Decoupling and adjustment of forces in an electromagnetic guiding system with six degrees of freedom

Abstract

Purpose

The purpose of this paper is to describe the derivation of an adjustment directive for the non‐linear and coupled forces of a high‐comfort elevator guiding system based on so‐called electromagnetic ω‐actuators.

Design/methodology/approach

The derivation of the adjustment directive contains a coordinate transformation from local forces and torques to global quantities.

Findings

It is demonstrated that the derived system is able to operate the guiding system of the elevator car. Measurement results show a well running system in face of several mutual influences on the actuating forces.

Practical implications

The results presented offer the opportunity to increase the riding comfort and decrease the deterioration of high‐speed elevator systems. It is possible to apply the proposed system to ropeless elevators and to conventional elevator systems as well.

Originality/value

The methods developed and proved in this paper grant an effective way to control magnetically levitated systems with complex actuator topologies.
