Abstract
A motor drive architecture is provided. The motor drive architecture includes a three-dimensional (3D) stack of cold plates on which power electronic components for an electric machine are mountable and supporting structures. Each cold plate has an annular shape with internal fluid pathways. The supporting structures hold the cold plates in the 3D stack. At least one supporting structure defines an internal cavity bifurcated into an internal inlet fluid pathway configured to direct fluid into the internal fluid pathways of each cold plate and an internal outlet fluid pathway receptive of the fluid from the internal fluid pathways of each cold plate.

A motor drive architecture, comprising:
- a three-dimensional (3D) stack of cold plates on which power electronic components for an electric machine are mountable,
- each cold plate comprising a cold plate body having an annular shape with internal fluid pathways extending through an interior of the cold plate body;
- and
- supporting structures to hold the cold plates in the 3D stack,
- at least one supporting structure defining an internal cavity bifurcated into an internal inlet fluid pathway configured to direct fluid into the internal fluid pathways of each cold plate and an internal outlet fluid pathway receptive of the fluid from the internal fluid pathways of each cold plate.
An integrated motor drive architecture, comprising:
- an electric machine comprising a stator, a rotor, a shaft which is driven to rotate by an electromagnetic field induced by current applied to windings of the stator;
- and
- a three-dimensional (3D) stack of cold plates on which power electronic components for controlling applications of the current to the windings are mountable,
- each cold plate comprising a cold plate body having an annular shape, which is fittable about the shaft, with internal fluid pathways extending through an interior of the cold plate body;
- and
- supporting structures to support each of the cold plates in the 3D stack,
- at least one supporting structure defining an internal cavity bifurcated into an internal inlet fluid pathway configured to direct fluid into the internal fluid pathways of each cold plate and an internal outlet fluid pathway receptive of the fluid from the internal fluid pathways of each cold plate.
