Electric machine and a stator with conductive bars and an end face assembly

A stator for a high speed, low inductance electric machine, said stator comprising:

• a cylindrical stator core having an end face;
• slots provided on the end face, each slot running through the stator core;
• a plurality of conductor bars disposed within each slot;
• an end face assembly, said end face assembly electrically connecting at least two of the conductor bars;
• and
• wherein the plurality of conductor bars disposed within a slot are electrically connected to a single electrical phase of an excitation current.
• wherein an end of each bar protrudes outwardly from the end face receiving the ends of all the conductor bars

A method of manufacturing a stator for an electric machine, said method comprising the steps of:

• providing a cylindrical stator stack, said stack having a hollow core and a plurality of slots provided on an end face, through the core, and around the core;
• mounting said stack on a stator assembly tool, said tool having a protrusion that is received within the core;
• inserting a plurality of conductor bars within the plurality of slots;
• and
• placing an end face assembly over the end face, said end face assembly electrically connecting two or more conductor bars.
