ABSTRACT:
The armature coils of a brushless linear motor are cast in resin to form an armature plate. A heat sink is attached along one edge of the plate with conductive pins (e.g. aluminum pins) extending through the plate and into the heat sink. Fans, attached to the heat sink, draw air across it in order to remove heat by convection. A wireless communications link transmits commutation data and/or armature position data to a motor controller.
