Synchronization of Reluctance Motors

In most of control and industrial applications, a high degree of rotational stability and uniformity of speed is required. These requirements can be achieved by using reluctance motors. The synchronization process of such motors is of prime importance for these applications. Therefore, a simple and accurate criterion is developed to define this process. The validity of the criterion developed is confirmed through experimental results. The effect of supply voltage variations, the supply frequency and the ratio xd/xq on the synchronization process is investigated.
