A motor-driven compressor includes: a compression mechanism; an electric motor that drives the compression mechanism; a driver circuit unit disposed at a position to be cooled by refrigerant drawn by the compression mechanism; a temperature detection unit that detects a temperature of the driver circuit unit; and a motor control device disposed in the driver circuit unit to control the motor. The motor control device stores a predetermined drive pattern corresponding to a temperature characteristic of the driver circuit unit after starting the motor. When the temperature detected by the temperature detection unit at a time of starting the motor is higher than or equal to a predetermined temperature, the motor control device performs a limit drive control according to the predetermined drive pattern regardless of a drive state command to the motor. |
