ELECTRONIC CIRCUIT DEVICE OF ELECTRIC ACTUATOR

摘要

PROBLEM TO BE SOLVED: To reduce noise by accommodating the connection part of a resolver 75 and a temperature sensor 78 of a motor unit 1 with a control unit 3 inside a mechanical/electrical connection chamber 9, and to prevent a control board 21 from receiving the external force.

SOLUTION: The control unit 3 includes: a casing 18; a cover 19; a bus bar module 20; and the control board 21. The mechanical/electrical connection chamber 9 is structured between a housing 2 of the motor unit 1 and the casing 18. A connector 45 for a sensor s molded integrally with the bus bar module 20 and extends to the mechanical/electrical connection chamber 9 through an opening 70 sensor connector of the casing 18 to keep a connector 77 of the resolver 75 and the like connected. Terminals 46 of the connector 45 for a sensor are connected to the control board 21 penetrating the bus bar module 20.
