An actuator device for an electric window winder (101) having an electric motor (104) and a window displacement actuator element (112) which is displaceable with respect to a frame (102) of the device under action of the electric motor (104). An electronic unit (27) for drive and control of the electric motor (104) has power elements and is housed in a first portion (120) of the frame (102), and the electric motor is housed in a second portion of (107) of the frame (102). The first and second portions (120, 107) of the frame (102) are formed by a single one-piece body part of the frame, and the power components of the electronic unit (27) are in direct thermal contact with the first portion (120), which is formed of a thermally conductive metal material for the dissipation of heat from the power components.
An actuator device for an electric window winder having an electric motor and a window displacement actuator element which is displaceable with respect to a frame of the device under action of the electric motor, comprising an electronic unit for drive and control of the electric motor, said electronic unit having active power elements and being housed in a chamber formed by a first portion of said frame, and said electric motor being housed in a chamber formed by a second portion of the frame;
An electric window winder for a motor vehicle comprising an electric motor, a window displacement actuator element which is displaceable with respect to an actuator frame under action of the electric motor, and an electronic unit for drive and control of the electric motor, said electronic unit having active power elements and being housed in a first portion of said actuator frame, said electric motor being housed in a second portion of the actuator frame, and said actuator element being received in a third portion of the actuator frame;
