摘要： A motor control apparatus includes a housing base. A main body is disposed on a first surface of the housing base and includes a plurality of electronic components associated with driving of the motor. An air duct is disposed on a second surface of the housing base, and cooling air flows through the air duct. A through hole is disposed in the housing base and has a tapered inner surface. A bush is fitted and secured in the through hole. The bush has a tapered outer surface and includes a cable insertion hole and a close contact portion. A cable is disposed through the cable insertion hole and the housing base and is wired between the main body and the air duct. The cable has an outer surface in close contact with the close contact portion of the bush outside the through hole.

摘要： A power converting apparatus includes a housing base, a main body, an air duct, a pair of upright air duct walls, first and second heat generators, and a protrusion. The housing base has first and second surfaces. The main body is on the first surface. The air duct is for cooling air to flow through the air duct and is on the second surface. The upright air duct walls are on the second surface and extend from an upwind side to a downwind side. The first and second heat generators are disposed in series from the upwind side to the downwind side in the air duct. The protrusion is between the first and second heat generators to protrude from at least one of the pair of air duct walls toward a center portion of an air-flowing space for the cooling air.
