Abstract
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.
