Original Abstract Submitted
According to one embodiment, a motor control device includes a sensor, a detection circuit, and a controller. The sensor is at a position between a winding of a first phase and a winding of a second phase in a motor. The motor includes windings of three phases. The detection circuit detects when a magnitude relationship between an induced voltage amplitude of the first phase and an induced voltage amplitude of the second phase is switched. The controller performs based on a sensor signal from the sensor and a detection result sensor from the detection circuit.
