A thermal interface for discrete semiconductor devices (such as IGBT's) having a thermally conductive structure, a PCB populated with discrete electronic components, and each of the discrete semiconductor devices having a housing extending beyond the edge of the PCB and in a direction substantially parallel to a plane of the PCB, and a clamp bar secured to the thermally conductive structure adapted to compressively secure each housing to the thermally conductive structure and adapted to maintain thermal contact between a surface of each housing and the surface of the thermally conductive structure. A thermally conductive and electrically insulative pad is positioned between the semiconductor device housing and the thermally conductive structure. A casing enclosing the interface and PCB includes the thermally conductive structure formed on a backwall of the casing.

Thermal interface for plurality of discrete electronic devices

A mass tuned damper for electric machines, particularly those with an external rotor and an internal stator in cantilever arrangement. The mass tuned damper includes a body with a predetermined mass and a mounting mechanism with a predetermined rigidity configured to couple the body onto a mounting surface of the stator. The mass tuned damper is configured, by varying the mass of body and/or the rigidity of the mounting mechanism, to oscillate at a first frequency equal to, but at least partially out of phase with, a resonance frequency of the stator.

Torsional mass tuned damper

An electric machine is described herein. The electric machine includes a casing, a stator, a rotor generally coaxial with the stator, an enclosed cooling assembly circulating a first cooling fluid within the casing, and an open cooling assembly through which a second cooling assembly can flow; the open cooling assembly cooling both the stator and the first cooling fluid.

Electric machine provided with an enclosed cooling assembly paired to an open cooling assembly

An embodiment of a liquid cooled electric machine is provided with an enclosed stator and includes a cooling assembly so configured as to allow cooling liquid to flow in the coil receiving slots of the enclosed stator to thereby cool the coils positioned therein.

Liquid cooled electric machine with enclosed stator

The external rotor for an electric machine includes a cylindrically shaped receptacle having a peripheral wall and a magnet-receiving assembly including segments assembled to the inner surface of the peripheral wall so as to define a cylindrically shaped stack. The segments are shaped so as to yield magnet-receiving portions in the ring-shaped stack, and permanent magnets are secured to the magnet-receiving portion of the magnet receiving assembly.

Inserted permanent magnet rotor for an external rotor electric machine

A cooling arrangement cast into a generally cylindrical stator having longitudinal channels provided on an internal surface thereof is described herein. The cast cooling arrangement comprising a cast heat-storing element and conduits defining a cooling path having an inlet and an outlet.
