Abstract
This paper shows a high-performance sensorless driver for an induction machine with a Scott-T connection in the stator windings.This connection is used to transform a single-phase machine into a three-phase only by changing the winding configuration, increasing efficiencyand minimizing the cost impact. This type of solution can be used as an alternative to the use of highperformance drivers controlling single-phaseinduction machines. The motor model using the Scott-T connection is developed and the experimental results of a vector control approach by fieldorientation are shown. A sliding mode observer is also developed for estimating the speed of the machine tested.
