Abstract
Line start permanent magnet synchronous motors (LS-PMSM) are preferred more and more in industrial applications, because they can start on their own and because of their high efficiency. In this study, a new LS-PMSM rotor typology is suggested, which is modelled using surface mount permanent magnets, in which two different slot types have been used together. The rotor of an asynchronous motor on the industrial market in the IE2 efficiency segment has been remodeled in the study, resulting in an increase in motor efficiency from 85% to 91.8%. A finite elements software was used for determining motor design and performance, in addition to analytical methods.

Electrical motors have the highest share in electrical consumption for industrial and home applications
Many regulations are ongoing regarding the frame dimensions, operating characteristics, and operating conditions for these electrical motors, which are put on the market with standards that are accepted by electrical motor producers [4]

Summary
Electrical motors have the highest share in electrical consumption for industrial and home applications. Electronics 2019, 8, 25 to decrease every day [8] These motors with a permanent magnet in their rotor and an IM squirrel cage are known in the literature as line start permanent magnet synchronous motors (LS-PMSM). IMs, with which generate variable subject load, they continues tocage decrease every day [8] These to motors a permanent magnet rpm in their rotorto and an IM cansquirrel continue to operate at ain constant speed after reaching a synchronous speed. While the may start asynchronously viato direct powerthe from the line, like IMs, because flux generated byLS-PMSM the permanent magnets, which leads reducing electromagnetic losses on the of the squirrel cage in their rotors, contrary to IMs, which generate variable rpm subject to load, they rotor to an almost non-existing level (when harmonics are considered) [10,11]. The T and T torque components generated at n o the time of starting are expressed pbymEquations (1) and (2), respectively [12,13,14]
