Abstract
Official abstract text for this publication.
An electric power steering apparatus includes an electric motor, a drive torque transmission mechanism for converting a rotation of the electric motor to a linear movement and transmitting the linear movement to vehicle wheels, first and second circuit boards mounting electronic components to process a motor control command and drive the electric motor based on the motor control command, a metal control housing accommodating therein the first and second circuit boards and coupled at an outer surface thereof to the drive torque transmission mechanism, a heat transfer part located inside the control housing so as to receive heat from the respective circuit boards and a heat guide part extending from the outer surface of the control housing to the inside of the heat transfer member so as to guide the heat transferred to the heat transfer part in a direction toward the drive torque transmission mechanism.
