    Linear motors are used for special purposes in linear direct drives. In many cases direct drives offer some advantages, such as better dynamics, higher accuracy and lower price. To make advantage of ... the new technology for motion at extreme line velocity and line accuracy requests, numerical control of motion is needed. Such linear direct drives are practical for processes with limited charge forces, e.g. machining centres, laser working, beam cutting and cutting out. A linear induction motor with a short primary is described. It was calculated with CAD and the given data for a standard rotary motor with a fourty-five times greater number of poles than a five-pole real motor has. The motor is almost flat. In addition, the layout scheme of the measurement equipment is presented. The force measurement parameters in the controller are configurated with a card produced by Indramat and integrated in a PC. The results of test values for force measurements and heating of the two different primaries and the same secondary are shown. The force pulsation measurement results were obtained in a special way at a 60 Hz supply voltage.
