Electric machine is one of key components in electric and hybrid vehicles. The knowledge on alternative solutions than PM machines is required by Swedish automobile industry. The project aims to develop a more sustainable motor solution for future large-scale electrification of vehicles. The solution is to vary the magnetic flux with the help of the rotor winding and brushless transformer to achieve the desired torque. The advantage is that the motor does not need expensive rare-earth permanent magnets that are environmentally destructive at extraction and difficult to be recycled. The solution has not only high performance in terms of energy efficiency, maximum torque, and safety, but also potential for low cost and good recyclability for mass production.
