Abstract
This paper presents an improved analysis of magnetic force compensation in a bearingless induction motor with a squirrel cage rotor. The expressions for rotor flux linkage are derived. Simulation blocks of suspension force are constructed. A novel control system, which compensates the delay and direction error in suspension force generation for a squirrel cage rotor is proposed. The efficacy of the proposed control system is established by both simulation and experiment.
