Abstract :
A classical method for angular position and speed estimation in adjustable speed drives uses an incremental shaft encoder and an electronic circuit. This paper presents SLESS, a tachometer without a mechanical transducer implemented on an ASIC using sensorless speed estimation techniques. The ASIC is intended to serve as part of an integrated solution developed for fuzzy speed regulation and vector control of induction motors
