Abstract


Dynamic and static AC electric machines can be modeled with equivalent circuits for the purpose of analyzing the characteristics of dynamic and static AC electric machines after their parameter values are known. Methodology to determine the value of equivalent circuit parameters by carrying out no-load testing and short circuit testing. There is a difference in value between dynamic and static AC electric machines with the prototype. The difference in the torque speed curve of the AC electrical engine with a prototype induction electric motor 1,1 kW type squirrel cage rotor, namely Tstart = 0,6 Nm, Ts-max = - 0,23 and Tmax = 3,1N.m, and factors work of static AC electrical machines with 5kVA transformer prototypes, namely pf 0.75 and pf 0.65 in terms of the working voltage side of the secondary coil, namely 1.7V and -1.4 V.
