be used to drive the washing drum of an automatic washing machine could be provided with 12 poles and with the utilization of a reduction belt drive would be able to rotate the drum of the washing machine at approximately 50 rpm 39 s the induction motor can also be provided with only two phase windings instead of the three phase windings shown in fig1 according to a preferred embodiment the universal motor has two poles although a different number of poles could be selected the number of poles of the universal motor should however differ from the number of poles of the induction motor since by virtue of this difference one obtains without additional switching and interrupting means in the current supply to the induction motor no overall oversynchronous braking torque of the induction motor when the commutator series motor is operated at a speed above the synchronous speed of the induction motor the upper portion of fig2 depicts the winding plan of the prior art induction stator winding generally shown in fig1 the upper portion of fig2 shows the core of a 12 pole 3 phase winding induction motor 1 while the lower portion of fig2 shows the winding plan of the stator of the 2 pole universal motor arranged on the same lamination core the winding as shown in fig2 consisting of these two winding configurations would be appropriate for the stator of a motor constructed according to the teachings of this invention fig3 shows a first phase winding which is not connected to the commutator of a rotor winding having 2 phase windings which function in induction motor operation the second phase winding of this rotor winding is shown in fig4 with the brushes carrying.
