Linear motors for Multi Mobile Systems

In large cities, due to expensive land price, high-rise buildings are built, in which the space dedicated to the elevators is considerable and reduces the rented surfaces. To decrease these lost surfaces, a Multi Mobile System is proposed: it consists of several moving cabins in the same shafts permitting also horizontal motions. In this case, the use of direct linear motor drives without counterweight is requested. But it implies high mechanical power and energy consumption. A system design optimization permits to obtain a positive return of investment. This paper focuses on linear motors to move the cabins. Multi criteria system and motor designs are presented. Finally, the economical balance emphases the interest of Multi Mobile Systems.
