Abstract
A control interface device for an electric motor, particularly an electric motor for operating servomechanisms on a vehicle, which includes a conductor frame, an active integrated component mounted on the conductor frame, and a plurality of electric connectors. A single insulating, one-piece enclosing body contains the conductor frame with the active integrated component and the electric connectors included to the conductor frame. Thus, all of the elements required for powering and controlling the motor are gathered inside a single enclosing body which is convenient to handle and connect.
Claims21
A control interface device for an electronic motor, comprising:
- a plurality of leads formed of a common conductive material, and sharing a substantially common plane;
- an integrated circuit mounted on at least one of said leads, and electrically connected to others of said leads;
- an enclosing body of an electrically insulative material which surrounds said integrated circuit and at least a portion of each said lead;
- said body including through-holes therein which pass through said body, in a direction substantially normal to said plane, and which abut one of said leads therein;
- some ones of said leads extending out of said body to provide a plurality of parallel electromechanical connectors.
An electronic motor assembly, comprising:
- a housing which encloses a motor and which has an aperture therein with substantially rigid studs protruding through said aperture to provide electrical connection to said motor;
- and
- a plurality of leads formed of a common conductive material, and sharing a substantially common plane;
- an integrated circuit mounted on at least one of said leads, and electrically connected to others of said leads;
- an enclosing body of an electrically insulative material which surrounds said integrated circuit and at least a portion of each said lead;
- said body including apertures therein which provide openings into said body in a direction substantially normal to said plane, and which abut one of said leads therein;
- some ones of said leads extending out of said body to provide a plurality of parallel electromechanical connectors.
A method of assembling an electronic motor assembly, comprising the steps of:
- (a) providing a housing which encloses a motor and which has an aperture therein with substantially rigid studs protruding through said aperture to provide electrical connection to said motor;
- (b) inserting, onto said studs, a solid control module which includes at least one integrated circuit encapsulated therein, and which has apertures therein in a pattern which generally corresponds to said studs, and including concealed internal electrical connections to at least some of said apertures;
- said solid control module also having lateral connectors, which are normal to said studs;
- and
- (c) inserting a connector, onto said lateral connectors of said solid encapsulated control module, to provide power, signal, and ground connections.
A control interface device for an electronic motor, comprising:
- a plurality of leads formed of a common conductive material, and sharing a substantially common plane;
- an integrated circuit mounted on at least one of said leads, and electrically connected to others of said leads;
- an enclosing body of an electrically insulative material which surrounds said integrated circuit and at least a portion of each said lead;
- said body including through-holes therein which pass through said body, in a direction substantially normal to said plane, and which abut one of said leads therein;
- wherein said enclosing body is also extended to provide alignment pins parallel to said connectors
- some ones of said leads extending out of said body to provide a plurality of parallel electromechanical connectors.
