Rotary electric machine system, rotary electric machine system-installed vehicle, and method for manufacturing rotary electric machine system

A rotary electric machine system comprising:

• a rotary electric machine including a rotor that is provided on a drive shaft and is equipped with permanent magnets, a stator disposed to face an outer circumferential surface of the rotor with a gap therebetween, and a stator coil wound around each tooth of the stator, and
• a control unit configured to generate a drive control signal for the rotary electric machine and execute drive control of the rotary electric machine by using the drive control signal generated,
• the system further comprising an information acquiring unit configured to acquire specific information about a value correlated to an induced voltage occurring in the stator coil when the rotor of the rotary electric machine is driven under prescribed conditions and acquire predetermined reference information about the value correlated to the induced voltage occurring in the stator coil,
• wherein the control unit is configured to normalize the drive control signal for the rotary electric machine on the basis of comparison between the specific information and the reference information and the normalized drive control signal is used to execute the drive control of the rotary electric machine.
