FIELD: transmission of rotary motion to interior of any enclosed space in any industry. SUBSTANCE: satellite spur gear 2 rolls over inner surface of cylindrical case 1 made of nonmagnetic material; at least one annular part 3 of satellite gear 2 is made of magnetic material; satellite gear 2 is set in movement by means of device installed outside drive to build up magnetic field revolving concentrically in respect to case 1. Permanent magnets 5 are installed outside concentrically in respect to case. EFFECT: improved design. 3 dwg
