System for contact free motion of a plate such as rotation of a plate of a record player, comprises magnetic field generating system integrated in base of frame

摘要

The system includes the body or plate to be rotated. One or more magnets, magnetic components and/or magnetic field generating systems (2) are integrated in the plate (1) so that there is predominantly one pole direction to the axis of rotation. The system also includes a frame (42) within which the plate is mounted. One or more magnets and/or magnetic field generating systems (4) are integrated in the base of the frame. A frame (31) also runs around the plate and one or more magnets and/or magnetic field generating systems (3) are integrated in this frame forming a ring around the plate. The pole direction of the plate and that of the frame (31) at the end have the same polarity.
