VERNIER RESOLVER

Fig. 2 — View of the assembled vernier resolver and its rotor. 



The stator lamination is of ten pole-shoes, each pole-face having 

 three teeth. All 30 teeth of the stator are equally spaced. The number 

 of equally spaced teeth of the rotor lamination is equal to the order "«" 

 of the resultant vernier resolver. 



The exciting winding, as in the simplified model, produces ac mag- 

 netic fields alternating in phase from one pole-shoe to the next. Each of 

 the two output windings is distributed over all ten pole-shoes. 



To describe the turns distribution of these windings it is necessary 

 to define the positive winding sense and the electrical angle of a pole-
