PROBLEM TO BE SOLVED: To utilize each inverter effectively at the time of driving a plurality of motors by means of a plurality of inverters. SOLUTION: In the motor driver for switching the relation of connection between first and second motors 1, 2 and first and second inverter circuits 22, 23 at a connection switching section 4, first and second control sections 51, 52 judges the current relation of connection between the first and second motors 1, 2 and the first and second inverter circuits 22, 23 and control the connection switching section 4 to switch the relation of connection between the first and second motors 1, 2 and the first and second inverter circuits 22, 23 such that the lifetime of first and second power modules 32, 42 is averaged. |
