Abstract
1,090,937. Electric motors. RETOBOBINAHANDELSANSTALT. March 30, 1966 [April 1, 1965; Feb. 4, 1966], No. 14011/66. Heading H2A. [Also in Division B3] In a D.C. motor having a cup-shaped selfsupporting armature winding 22, the end loops 42 of the coils of the winding are secured to peripheral teeth 24 of a disc 23 which attaches the winding to the motor spindle 5. The teeth 24 may project into the air gap 15 further than the winding 22 so that the tips of the teeth form a fan for cooling. The teeth may contain single or multilayer windings and the windings may be of parallel or oblique, e.g. as in Specification 903,285, construction (Figs. 4 and 5, not shown). The flat disc 23 shown may be punched from a plate of synthetic insulating material. Alternatively the disc may be produced with inclined teeth (240) (Figs. 9-13, not shown), by moulding or press moulding of synthetic materials, e.g. a thermoplastic material. These inclined teeth may be heated and bent around the ends of the coils as at (241) (Fig. 13, not shown) to secure the winding. The motor has a field magnet 1 and return iron circuit 11 both of which may be replaced by an electrically energized system. Winding process.-The armature is made by winding the coils around the teeth of the disc and pins mounted on a mandrel of a coil winding machine. After the winding has been completed the pins and armature which is now secured to the disc are removed from the mandrel and can be impregnated or painted with an adhesive varnish to bond the various components together. Commutator and brush construction.-The commutator 9 (Fig. 1) is attached to a boss 27 formed on the insulating disc 23 and is contacted by brushes 10 secured to contacts 20. Also the segments 26, 29 (Fig. 2, not shown) can be embedded in the commutator body 28 or can be formed as printed circuits 38 (Fig. 6).
