An electric two motor drive is disclosed in which the field winding of a commutator motor having few poles and the stator winding, distributed in slots, of an induction motor having a larger number of poles are both arranged on a common stator lamination stack. The field winding is wound around part of the circumference of the stator lamination stack in the manner of a concentrated ring armature winding. Either a closed or an open stator lamination stack may be provided. The invention is applicable particularly to a two speed motor drive for an automatic washing machine having a single lamination stack for the series and induction motor windings. |
