摘要： A controller (30) controls switching of IGBT devices (Q3 to Q8) of an inverter (14) according to the desired output of the permanent magnet motor (M1). The controller (30) includes: a magnet temperature detection device that detects the magnet temperature of the permanent magnet motor (M1) based on the output of a temperature sensor (40, 42); a setting device that sets a threshold value of the magnet temperature corresponding to the desired output of the permanent magnet motor (M1), based on a predetermined relation between the output from the permanent magnet motor (M1) and a critical temperature, up to which demagnetization in the permanent magnet motor (M1) is not caused; and a carrier frequency control device that, when the magnet temperature detected by the magnet temperature detection device exceeds the threshold value, changes the carrier frequency, at which the IGBT devices (Q3 to Q8) are switched, such that a ripple current superimposed on a motor current that flows through the permanent magnet motor (M1) is reduced.
