Abstract To control the torque of the IPMSM, a lookup table is generally used in control system because of its nonlinear characteristics. However, the method of generating the lookup table data has the disadvantage of having difficulty accurately analyzing the changing parameters, generating the current or magnetic flux map is complicated and long test time taken due to motor temperature differences at each test points. In this paper, on the basis of the electromagnetic field design of IPMSM, we devised an electromagnetic field-based magnetic flux map model that can compensate for the pre-generated magnetic flux map through a quick and simple test.
