Abstract
Provided are a power supply circuit and a motor control device configured to suppress complexity in management of the power supply circuit. A switching unit acquires identification information that is information corresponding to a type of a torque sensor. Based on the acquired identification information, the switching unit outputs either a reference voltage or a power supply voltage as a standard voltage. A voltage application unit applies to the torque sensor an operation voltage in accordance with a type of the torque sensor based on the power supply voltage or the reference voltage that is the standard voltage of the voltage application unit and that is applied by the switching unit.
