摘要： Power saving is implemented by cutting power to a compressor driver (31a) and a fan driver (31b) while operating power is kept supplied to a control substrate (307). After the power source to the control substrate (307) is turned on, power is supplied to the compressor driver (31a) and the fan driver (31b). Then, when it is determined that an indoor unit is in operation, the compressor driver (31a) and the fan driver (31b) are operated. Meanwhile, when it is determined that the indoor unit is not in operation, after the lapse of ten minutes or twenty minutes under a predetermined setting, the power to the compressor driver (31a) and the fan driver (31b) is cut. When the operation of the indoor unit is started again, power is supplied to the compressor driver (31a) and the fan driver (31b).

摘要： In the present invention, at a time of a heating high-load operation, a harmonic current is flown in an armature winding (16CR) to induction-heat rare-earth magnets (14MRb), thus reducing a residual magnetic flux density. Thereby, the number of rotations of a radial gap type motor (10R) is improved. The rare-earth magnets (14MRb) are provided near a cooling medium passage (30P) extending substantially in parallel with a flow line of a cooling medium, so that the cooling medium recovers heat of the heated rare-earth magnets (14MRb). At a time of a cooling high-load operation, a greater number of rotations are obtained with respect to the same torque command value, by a field weakening control by means of a current-phase advance.

摘要： Plural systems of switching signals are obtained from a single microprocessor for driving a plurality of motors and other apparatuses while achieving effective use of ports of the microprocessor. In principle, three kinds of switching signals based on three-phase are generated in the microprocessor, the three kind of switching signals are converted to six kinds of switching signals in circuits external to the microprocessor, and then the signals are supplied to their respective switching elements in an inverter circuit.
