Abstract：The operating characteristics of a three-phase induction motor are generally tested by load ex-periment, but this method is only suitable for small and medium sized case .For large sized three-phase induction motor , its operating characteristics on the spot are difficult to test , so an analytical method is proposed in this paper .In order to meet the need of engineering application , the simplified equivalent cir-cuit of three-phase induction motor is analyzed , and the analytical formulas of the operation characteris-tics are derived .By using the derived analytical formulas , the operating characteristics under rated condi-tions are analyzed ,and the calculation results are consistent with the design values ,which verify the cor-rectness and accuracy of the analytical formulas .The advantage of this method is that it can conveniently analyze the operating characteristics of three-phase induction motor under various operating conditions , and its operating characteristic curves can be drawn out easily by using Matlab software .
