Effect of Airgap Flux Regulation on Interior Permanent Magnet Synchronous Motor
Subject area: Science,Engineering and Technology · Area of research: Electrical Machine and Drives
Abstract
Permanent magnet synchronous motors (PMSMs) as AC machines are mostly preferred to other AC machines for applications in industries and other household appliances due to their high efficiency, high power density, high torque-to-inertia ratio, high dynamic response, simpler structure, better heat radiation capacity etc. In this study, an algorithm was developed to control the speed and torque of an interior permanent magnet synchronous motor (IPMSM) by regulating the airgap flux. A salient pole interior permanent magnet synchronous motor (IPMSM) drive powered by a Vdc source and incorporating a three-phase inverter (VSI) controlled by PWM, an electrical motor, a vector controller and a speed controller was modelled using MATLAB/Simulink 2021a version. The airgap flux was adjusted at an interval of 0.0005 Wb to assess the machine?s performance such as speed, torque and mechanical power from the simulated results obtained. It was obvious from the results that the motor was improved by 64.12 % electromagnetic torque, 36.12 %, 25.9 % and 36.12 % mechanical power, efficiency and power density respectively. These features of the motor make it suitable for application in electric vehicles, home appliances, robotics and automation, medical devices, renewable energy systems, industrial drives, consumer electronics etc. Simulation results showed the efficacy of this method.
