To provide a power supply circuit and a motor control device, capable of suppressing complexity of power supply circuit management.SOLUTION: A switching unit 70 acquires identification information I which is information according to a type of a torque sensor 50. The switching unit 70 outputs either a reference voltage Vref or a power supply voltage Vcc as a standard voltage based on the acquired identification information I. A voltage application unit 60 applies an operating voltage Vt according to the type of the torque sensor 50 to the torque sensor 50 based on the power supply voltage Vcc or the reference voltage Vref which is the standard voltage of the voltage application unit 60 applied by the switching unit 70.SELECTED DRAWING: Figure 1

    【課題】電源回路の管理の煩雑さを抑えることができる電源回路及びモータ制御装置を提供する。【解決手段】切替部70は、トルクセンサ50の種類に応じた情報である識別情報Iを取得する。切替部70は、取得した識別情報Iに基づいて、参照電圧Vrefあるいは電源電圧Vccのいずれか一方を基準電圧として出力する。電圧印加部60は、切替部70により印加される電圧印加部60の基準電圧である電源電圧Vccあるいは参照電圧Vrefに基づいて、トルクセンサ50の種類に応じた動作電圧Vtをトルクセンサ50に印加する。【選択図】図1
