ABSTRACT:
A flat, single-sided linear motor driven elevator minimizes a moment on a primary element assembly towards a secondary element by aligning and balancing a center of gravity of the primary element assembly along the plane of an air gap between the primary and secondary elements of the linear motor. Ropes supporting the primary element assembly are attached thereto, and weights are positioned on a side of the plane, other than the side of the plane on which the primary element is disposed, to balance the centers of gravity and thrust of the primary assembly along the plane.
