Abstract
(EN)
A motor assembly having an inverter with a plurality of transistor assemblies. Each of the transistor assemblies can include a surface mount MOSFET, a heat sink, and a solder material. The MOSFET has a plurality of blade terminals and a surface mount terminal that is electrically coupled to one of the blade terminals. The heat sink has a base and a plurality of fins that extend from the base. The base defines a pocket having a bottom surface. The MOSFET is received into the pocket such that the surface mount terminal is disposed proximate the bottom surface. The solder material thermally coupling the surface mount terminal to the heat sink.

L'invention concerne un ensemble moteur ayant un onduleur ayant une pluralité d'ensembles transistors. Chacun des ensembles transistors peut comprendre un MOSFET monté en surface, un dissipateur thermique et un matériau de soudure. Le MOSFET a une pluralité de bornes à lame et une borne de montage en surface qui est électriquement couplée à l'une des bornes à lame. Le dissipateur thermique possède une base et une pluralité d'ailettes s'étendant à partir de la base. La base délimitant une poche ayant un fond. Le MOSFET est logé dans la poche de telle sorte que la borne de montage en surface soit disposée à proximité du fond. Le matériau de soudure couple thermiquement la borne de montage en surface au dissipateur thermique.
