Positioning actuator and manufacturing method

Abstract

A positioning actuator includes a stator assembly and a rotor, a printed circuit provided with electronic components, as well as a reduction gear for driving a rotary member. It includes two complementary blocks, the first block being made up of a shell having thermal conductivity no lower than 1 W/m/K, the first block including the reduction gear and having a passage for the output shaft of the reducing gear as well as an open opposing surface; the second block being formed by overmoulding the stator assembly and having a rear bearing recess for the rotor, the second block having a joining surface which complements a joining surface of the first block. The actuator also includes the electronic circuit which is positioned in a space defined between the first and second blocks. The disclosure also relates to a method for manufacturing such an actuator.
