Abstract
Identifying Three Phase Induction Motor Equivalent Circuit Parameters from Nameplate Data by Different Analytical Methods
Highlights
The induction motor equivalent circuit parameters are usually computed from DC, no load, and blocked rotor test data as per IEEE Standard 112
The dc, no-load and blocked rotor tests simulation models are developed by using MATLAB/Simulink
The first method from the paper was employed in MATLAB environment and model simulations were carried out
Summary
The induction motor equivalent circuit parameters are usually computed from DC, no load, and blocked rotor test data as per IEEE Standard 112. The dc, no-load and blocked rotor tests simulation models are developed by using MATLAB/Simulink Another novel technique is proposed to estimate performance characteristics from motor parameters and manufacturer’s data. No-Load Test The no-load test on an induction motor is conducted to measure the rotational losses of the motor and to determine some of its equivalent circuit parameters (Rc, Xm) In this test, the stator terminals are supplied by balanced voltages at the rated frequency with the rotor uncoupled from any mechanical load.
