摘要： A cooling fan is provided at an axial end portion of a rotor. The cooling fan generates a cooling air when rotated integrally with the rotor. On a stator core arranged at a position on a radially outer side of the rotor, a plurality of stator coils are arrayed in a circumferential direction of the stator core. Each stator coil includes a coil end that protrudes from an axial end surface of the stator core. A front housing covering the cooling fan includes: an exhaust port for passing the cooling air therethrough, at least part of the exhaust port being located at a position on a radially outer side of the coil end; and a recess portion opposed to the coil end in an axial direction.

摘要： To provide a controller and a control method which can estimate a temperature of the temperature estimation with good accuracy without depending on detection information of other sensors other than the temperature sensor, even if the temperature sensor is attached to a position away from the temperature estimation point. A controller is provided with a sensor temperature detector that detects a sensor temperature based on an output signal of a temperature sensor attached to a temperature estimation object; and a temperature estimator that calculates an estimated temperature of the temperature estimation point, based on the current detection value of sensor temperature or the current correction value of sensor temperature, the detection value of sensor temperature before the step time or the correction value of sensor temperature before the step time, and a thermal time constant.

摘要： In the insulation sheet, an insulation resin layer made of a thermosetting resin composition in an uncured or semi-cured state is formed on one or each of both surfaces of the base material. The thermosetting resin composition contains: a thermosetting resin (A) that is in solid form at 25° C.; a thermosetting resin (B) that is in liquid form at 25° C.; a latent curing agent that is unreactive at 60° C. or lower; and an inorganic filler having a maximum particle diameter smaller than a film thickness of the insulation resin layer and having an average particle diameter smaller than 0.5 times the film thickness. The insulation resin layer of the insulation sheet is efficiently compressed into a predetermined thickness by pressure application at normal temperature and permeates a gap between a stator core and a stator coil by heating during curing treatment, whereby both members can be insulated and fixed.
