Abstract

1281992 Linear motor conveyers NATIONAL RESEARCH DEVELOPMENT CORP 10 Dec 1969 [31 Oct 1968] 51739/68 Heading B8A [Also in Division H2] An electric motor comprises a primary member with a polyphase A.C. winding and a secondary member having a plurality of separate, spaced apart magnetic elements which are free to roll about their own axes over the surface of the primary member. Preferably the elements are steered relative to the travelling magnetic field and they may be surrounded by conductive material. Fig. 2 shows a linear version of the motor applied to a conveyer. The stator 10 carries the A.C. winding 11 in skewed slots and has a thin layer 12 of nylon on its upper surface on which the steel rods 13 roll. The rods are loosely held between teeth 17 formed on the links of a pair of side chains 14 forming the conveyer belt. A package 19 can be carried on the chains, on pivots 16 which extend from one chain to the other or directly on the rods 13.
