Abstract:
1. A drive apparatus comprising: an electric motor that includes: at least one semiconductor module, each of which includes: the motor case includes at least one engaging portion that corresponds to the at least one special terminal; the at least one special terminal projects from the encapsulation body and is engaged with the at least one engaging portion to limit a positional deviation of the semiconductor module relative to the motor case; the motor case includes a heat releasing portion which projects from a wall surface of the motor case; the at least one semiconductor module contacts the heat releasing portion; the encapsulation body of each semiconductor module is configured into a generally parallelepiped form; six surfaces of the encapsulation body includes: the semiconductor module is positioned such that the back surface of the encapsulation body contacts the heat releasing portion; the at least one engaging portion includes an engaging portion that is formed in a right terminal receiving portion, which projects from the wall surface of the motor case; and the at least one special terminal includes a special terminal, which projects from the right lateral surface of the encapsulation body and is received in a groove formed in the right terminal receiving portion, so that the special terminal, which projects from the right lateral surface of the encapsulation body, is engaged with the engaging portion formed in the right terminal receiving portion.
