The early inventors and their patents



Linear motion is common in Nature and in the motions of early steam, gas and other internal combustion engines. In the mechanical devices the ‘natural’ linear motion is converted to rotation by other mechanical means. The history of linear electrical machines is concerned with the influence of such reciprocating machines only to the same extent as that to which rotary electric motors left their mark, as discussed in chanter 1.
