Abstract: EV's are eco-friendly automobiles. Electric vehicles are powered, driven and propelled by electric motors, unlike traditional fossil fuel-driven IC engines. The electric motor derives energy from rechargeable batteries and fuel cells (Kumara, 2017). The performance of the electric motors used in EV's must be increased by conducting different analysis (Sandeep, 2019). This work provides stability analysis of PMBLDC motor. This project aims at increasing efficiency of PMBLDC motors contributing in R&D section of EV industry. Finite element analysis (FEA) of 48V and 72V PMBLDC motor is used to compare the torque, speed, power and efficiency of the motor (Fasil et al., 2016). The results prove that 72V PMBLDC motor has superior characteristics suiting the need of electric scooter application. By replacing the electrical components of 48V PMBLDC motor with 72V PMBLDC in the same housing of 48V motor, the results obtained with stability analysis is expected to be better than 48V PMBLDC motor.
