between the induced voltage amplitude of the first phase and the induced voltage amplitude of the second phase is exchanged. The controller performs a predetermined process with respect to the motor based on a signal of the sensor and a detection result of the detection circuit. 本发明提供马达控制装置及马达驱动器电路，能够精度良好地进行预定的处理。根据一个实施方式，提供一种具有传感器、检测电路和控制器的马达控制装置。传感器配置于马达中的对应于第1相的绕组与第2相的绕组之间的位置。马达包括第1相的绕组、第2相的绕组和第3相的绕组。检测电路检测第1相的感应电压振幅与第2相
