Abstract: A variable reluctance synchro was proposed which has the same performance as variable reluctance resolver. The principle and the design rules of variable reluctance synchro were presented, the selection principle of the tooth-slot number and winding distribution was mainly analyzed. The main factors affecting the electrical error and the relationship between the electrical error and the rotor shape were briefly analyzed. The prototype of the variable reluctance synchro with the pole number of 5 was developed. The electrical error and other basic parameters were tested. Compared with the variable reluctance resolver with the same size and the same pole number, the variable reluctance synchro has similar performance but has more advantages in design and technology.

Key words: variable reluctance synchro, styles of winding, number of teeth and slots, electrical error
