摘要： A supporting member is fixed to the moving element of a toroidal type linear motor, the support member being maintained a predetermined distance from a stationary element to maintain a predetermined annular air gap between the stationary and moving member. The supporting member may comprise a plurality of rollers which are rotatably provided on the top and bottom of the moving element, the rollers being so arranged as to be radially spaced from the stationary element. The distance between the rollers and the stationary element is less than the distance between the stationary and moving elements.

摘要： An elastic body is provided upon a moveable element of a linear motor, the elastic body in sliding contact with the surface of a stationary element of the linear motor, the elastic body maintaining a predetermined minimum air gap between the moving and stationary elements. A sweeping material is attached upon a portion of the elastic body which contacts the stationary element. Preferably the sweeping material is a woven or non-woven fabric, such as felt or the like.

摘要： An apparatus for maintaining an air gap between a stationary and a moving element of a toroidal linear motor which provides motive force to an elevator, comprises; a plurality of rollers mounted upon the moving element, and a means for biasing the rollers towards a central axis of the stationary element, and for cooperating with the rollers to maintain the air gap when power to the motor is shut off or vibration or other forces would tend to lessen the gap below a predetermined minimum. The rollers are arranged angularly about the stationary element and rotate due to the relative rotation of the moving and stationary elements.

摘要： The suspension system for an elevator car provides ropes that converge on the car close to a vertical line containing the center of gravity of the car. The ropes thus impart very little lateral or torsional movement to the car whereby a smoother ride results. The ropes are mounted on a set of sheaves which are arranged in a V-shaped array. The ropes thus fed to the counterweight are spread farther apart than those fed from the sheaves to the car.

摘要： A stator member of a linear motor type elevator system is mounted in the elevator hoistway so as to permit vibrational movement of the stator to occur. The stator mounts permit rotational movement of the stator and also apply a longitudinal tensioning force to the stator. The tensioning force is supplied by a spring which absorbs vibrations of the stator.

摘要： A rotary encoder engages the circumferential periphery of an elevator sheave to monitor the rotational speed of the sheave. The encoder is mounted on an adjustable mounting assembly which biases the rotor against the sheave circumference along a line passing through the axis of rotation of the sheave.
