"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."
