ABSTRACT:
An electric motor comprises bracket shaped end plates having extensions that lead directly to the stator and are connected to the stator by introducing the extensions into grooves. The motor includes a layered arrangement of components on the collector-side, comprising a carrier plate with a punched grid pattern forming the electric wiring. The grid pattern, together with the carrier plate, carry brush holders. Next in the axial direction is a switching ring bridging preselected line connections of the grid pattern by means of short circuiting bridges, and which is rotatably seated in a central recess of a mounting plate provided on the end plate. All connections can be fabricated by simple pressing and plugging and the motor is suited for fully automatic assembly operations.
