Synchronous reluctance machines

The synchronous reluctance motor is a promising alternative for induction machines to achieve a higher efficiency, as required by the European Commission. The research focusses on the detailed electromagnetic design in order to achieve three targets: high efficiency, low torque ripple and high power density. Moreover, the control of the machine is investigated in order to obtain a stable behavior and a fast dynamic response. New developments at UGent are the combined star-delta winding in the stator and a permanent magnet assisted rotor, leading to 5% - 8% more output torque and 0.3% point more efficiency.
