Abstract:
A drive apparatus is provided which includes a motor and a control unit equipped with a cover, a heat sink, a substrate on which electronic devices are mounted. The heat sink is secured to the cover. The control unit is joined to a housing of the motor only through the cover or the heat sink. The production of the drive apparatus is achieved by fabricating the motor and then assembling the cover, which has already been fabricated with the substrate with the electronic devices and the heat sink in the sub-manufacturing line, with the housing of the motor. The drive apparatus is, therefore, produced in two main manufacturing processes, thus resulting in a decrease in manufacturing processes by one as compared with a conventional structure in which a substrate on which electronic devices are mounted or a heat sink to which the substrate is attached is joined to a motor.

Claim (Index 1):
A drive apparatus for use in an electrical power steering system which electrically assists a steering operation by a driver of a vehicle, comprising:\n a motor which includes a housing, a stator secured to the housing, and a rotor which is rotatable relative to the stator; and a control unit which includes a cover, a heat sink secured to the cover, a substrate secured to the heat sink, and an electronic device mounted on the substrate, the control unit working to control energization of a coil of the stator, wherein the control unit is secured to the housing using only one of the heat sink and the cover.
