Abstract
A rotor for a small electric motor, useful for example in a vehicle window raising device, has an armature carried by a shaft and having slots in which electrical conductors are wound and connected to a current collector. The shaft has grooves at both ends of the armature to a depth such as to permit the path of the electrical conductors passing between non-consecutive generally opposed slots during winding of the conductors at the bottom of the armature slots to be substantially rectilinear.
