Abstract

988,891. Commutating pole constructions. SIEMENS-SCHUCKERTWERKE A.G. Aug. 7, 1962 [Aug. 7, 1961], No. 30266/62. Heading H2A. A D.C. dynamoelectric machine whose excitation field varies substantially due to either variations in loading of the machine or feeding the machine with pulsating direct current, comprises a massive stator ring 11 provided with laminated commutating poles 17 and laminated main poles 12 having commutating field bridges 15 which provide a low magnetic reluctance path for the commutating pole flux (shown by broken lines) and include non- magnetic gaps which create high magnetic reluctance paths between the main poles, the bridges and commutating poles being separated from the ring 11 by non-magnetic gaps 16. The commutating pole may have a radially extending non-magnetic gap 19, and the gaps may be wholly or partly filled with electrically conductive material. The main pole core 14 is divided to aid the mounting of a main exciter winding 13.
