The original Ames/Gold King plant is also notable for the small starter motor used, an early use of an induction motor, a new efficient commutator-less design that would later become common place. The patent for the motor had been licensed by Westinghouse from Nikola Tesla two years earlier and was being developed by Charles F. Scott, but engineering problems and the general shortage of cash the company was going through was holding back development. Westinghouse eventually introduced their "Tesla" poly-phase transmission/motor system in 1893.
