3 PHASE AC MOTOR STARTING METHODS:
A Detailed Analysis of Various Methods of Starting an AC Induction Motor and Their Effects on Motor Characteristics.


Thomas Blair, P.E., Phasetronics/Motortronics, Clearwater, Florida

This paper will explain basic AC induction motor theory and then apply this theory to describe motor characteristics during starting.




Then this paper discusses the effects soft starting an AC motor has on these various characteristics. Lastly, this paper briefly reviews various methods of soft starting an AC motor and discusses some of the advantages and disadvantages of each of these methods.
