Abstract：Based on the measurement principles of the direct and quadrature axis inductances of synchronous reluctance motor with direct load method. The paper proposes a method to measure intersection angle between synthesizing voltage vectors and rotor d axis with photoelectric encoder and then to calculate direct and quadrature axis inductances value in combination with the relative equations. The method has relative high precision of measurement for direct and quadrature axis inductances of synchronous reluctance motor. The experiment for the direct and quadrature axis inductances values of the prototype under the different loads is made. Test results are compared with the values of finite element simulation of the same motor and results are identical, so the method is proved to be feasible and precise.
