The legacy of rotary machine design can be seen, in part, as an inhibition of linear motor experimentation, even as far as the 1970s. In rotary machines, the tangential direction was the thrust direction and the axial direction was simply a means of increasing power output. Three-dimensional thinking was, in some ways, more advanced in the Victorian era... the Second Age of Topology can be seen as having had its beginnings in the demand for high-speed propulsion, the problem of the long pole pitch and the resulting development of the TFM concept.

About Eric Laithwaite

Eric Roberts Laithwaite (14 June 1921 – 27 November 1997) was a British electrical engineer, known as the "Father of " for his development of the and maglev rail system. He and Fredrick Eastham designed a self-stable magnetic levitation system called (which incidentally appeared in the film The Spy Who Loved Me). Laithwaite derived an equation for "goodness", which parametrically described motor efficiency in general terms, and which he interpreted as implying that motor efficiency increases with size. He made many television appearances, including the to young people in 1966 and 1974. Laithwaite was also a keen amateur entomologist and the co-authored The Dictionary of Butterflies and Moths (1975).

Additional quotes by Eric Laithwaite

The research director of Linear Motors Ltd told me in the late 1970s that he had then listed over one thousand different applications for linear motors. By this he meant that motors had been manufactured and sold for that number of different jobs. The most common applications included sliding doors, traveling cranes and conveyors. The items that were moved varied from 0.1 mg... to over 5 tonnes.

I know no property of a gyroscope that conflicts... with the conservation of energy. ... is in the same state today that as it was in the fifteenth century when Leonardo da Vinci denounced it so properly. ...If you really want to see perpetual motion, look into the sky on a cloudless night and marvel at the size and movement within the Universe.

I make most of my inventions when I'm talking to other people. ...I drag them from their interest into mine, and then they thank me when they leave, and I feel as if I should pay them a fee, because I feel as if I've used their brain to sort of reflect from.
