Title:
ELECTRIC POWER STEERING DEVICE
Document Type and Number:
Japanese Patent JP2017085884
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electric power steering device capable of respectively easily connecting an electric motor and a rotation position sensor to a control circuit for driving and controlling the electric motor.SOLUTION: An ECU housing 45 is installed on one end of a motor housing 31 in an axial direction to form a control circuit storage part 48 between the motor housing 31 and the ECU housing 45. In the control circuit storage part 48, there are provided a resolver 73 being a rotation position sensor for detecting a position of a motor rotor 33 in a rotational direction and a control circuit 49 for supplying electric power to an electric motor M on the basis of an output signal of the resolver 73. The resolver 73 and the electric motor M are electrically connected to the control circuit 49 in the control circuit storage part 48.SELECTED DRAWING: Figure 4
