Abstract

A motor control device is configured to drive a first motor that rotates a first rotation body and a second motor that rotates a second rotation body. The motor control device includes a power supply unit, inverters configured to convert an output from the power supply unit to an alternating current and supply the output to the first motor and the second motor, and a control unit configured to drive the second motor using rotor position sensorless control. The control unit may be configured to not start up the second motor during a predetermined operation in which a large current flowing through the first motor is being performed.
