Abstract

The present invention relates to an electric motor having a winding support (9) for the windings of the motor stator. The winding support is formed with a cylindrical coaxial space having a first end (16) which is at least partially closed and a second end (14) which is open. A plurality of regularly spaced bars (10) are formed on said winding support (9). Certain of the bars, preferably alternate ones of the bars, are formed with an elongated, outwardly extending projection, adapted for placement thereon of a generally oval winding of the motor stator. Preferably, the partially closed first end (16) has a central opening, into which a bearing (7) for the rotor shaft (4) or a stepped end of a split bell can be inserted.
