Abstract
A winding guide for an electric machine rotor includes a base that is substantially circular about a longitudinal axis, teeth which rise radially from the base, and heads which extend at the free ends of the teeth and which project from the teeth, in cantilevered fashion. At least one of the heads has an inner face turned towards the base including a flat main portion which is inclined by a first angle strictly greater than 0 degrees with respect to the longitudinal axis, and ribs which protrude from the main portion and the vertices of which are flat and inclined with respect to the longitudinal axis by a second angle comprised between zero degrees and the first angle.

A winding guide for an electric machine rotor, comprising:
- a base that is substantially circular about a longitudinal axis;
- teeth which extend radially from the base;
- and
- heads which extend at free ends of the teeth and which project from the teeth in cantilevered fashion,
- wherein at least one of said heads has an inner face which is turned towards the base and which comprises:
- a flat main portion that is inclined by a first angle strictly greater than 0 degrees with respect to the longitudinal axis, and
- ribs which protrude from the main portion, and vertices of the ribs are flat and inclined with respect to the longitudinal axis by a second angle comprised between zero degrees which is included and the first angle which is excluded.
