We are excited to announce the launch of a new innovative research project titled “Development of Multi-Phase Permanent Magnet Starter/Generator (PMS/G) with Bi-directional DC-AC Converter for More Electric Aircraft (MEA).” Led by Dr. K.R.M. Vijaya Chandrakala, Associate Professor at the School of Engineering – Department of Electrical and Electronics Engineering (EEE), Amrita Vishwa Vidyapeetham, this project aims to advance the development of electric propulsion systems for the aerospace industry. This research was supported by co-investigators Dr. S. Saravanan, Assistant Professor, Department of EEE, Amrita University and Dr. S. Balamurugan, Professor & Chairperson – EEE, Amrita University.
Project Overview:
This project focuses on the design and development of a novel compact Permanent Magnet (PM) machine tailored for electric aircraft applications. The main aim is to enhance the fault-tolerant capability of the machine while improving its torque and power density, and reducing the power-to-weight ratio for better aircraft performance.
The research team will integrate the PM machine with a bi-directional DC-AC converter and employ Field Oriented Control (FOC) using a flux weakening approach. This will be driven by a Voltage Source Converter (VSC), ensuring enhanced energy conservation and fault tolerance during operation.
Key Objectives of the Project:
Envisioned Outcomes:
This project will deliver a multi-phase Permanent Magnet Starter/Generator (PMS/G) that will significantly contribute to the development of electric propulsion systems. By optimizing the design for aerospace applications, the system will provide an efficient and fault-tolerant solution for more electric aircraft (MEA). The integration of the bi-directional DC-AC converter and the innovative control technique will pave the way for future advancements in the indigenous development of electric machines in the aerospace sector.
Emerging Areas and Impact:
The project will contribute to key emerging areas in electric propulsion systems and compact drive mechanisms, directly supporting the growing demand for green energy solutions in the aerospace industry. By leveraging indigenous special electric machines, the work aligns with national goals to develop sustainable and efficient technologies in the aviation sector.
The development of this PM starter/generator with advanced control techniques will have a direct impact on the energy efficiency and fault tolerance of electric propulsion systems, thereby advancing the More Electric Aircraft (MEA) paradigm.
