Abstract

The estimation of rotor position is fundamental for the commissioning of magnetically-levitated drives. The sensors required for this measurement must be close to the rotor, often requiring constructive measures that may limit the application potential of a drive. This publication presents the estimation of rotor angle and position, based on Hall-effect sensors installed on a slotless bearingless drive. This scheme enables sensor mounting away from the rotor, thus simplifying its encapsulation.
