Abstract
<div class="section abstract"><div class="htmlview paragraph">Electric vehicles (EV) require an electric motor with a better power density, greater efficiency, a wide constant power area, ease of control, and low costs. A real time control adapted electric motor design is necessary to meet these criteria. In this work, interior permanent magnet synchronous motor (IPMSM) design was created from Ansys rotating machine expert and 2D model was developed in Ansys Maxwell based on various design parameters for the rotor and stator configuration, and the electromagnetic (EM) simulations are carried out in accordance with the essential required EV characteristics. Using Ansys Twin Builder, a model was made for the drive circuit, proportional integral (PI) speed controller, speed references, rotor position detection, and space vector pulse width modulation (SVPWM) / sinusoidal pulse width modulation (SPWM) are used. This method demonstrates the investigation of the torque ripple and total hormonic distortion (THD) and shows the influence of SVPWM and SPWM techniques on torque ripple and THD. To realistically reflect the performance of the drive, coupled simulation of the IPMSM motor and drive with vector control system is used to analyze the IPMSM drive system through Ansys maxwell and Ansys Twin Builder environment during EM analysis. The simulation outcomes demonstrate the high feasibility of motor design and control strategy, that delivers the intended result and quick response with minimal torque ripple and distortion. According to the simulation findings at 10kHz, SVPWM technique has torque ripple 12.4% and THD in the input current and voltage to the motor are 4.0 and 38.4% respectively. But SPWM has torque ripple 28.5% and input current and voltage THD are 6.8 and 42.6% respectively. Investigation shows SVPWM method is more practical and effective for producing sine waves that deliver higher voltage and current to the load with minimal torque ripple and harmonic distortion.</div></div>
