Abstract
1,255,501. Motor casings. JOSEPH LUCAS (INDUSTRIES) Ltd. 13 Dec., 1968 [19 Jan., 1968], No. 2992/68. Heading H2A. An electric motor with a permanent magnet stator has a (metal) casing comprising two substantially cup-shaped parts 13, 14, one of which (14) has secured to it a sleeve 21 extending out of its open end to form a spigot for reception of the other, the stator magnets 20 being secured to the sleeve. The sleeve may be secured to the casing part 14 by rivets which also secure members 24 holding an insulating, brushsupporting plate 25. The magnets are held by spring clips 22. The armature shaft is supported in self-aligning bearings 15, 16, one of which includes springs 17 to permit limited axial movement of the shaft.
