    摘要： A motor drive device including a substrate, a control unit packaged over the substrate for generating a pulse width modulation signal; insulation means packaged over the substrate, a gate drive circuit packaged over the substrate and connected through the insulation means with the control unit for generating a transistor drive signal in response to the pulse width modulation signal coming from the control unit, and an inverter including a plurality of transistors for generating a phase current by turning ON/OFF the transistors in response to the transistor drive signal coming from the gate driver circuit. A wiring pattern and a substrate ground are formed at the side of the substrate closer to the control unit. Only the wiring pattern is formed at the side of the substrate closer to the gate drive circuit.

    摘要： A revolving-flux type motor is provided with a stator including a coil wound around an iron core and a rotor including permanent magnets fixed to an iron core. The permanent magnets of the rotor have peripheries which form a circle as a whole when fixed to the iron core and bottoms of which configurations are determined to form a flux density distribution of a sinusoidal waveform at a gap between the stator and the rotor. The iron core of the rotor has an outer peripheral configuration which allows face-contact with the bottoms of the permanent magnets.

    摘要： Inside a housing, there are provided a motor generator (MG), an IPM, and a smoothing capacitor. Between the MG and the IPM, there is provided a cooler through which a coolant liquid flows, provided in an inclined manner to form contact with the top face of the IPM. Between the MG and the smoothing capacitor, there are provided a first communication channel through which an LLC flows from a region outside the housing into the cooler, brought into contact with a lateral face of the smoothing capacitor, and a second communication channel through which the LLC flows from the interior of the cooler to the region outside the housing.
