| Title | Development of Direct Drive Motor Systems for Electric Vehicle to extend Field-weakening capabilities |
| Summary | Brief description: This project aims to address the reliability issues associated with gear-based systems by designing and implementing direct drive motor solutions. Gearboxes are prone to wear and tear, leading to increased maintenance costs and downtime. Direct drive motors offer a promising alternative by eliminating the need for gears, thereby enhancing reliability and efficiency. The project will involve designing, optimizing, and testing direct drive motor systems tailored for Electric Vehicle applications, with a focus on maximizing the constant power speed region. 1. Literature Review • Conduct a comprehensive review of existing literature on Electric vehicles motors and direct drive motor technologies. • Analyse the challenges and limitations of gearboxes in terms of reliability, maintenance, and efficiency. • Evaluate the potential benefits of direct drive motor systems, including increased reliability, reduced maintenance costs, and improved energy efficiency. 2. Motor Topology Selection: • Define the specifications and performance requirements for direct drive motor systems based on electric vehicle characteristics and operational conditions. • Evaluate and compare different motor topologies, such as induction motors, permanent magnet synchronous motors, switched reluctance motors, or others, based on their suitability for the identified applications. 3. Motor Design and Optimization: • Utilize simulation tools i.e JMAG to design and optimize direct drive motor configurations, considering factors such as torque, speed, power density, and size constraints. 4. Comparative Analysis: • Compare the performance and reliability of direct drive motor systems with traditional gear-based. • Quantify the advantages of direct drive motors in terms of reduced maintenance requirements, increased system reliability, and enhanced energy capture efficiency. • Perform a cost analysis to evaluate the economic feasibility and long-term viability of adopting direct drive motor technology. 5. Documentation and Presentation: • Prepare comprehensive report that outlines the entire design process, simulation results, experimental findings, and comparative analysis. • Create a clear and concise presentation summarizing the key aspects of the project, emphasizing the practical applications and potential impact on the industry. |
