Permanent magnet synchronous motors (PMSM) are generally known for their type whose magnets are located on the rotor surface and this motor type, which is called surface mounted permanent magnet synchronous motors (SPM), produces magnet based torque. Based on torque equations, since there is only q-axis current and value of magnetic flux linkage, the d-axis current is kept at 0 and the torque is maximized and controlled, which is called 𝐼 𝑑 = 0 control technique. However, reluctance torque is produced in interior mounted permanent magnet synchronous motors (IPM) due to the inductance difference caused by the saliency in the rotors and by controlling the reluctance torque correctly, the efficiency of motor increases. For this reason, maximum torque per ampere (MTPA) strategy is applied to perform torque control efficiently in IPMs. In this study, the difference between the efficiency values was observed by simulating torque control in IPMs with the MTPA strategy instead of the conventionally used 𝐼 𝑑 = 0 control technique. As a result of the simulations, using the MTPA strategy instead of the conventional vector control technique in the drivers of the IPMs used in electric vehicle applications increases the efficiency of the system and extends drive range capacity by using the battery more efficiently.

Permanent magnet synchronous motors (PMSM) can be classified into two groups based on the rotor saliency structure as surface mounted permanent magnet synchronous motors (SPM) and interior mounted permanent magnet synchronous motors (IPM). Saliency ratio is defined as the ratio of q-axis inductance to d-axis inductance. While SPMs with the same d-and qaxis inductance values have the capacity to generate only the magnet-based torque IPMs are salient machines and they also produce reluctance torque due to the difference in inductances. This study analyses the influence of the saliency ratio on the drive system efficiency and the torque production capability of salient machines. First, efficient torque control systems have been implemented and successfully achieved for two identical IPMs with only difference in saliency ratios. Then, tests were carried out on the drive systems for two IPMs. It has been validated by extensive simulation results that the torque production capacity and the efficiency of the drive system can be increased considerably if the saliency ratio can be increased at the stage of machine design.
