چکیده
The trend towards the adoption of direct drive washing machines utilizing PM motors is increasing due to the mechanical simplicity, high performance and efficiency of the system. This work deals with design and performance of a sensorless PM motor drive for washing machines. An implicit rotor position detection unit which consists of groups of search coils are inserted into the motor stator. A simple neuro-fuzzy controller has been used. The results given in this paper demonstrate the capability of such a drive system in washing machine applications where simplicity, reliability and stability are more important issues.
