High speed electrical machine with embedded drive

摘要

A electrical machine with an embedded electronic control module comprising an outer housing (20) having, along an exterior surface (20B) of said outer housing, cooling fins (24) defining passages (26) therebetween, the electronic control module (36) comprising signal and power components (38) mounted on a printed circuit board (40) resting on a heat dissipater (30), wherein said heat dissipater comprises dissipating fins (30A) which protrude in the passages of the outer housing in order to increase the cooling surface and to create a turbulent effect for the common cooling fluid circulating between the heat dissipater and the outer housing.
