Abstract

In an induction and universal motor combined in a common lamination stack and supplied from a single phase line in line with a single armature winding system common to universal commutator motor as well as to induction motor operation, there are connected to the same segments of the commutator a crossed lap winding and an uncrossed lap winding, the coil span of which corresponds approximately to one pole pitch of the low pole and, in particular, two pole commutator stator winding and to an uneven integral multiple of the high pole induction motor stator winding, to provide a motor particularly suited for driving automatic washing machines.
