ABSTRACT:
A linear induction motor for opening and closing elevator car doors in an elevator system includes a motor primary fixedly attached to a door hanger and a motor secondary flexibly mounted to a header bracket of the elevator car. A pair of swivel joints secure the ends of the motor secondary to the header bracket. The swivel joints compensate for misalignment and twisting of the elevator car doors by allowing multi-dimensional movement of the motor secondary relative to the header bracket.
