MS student Yangxue (Sherry) Yu with advisor K. Haran It is important to understand rotor dynamics and correctly capture the rotor’s critical frequencies to predict and improve a motor’s performance. For an external rotor design, the presence of the trunnion effect, modeled as a rotational stiffness at the hub of the trunnion plate, may shift […]
Brushless Doubly-Fed Reluctance Machines for Turboelectric Distributed Propulsion Systems
MS student Shivang with Advisor A. Banerjee Turboelectric propulsion uses no batteries for propulsive energy during any phase of flight (unlike hybrid and all-electric systems) and is considered a critical enabler for low-carbon emissions in the aircraft industry. As batteries with high enough power capacity and the specific power required for commercial aircraft are unlikely […]
Insulation Design and Qualification for Form-Wound Air-Core Armature Windings in High-Frequency Machines
PhD student Thanatheepan Balachandran, Post-doc Yalin Wang, and MS student Yovahn Hoole with advisor K. Haran A NASA-funded inside-out permanent magnet synchronous motor (PMSM) is developed to demonstrate electric propulsion for commercial electric aircraft. Air-core machine windings are manufactured at UIUC. Insulation qualifications of these windings are evaluated for ground, high-altitude, and life-time tests. The […]
