ELECTROMAGNETICALLY DRIVEN AUTOMOTIVE SLIDING DOOR

摘要

An electromagnetic system for a powered vehicle door for driving the door forward and/or backward between open and closed positions is provided. The electromagnetically driven sliding door includes a door panel with at least one permanent first magnet fixed to the door panel. A plurality of electromagnetic coils are operably mounted adjacent the door panel. The electromagnetic coils are configured in electrical communication with a source of electric current of alternating first and second polarities. The electromagnetic coils are energizable via the electric current to attract the at least one first permanent magnet in response to the first polarity electric current and to repel the at least one first permanent magnet in response to the second polarity electric current to drive the door panel between open and closed positions. Permanent pole magnets can be incorporated to facilitate supporting the door within a door track of the door.
