ABSTRACT:
In an electric motor comprising a U-shaped laminated stator core, whose two limbs each carry an exciter winding, a rotor mounted on a motor shaft, and two bearing shields, one bearing shield is provided with at least three sword-shaped projections, of which at least two projections enclose the outer sides of the two limbs of the laminated stator core and of which a third projection is arranged between the two limbs of the laminated stator core, the last-mentioned projection being provided with a T-shaped member, whose transverse limb is positioned against the yoke of the laminated stator core from the inner side. The other bearing shield is formed with openings through which the free ends of the projections extend and can be secured from the outer side of this bearing shield.
