  • Patent number: 4221999
    Abstract: A three-phase motor is wound with three spaced phase windings each having first and second multiple section windings. The second winding sections of each are connected in series. The first winding has one end of all three phases connected in common. The second winding has one end connected to the common intermediate connection of the first winding sections. The outer ends of the windings are connected to a two-speed switch having two different positions for alternate direct connection of the two windings to incoming phase lines. In one position, both sections are in circuit with the three oppposite ends of the one winding connected to each other to form a second common connection. In second position, the second windings is disconnected and the first winding sections are connected in series in a star circuit, with the current flow in the two sections of each winding reversed from the first speed connection.
