A motor drive device for driving of a plurality of motors in a proper manner, having a first motor, a second motor, and a current controller. The first motor is able to drive at up to a first maximum permissible current of A 1 . The second motor is able to drive at up to a second maximum permissible current of B 1 . The power supply supplies up to a maximum permissible supply current of D to the first and second motors. The current controller controls operations of the first and second motors. The maximum permissible supply current of D is set to be less than a sum of A 1 and B 1 . The current controller controls a first current A 2 to be supplied to the first motor and a second current B 2 to be supplied to the second motor so that a sum of the first and second current A 2 and B 2 is less than D. The current controller controls the second current B 2 to be less than the second maximum permissible current B 1.
