Abstract

470,944. Commutators for dynamo - electric machines. SIEMENS-SCHUCKERTWERKE AKT.-GES. Aug. 21, 1936, Nos. 23050, 23051, and 23052. Convention dates, Aug. 21, 1935, April 29, 1936, and July 15, 1936. [Class 35] A commutator is formed by moulding insulation about mica insulated segments anc reinforcing metal rings are inserted in the ends of the mouldec body with limbs extending parallel and perpendicular to the commutator axis, the limbs parallel to the axis supporting the commutator and reinforcing the anchorage of the segments in the body. In the form shown, the segments 21 are insulated with mica (not shown) and reinforcing metal rings 24a, 24b are inserted in the moulded hub 23. The rings may initially be in one piece as in Fig. 3, the raised portion being subsequently machined off to provide two rings or a ring of channel section may be used without alteration. Axial cooling ducts may be provided in the hub and rings and fan blades may be moulded with the hub if desired.
