<P>PROBLEM TO BE SOLVED: To provide a rotary electric machine control system capable of effectively relaxing current concentration of switching elements constituting a drive circuit when a rotary electric machine repeats a lock state and a lock release state. <P>SOLUTION: A rotary electric machine control system 10 comprises: a rotary electric machine 20; an inverter circuit 30 connected to the rotary electric machine 20; a drive command section 40 for driving the inverter circuit 30 according to a torque request, etc. in relation to a vehicle; and a control device 50 for controlling operations of these elements as a whole. The control device 50 comprises: a lock determination section 52; an element temperature acquisition section 54; and a torque limit section 56, to perform a control during lock. The torque limit section 56 sets a reduction rate of a torque command value T<SP POS="POST">*</SP>48 according to an element temperature of each switching element in the rotary electric machine 20 to perform processing for reducing the torque command value T<SP POS="POST">*</SP>48. <P>COPYRIGHT: (C)2013,JPO&INPIT |
