Motor control device and motor control system

A motor control device comprising:

• an acceleration sensor to be disposed on a printed circuit board, detect an acceleration corresponding to a posture of the printed circuit board, and output, as acceleration information, the acceleration detected;
• a temperature sensor to be disposed on the printed circuit board, detect a temperature on the printed circuit board, and output, as detected temperature, the temperature detected;
• an inverter circuit to be disposed on the printed circuit board and drive a motor;
• and
• a control circuit to be disposed on the printed circuit board, calculate posture information indicating the posture of the printed circuit board on the basis of the acceleration information, calculate temperature information indicating a temperature of a part disposed on the printed circuit board on the basis of the detected temperature, and control the inverter circuit by outputting, to the inverter circuit, a power supply command for the motor based on a temperature threshold set for each piece of the posture information, the posture information, and the temperature information.
