Abstract
A motor electronics unit includes a printed circuit board having a first side and a second side with electronic components connected to the printed circuit board. An electrical conductor is connected to the printed circuit board. A heat sink is connected to the printed circuit board. A pre-molded electrical connector shroud has a portion of the electrical conductor positioned within the electrical connector shroud. A housing has an endcap, both co-molded in a low pressure injection molding process of a thermally conductive polymeric material. The endcap encapsulates the printed circuit board including the electronic components connected to the printed circuit board and covers a first portion of the heat sink, with a second portion of the heat sink uncovered by the polymeric material of the endcap to permit heat transfer away from the printed circuit board. The endcap also encapsulates a portion of the electrical connector shroud.
