Elevator control system featuring all-electromagnet vibration and centering elevator car controller for coupling a roller arranged on a pivot arm to a guide rail

摘要

An elevator control system has a roller guide assembly comprising a plurality of rollers arranged in a cluster having at least one roller connected thereto for coupling an elevator car to a guide rail mounted on an elevator hoistway wall. The roller guide assembly comprises a pivot arm for pivoting on a horizontal pivot axis in relation to a longitudinal axis of the guide rail. The elevator control system features one or more electromagnet actuators for providing both vibration and centering control and without any solenoid for providing centering control.
