ABSTRACT:
In an elevator system driven by a linear motor a small consistent air gap must be maintained between two elements of a linear motor for proper and efficient operation of the system. The air gap within the linear motor can be maintained and adjusted by utilizing a roller cam adjuster. The roller cam adjuster is disposed on a side of a moving portion of the linear motor and is supported by a plate with a roller disposed therein. As the roller cam adjuster is adjusted, the air gap can be either increased or decreased depending upon the need.
