To provide a motor control device that specifies a type of temperature sensor by a simple technique, even in a case of the type of temperature sensor installed to a motor being unclear. A motor control device includes: a temperature detection circuit capable of mounting a plurality of types of temperature sensors as a temperature sensor installed to a motor; a storage unit that stores a plurality of conversion tables corresponding to each of the plurality of types of temperature sensors; and a motor temperature detection part that detects a motor temperature using feedback data from the temperature sensor and a conversion table corresponding to the type of temperature sensor, in which the type of temperature sensor installed to the motor is specified using comparison results between the temperature of a different motor from the motor obtained from a known type of temperature sensor or the temperature of the motor control device itself, and a plurality of calculated temperatures calculated using feedback data and conversion tables corresponding to each of the plurality of types of temperatures sensors.
