Controller for rotary electric machine
To provide a controller for a rotary electric machine capable of suppressing occurrence of an angle interval when the rotary electric machine cannot output torque, even if the ON angle interval of the switching devices is set smaller than 120 degrees in the rectangular wave control. A controller for a rotary electric machine performs a rectangular wave control to a rotary electric machine which has 2 groups of three-phase windings, with a phase difference between groups; and switches a first control mode and a second control mode according to a switching condition; wherein the first control mode is a mode which sets an ON angle interval to an angle within a range from 120 degrees to 180 degrees; and wherein the second control mode is a mode which sets the ON angle interval to an angle within a range from 90 degrees to 120 degrees.
