The three phase induction motors are most widely used for electric drive applications due to its simple, rugged construction and easy maintenance. Induction motors are considered as workhorse of the industry. This paper presents an experimental investigation of load characteristics along with equivalent circuit parameters of three-phase induction motor drive. The dynamic mathematical model of the machine under different reference frames is analysed with the parameters of the motor obtained through experiments. The equivalent circuit model under steady state is developed; performance of the induction motor is determined form the developed equivalent circuit and the results obtained are verified using the dynamic model under different reference frames. A 5 hp induction motor is used for the experimental verification.
