The present disclosure is concerned with a stator for an electric machine comprising a plurality of stacked laminations each including inwardly facing slots defining inwardly facing teeth configured to receive prewound coils thereonto. Each slot including a generally triangular projection configured and sized as to be in proximity of the prewound coils.

Stator assembly with heat recovery for electric machines

Systems for a voltage balanced multi-set hairpin windings for electric motors are provided. The systems comprise a stator assembly of an electric motor system, a plurality of radial slots positioned around an inner cylindrical surface, and a winding scheme for the stator assembly including alternating positioning of a hairpin wire having a seven slot span and another hairpin wire having a five slot span in four sub-circuits.

System for hairpin windings in electric motors

An electric machine provided with a stator structure including internal and external layers of interleaved pre-wound coils made of rectangular wire coated with enamel insulation varnish is described herein. The two layers of pre-wound coils allow the use of slightly different size of pre-wound coils, which facilitates their insertion into the stator slots.

Stator structure with two layers of pre-wound coils

External rotor electric machine with SMC blocks interposed between permanent magnets. The machine has an internal stator and an external cylindrical rotor. Permanent magnets and SMC blocks are mounted on the inner surface of the rotor.

External rotor electric machine with SMC blocks interposed between permanent magnets

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 stator assembly is provided with detachable teeth that are made of magnetic powder material. The teeth are so configured and sized as to be interconnected to a core body of the stator with pre-formed coils that are positioned between adjacent teeth.

Stator assembly for electric machines

The present invention is generally concerned with an inductance assembly that is so configured and sized as to be inserted inside the cooling assembly of an electric machine to thereby decrease the overall volume of the machine.
