Rotary electric machine having a stator made up of sectors assembled together
First Claim
1. A rotary electric machine including a stator, powered by a polyphase current, having a magnetic circuit with teeth forming intervening slots for receiving electrical conductors, wherein said magnetic circuit comprises an assembly of sectors defining air-gaps intersecting said teeth at half-width, and wherein the number of teeth nteeth is in compliance with the relationship nteeth=npairs*nphases, where npairs is the number of pairs of poles and nphases the number of phases, wherein the sectors are held together by radial compression forces exerted on the sectors by a cylindrical case.
