Claims11
A motor control device comprising:
- a circuit board;
- a first power conversion circuit mounted on the circuit board and configured to supply current to drive a motor;
- a second power conversion circuit mounted on the circuit board and configured to supply current to drive a motor identical to or different from a motor to which current is supplied by the first power conversion circuit;
- a temperature detection circuit including a temperature detection element;
- and
- a control circuit configured to limit current supplied by the first power conversion circuit and current supplied by the second power conversion circuit, based on temperature detected by the temperature detection circuit,
- wherein the temperature detection element is mounted on the circuit board on which the first power conversion circuit and the second power conversion circuit are mounted and are arranged at a position between the first power conversion circuit and the second power conversion circuit.
