Performance analysis of single-phase induction motor based on voltage source complex finite-element analysis

In this paper, to make a compromise between accuracy and efficiency in the design of single-phase induction motors, voltage source complex finite-element model, which is combined with the equivalent circuit method to carry out the performance analysis, is presented. The voltage source complex finite-element method is used to determine equivalent circuit parameters by simulating the no-load tests and locked-rotor tests, while the conventional method is adopted to calculate the performances. Good agreement is achieved between the calculated results and test results, which verifies the effectiveness of the presented method.
