Synchronisation of high performance reluctance motors by increasing the supply frequency

This paper presents a new technique for starting a high performance reluctance motors which cannot pull into step at normal operating condition. The proposed technique based on starting of the reluctance motor al frequency higher than the normal frequency. At the instant that the rotor speed reaches the synchronous speed of normal frequency. The main aim of the paper is starting and pulling into step of reluctance motor while keeping the desired performance without changing the motor parameter and design.
