Abstract
An electromagnetic armature comprising an electromagnetic yoke having a cylindrical surface of axis z, intended to be facing an air-gap. Said cylindrical surface is the interaction surface and comprises a plurality of teeth forming poles, associated with the interaction surface and projecting from same, and disposed at regularly spaced intervals around the whole yoke. Each tooth comprises a recess arranged on one of the faces of the tooth in a so-called polar plane. Each recess is intended to receive the winding. Said teeth are disposed on the yoke in such a way that the recesses are disposed alternately to either side of the polar plane. Alternatively, one or more teeth of the armature can be removed from the yoke.
