Abstract

463,813. Magnetos. BRITISH THOMSON - HOUSTON CO., Ltd., and GRIFFITHS, L. Nov. 28, 1935, No. 33040. [Class 35] A magneto rotor comprises bar magnets of high coercive force material abutting longitudinal flats on the shaft and extending radially to polepieces of alternate polarity, the magnets and pole-pieces being secured by end plates secured to the shaft. In the form shown, magnets 2 bear on the flattened portions of tapered shaft 1 and are forced against the left-hand end ring 5 by grub screws, an insertion of resilient material 8 being provided as shown. The magnets are also secured by the laminated .pole-pieces 3 held between end rings 5 by rivets 4 and a non-magnetic reinforcing ring 6 may be provided. In a modification, the shaft is not tapered and the grub screws are omitted.
