Project description
Brushless, rare-earth-free electric machines
Europe’s dependence on rare-earth materials presents a challenge for the sustainability of electric machine (EM) production. Additionally, conventional wound-field EMs rely on brushes for rotor excitation, leading to maintenance issues and reduced reliability. The demand for more cost-efficient, durable, and environmentally friendly EM solutions is growing. Eliminating reliance on rare-earth materials while ensuring high performance remains a key objective for future electrical machine design. Supported by the Marie Skłodowska-Curie Actions programme, the HARMFIX project is developing a novel rotor field excitation method to achieve brushless operation in wound-field EMs. By introducing a new armature winding configuration and optimising the machine’s topology, the project aims to reduce copper consumption and eliminate the need for costly auxiliary components.
Objective
This project is focused on the design and development of new rotor field excitation methods to achieve brushless operation for wound-field electrical machines (EMs). The proposed method will provide an opportunity to reduce the reliance of EMs on rare-earth materials of which EU is lacking its resources and eliminate the usage of brushes for their rotor field excitation while improving the reliability and cost-efficiency of the machine systems. Through this method, a new armature winding configuration will be developed to generate not only the fundamental magnetomotive force (MMF) but also a suitable harmonic MMF component in the airgap of the EMs, while powered from a single customary current-controlled voltage source inverter (VSI). The rotor of these machines will be altered to house both harmonic and field windings. The harmonic MMF component will be employed to induce a harmonic current in the harmonic winding of the rotor, which will be rectified to excite the rotor field winding to achieve brushless operation and develop torque. A new topology optimization methodology will be developed to optimize the windings and minimize copper consumption. The EMs employing HARMFIX do not require rare-earth materials, costly auxiliary electromechanical excitation systems or custom-made power electronics circuitry, or control strategies for their brushless operation. Therefore, this method is a truly viable and sustainable alternative for commercial products which are currently employing rare-earth materials, brushless exciters or brushes, and slip rings.
