Electric motor

摘要

An electric motor has a rotatable armature having two pairs of poles, including a lamination stack which has a shape which is symmetrical about its axis and which forms twenty radial teeth and twenty slots and which has, associated therewith, a commutator with twenty segments, and a distributed closed winding, the conductors of which extend into the slots and are connected to the segments of the commutator in a predetermined manner. The winding of the armature has a lap-type winding or coil section connected to two adjacent segments of the commutator and, in series therewith, a plurality of wave-type winding sections or coils. All of these sections or coils encompass a same number of slots.

1. Direct-current electric motor having two pairs of poles, comprising a rotatable armature including a lamination stack which defines an even number of slots at least equal to eight and which has, associated therewith, a commutator with an even number of segments, and a distributed closed winding, the conductors of which extend into said slots and are connected to the segments of the commutator in a predetermined manner; and
wherein the winding of the armature comprises a lap-type winding section or coil connected to two adjacent segments of the commutator and, in series therewith, a plurality of wave-type winding sections or coils; all of said winding sections or coils encompassing a same number of slots; wherein the lamination stack of the armature has a shape which is symmetrical about its axis and has twenty radial teeth between which twenty slots are correspondingly defined, the commutator having twenty segments.
