Abstract

Nowadays, many researchers focus on the use of clean energy instead of fossil fuels. The utilization of electric vehicles (EVs), in addition to reducing fuel consumption and associated costs and minimizing environmental pollution, allows for the recovery of a significant amount of energy during the braking mode. Another crucial advantage is the reduction of noise emissions when using EVs. The selection of an efficient electric motor with high power plays a vital role in EV applications. Also, the modeling process is growing more complicated as the need for greater efficiency, higher power density, and lower costs drives motors toward higher speeds and more compact designs. Consequently, interactions across multiple physical domains (such as electromagnetic, thermal, and structural) must now be considered, even during the early stages of design. In this paper, a design algorithm is introduced for the delta-shaped interior permanent magnet synchronous motor (IPMSM), facilitating the completion of the motor's initial design. The design optimization of this type of IPMSM for EV application is also considered. The motor's performance, demagnetization, mechanical stress, and thermal performance are evaluated using the finite element method (FEM). Based on the optimized design criteria, a suitable design can be chosen from the best set of designs obtained.
