CONTROL APPARATUS FOR ROTARY ELECTRIC MACHINE, ROTARY ELECTRIC MACHINE DRIVE SYSTEM, AND CONTROL METHOD FOR ROTARY ELECTRIC MACHINE

摘要

A control apparatus for a rotary electric machine, which has a rotary element that includes a permanent magnet, includes a magnet temperature acquisition portion, a coolant temperature detection portion and a temperature control portion. The magnet temperature acquisition portion acquires information about temperature of the permanent magnet. The coolant temperature detection portion detects temperature of a coolant that cools at least the rotary element. The temperature control portion performs a temperature raising control of the permanent magnet when the temperature of the permanent magnet is less than or equal to a first threshold temperature and the temperature of the coolant is less than or equal to a second threshold temperature.
