Abstract

A motor control device has a square metallic board, an electric-motor driving switching element mounted on the metallic board, a printed board disposed above the metallic board, a case that accommodates the metallic board and the printed board, a connection portion disposed on a side surface of the case, perpendicular to the metallic board and the printed board, that connects an electric motor and the switching element, an electric-motor controlling semiconductor element mounted in a square region of the printed board located immediately above the metallic board, a power supply component and a connector mounted outside the square region of the printed board, and a terminal that connects board surfaces of the metallic board and the printed board.

Description

technical field [0001] The present invention relates to a component mounting structure of a motor control device. Background technique [0002] As a motor control device, there is, for example, an ECU (Electronic Control Unit) used in an electric power steering system of an automobile as disclosed in Patent Documents 1 to 4 . [0003] An example of the ECU controlling the motor is the drive of the motor. The ECU includes switching elements for driving the motor, semiconductor elements for controlling the motor, power supply components, connectors, and connection parts for the motor. [0004] Switching elements are mounted on metal substrates, housings or printed substrates. The semiconductor element for motor control is composed of at least a microcomputer, a memory, and the like. The semiconductor element and the connector are mounted on a printed board. Power supply parts are mounted on printed circuit boards or resin frames. [0005] The metal substrate, the printed ...
