Automotive technology, especially electric vehicles (EV), in the industrial era 4.0 is developing very quickly. Researchers continue to strive to improve performance on every component of electric vehicles including electric motors, batteries, and controllers. Permanent Magnet Synchronous Motor (PMSM) is a type of electric motor that is currently a concern because the rotor uses permanent magnets, and has a high power density. In this paper, the design and simulation of V-type Interior Permanent Magnet Synchronous Motor (IPMSM) is carried out, which is widely implemented in electric vehicles because it has a simple design and large power density value. In designing the motor, the V-angle shape of the magnet is arranged in such a way that it can produce optimal torque performance. The method used to adjust the V-angle magnet in order to obtain an optimal design is the trial and error method. This method is very easy to use in determining the optimal design, because it does not require a mathematical equation to solve it. Design modeling and performance simulation of IPMSM using finite element analysis (FEA) based software. IPMSM has 12 slots and 10 poles. FEA simulation results show that the optimal torque is at a V-angle of 95 mechanical degrees, which is 8.48 Nm. This motor can be a good consideration to be implemented, especially on electric vehicle.
