Abstract
A control unit according to the invention has a plastic case (v) housing only power components (v), such as transistors for an inverter, among components constituting a control circuit. Other circuit components such as resistors are mounted on a printed circuit board, and the case and circuit board are secured to each other by fasteners allowing the case to be made light in weight. Screws for mounting the power components to the case are of the same size, and so are the energizing terminals. This makes possible automated assembly by robot.
