Abstract
The transmission comprises at least three induction systems which are arranged axially one after the other or coaxially one above the other and which can be rotated about a common axis of rotation (,). The induction system in the middle is in each case provided in the side faces with a winding which are connected to one another and are executed in such a manner that the magnetic rotary fields which arise by means of relative movement between the induction system in the middle and one adjacent induction system effect a relative movement between the induction system in the middle and the other adjacent induction system in order to produce an output movement.
