ABSTRACT:
A linear motor elevator system includes a car mechanically coupled to a counterweight assembly such that the car roping ratio is less than the counterweight assembly roping ratio. A primary element of the linear motor is disposed on or within a hoistway wall associated with the secondary element of the linear motor. Alternatively, the primary element is affixed to a support frame of the elevator system. The counterweight assembly includes the motor secondary. The elevator system of the present invention reduces the volume within the hoistway interior occupied by the primary and secondary members of the linear motor.
