Electromechanical device

An electromechanical device comprising

• a stator;
• a rotor;
• and
• one or more thermoelectric generator (TEG) portions positioned to accept heat from at least one of the stator and the rotor;
• wherein the stator comprises a lamination stack;
• and
• at least one of:
• (a) the stator comprises head windings each comprising a respective ring about a respective end of the lamination stack, the one or more TEG portions comprise one or more winding-powered TEG portions covering at least most of the head windings, and the at least one respective heading winding of the head windings has a respective inner retainer running around at least most of an inside of the respective head winding and outwardly urging TEG portions against the respective heading winding;
• (b) the stator comprises head windings each comprising a respective ring about a respective end of the lamination stack, the one or more TEG portions comprise the one or more winding-powered TEG portions covering at least most of the head windings, and the at least one respective heading winding of the head windings has a respective outer retainer running around at least most of an outside of the respective head winding and inwardly urging TEG portions against the respective heading winding;
• or
• (c) the one or more TEG portions comprise one or more lamination-powered TEG portions covering at least most of an exterior of the lamination stack, and a lamination-outer retainer runs around at least most of the exterior of the lamination stack and inwardly urges TEG portions against the lamination stack.

A vehicle comprising:

• an electromechanical device that at least one of (a) moves the vehicle or another vehicle or (b) regeneratively brakes the vehicle or the another vehicle;
• wherein the electromechanical device comprises:
• a stator;
• a rotor;
• and
• one or more thermoelectric generator (TEG) portions positioned to accept heat from at least one of the stator and the rotor;
• the stator comprises a lamination stack;
• and
• at least one of:
• (a) the stator comprises head windings each comprising a respective ring about a respective end of the lamination stack,
• the one or more TEG portions comprise one or more winding-powered TEG portions covering at least most of the head windings, and
• the at least one respective heading winding of the head windings has a respective inner retainer running around at least most of an inside of the respective head winding and outwardly urging TEG portions against the respective heading winding;
• (b) the stator comprises head windings each comprising a respective ring about a respective end of the lamination stack,
• the one or more TEG portions comprise the one or more winding-powered TEG portions covering at least most of the head windings, and
• the at least one respective heading winding of the head windings has a respective outer retainer running around at least most of an outside of the respective head winding and inwardly urging TEG portions against the respective heading winding;
• or
• (c) the one or more TEG portions comprise one or more lamination-powered TEG portions covering at least most of an exterior of the lamination stack, and
• a lamination-outer retainer runs around at least most of the exterior of the lamination stack and inwardly urges TEG portions against the lamination stack.
