Abstract

140,693. Clifford of Chudleigh, W. H. Clifford, Baron. Aug. 27, 1919. Motors, controlling; cores; armatures and field magnets, cooling.-A motor suitable for driving machine tools comprises a cylindrical casing 1 and end caps 2, 3 carrying the rotor bearings, one of the caps carrying two insulated rings 16, 17; the ring 16 is fixed and carries the field connexions 19, while the ring 17 is rockable by means of a handle 27 and carries the brushes 21 and their contacts, which are adapted to be brought into contact with different field contacts 19 to reverse or regulate the machine. The rotor shaft carries a fan 8, and air ducts are provided at 14 through the rotor and also by the corrugations on the periphery of the stator laminations shown in Fig. 2 registering with grooves in the casing 1. The stator slots are inclined with respect to the rotor axis in known manner, while the rotor slots are parallel to the axis, whereby starting the machine is facilitated. It is stated that the machine is equally operable by direct and alternating current.
