| Abstract |
This paper presents a simple electronic starter for single phase induction motor (SPIM). It replaces the centrifugal switch in the auxiliary winding circuit of the capacitor start type SPIM. The electronic starter observes the auxiliary winding voltage, and disconnects the auxiliary winding when the motor gets close to its rated speed. Because of its possibly fluttering contacts of the centrifugal switch which mounted on the conventional SPIM, the reliability of SPIM can be reduced. Developed new electronic starter has no mechanical contacts. Therefore, the reliability and the performance of SPIM can be improved. The operational principle of the proposed electronic starter is explained, and illustrated with experimental results. |
