Abstract
This chapter is dedicated to an algorithm of approximate calculations of
three-phase induction motor equivalent T-shaped circuit parameters such as resistances
and inductances. These calculations are conducted with the use of catalog or reference
book data containing information related to rated shaft power, angular speed or slip,
efficiency, power factor, line RMS voltage and the ratio of starting to rated currents.
Keywords: Parameters of induction motor, Per phase T-shaped equivalent circuit.
