Abstract

407,533. Motors. ELECTROFAN GES., 113, Reinickendorferstrasse, Berlin. March 23, 1933, No. 8856. Convention date, Feb. 13. [Class 35.] Pole-pieces ;brush-holders , commutators.- The stationary member of a low power commutator motor comprises a pair of end covers of insulating material connected together by a pair of segmental pole-shoes secured to a slotted tubular permanent magnet. In the form shown, the pole-pieces 2 are separated except at their margin from the magnet 1 by non. magnetic material 35 and have projections at each end which fit into corresponding slots in the end brackets 6, 7 which may also be connected by a water-tight cover 36. The armature pole-shoes 18 have axial slots to fit over the extensions 15 of the laminµ 12 and the commutator comprises four bars 22 held in turn by rings 23, 24 of insulation and metal respectively. A pair of strip metal brushes 25, 26 is rotatably mounted on each of terminals 27, 28 on the bracket 7 with spacing discs 34. Specification 407,532 is referred to.
