Electrical machine e.g. direct current motor, for wiper drive of windscreen wiper, has grooves extending in longitudinal direction of machine and pole shoe with diagonal course, where grooves are arranged parallel to longitudinal direction

摘要

The machine (2) has a support for four poles having pole shoes (16), extending in a longitudinal direction (13) of the machine, and an armature (5) provided with grooves for retaining armature windings, where the grooves extend in the longitudinal direction. The pole shoe has a diagonal course, where the grooves are arranged parallel to the longitudinal direction. The pole shoes are formed as cylindrical segments with diagonal pole shoe edges (17), where the poles have permanent magnets (15).
