Electrical drive e.g. cylindrical linear induction motor, for body training equipment, has cylindrical secondary sections that move against stator for providing magnetic field that is symmetrical in rotation, to stator
The drive has a stator, and a number of cylindrical secondary sections that are placed in the stator as a sleeve bearing. The cylindrical sections move against the stator, so as to provide a magnetic field that is symmetrical in rotation, to the stator. The sections include a non-magnetic tube in which permanent magnets are disposed. The non-magnetic tube has a metallic sliding layer on its outer side.
