ABSTRACT:
A method for assembling a stator for an electric machine having a permanent magnet for generating a magnetic field in an air gap. Assembly of the stator is performed with the aid of a plunger, the cross section of which corresponds to the cross section of the air gap. The permanent magnet is slid into the interior of the plunger, whereas the flux return ring is slid over the same. The so formed sub-assembly is put into a casting mold adapted to be filled with a plastic material, which in its cured or hardened state forms a casing intimately surrounding the outer surface of the flux return ring and forming a face plate, to which the permanent magnet adheres. When the plastic material has set, the casting mold is opened and the plunger is retracted from the sub-assembly, resulting in a close toleranced cylindrical air gap space. After insertion of a bell-shaped rotor, a brush cover is assembled opposite the face plate. The flux return ring may be longitudinally slotted and biased so as to more intimately contact the calibrated tube during assembly in order to reduce the air gap tolerances. Instead of a plastic casing, a cup-shaped casing of malleable or deformable material may be used.
