LINEAR DRIVES: PRESENT DEVELOPMENT AND OUTLOOK

There are three basic types of electric machine: direct-current, synchronous and asynchronous. Of these, certain versions can be employed as linear motors. The article deals with the d.c. linear motor, the linear asynchronous and synchronous motor as short-stator drive. The aspect of cost for the substantial machine element on the track side is of importance in arriving at suitable linear motor variants. Another important consideration is the regulating unit owning to the substantial role of the power electronics in the drive concept. Also described and evaluated are the linear motor as long-stator drive with integrated support function and the non-ferric synchronous long-stator drive. The exhibit featuring the long-stator drive with integrated support function at the IVA in 1979 showed the basic suitability of the technique although only limited train speeds were permitted there. The concept will be tested at speeds of up to 400 km/h in 1982 on an experimental track in Emsland in North Germany.
