| Abstract: | A method to get the axis angle was introduced that the resolver is excited by the single-chip computer directly and the out- put induced E. M, F is measured by the single-chip computer. The digital resolver axis-angle sensor based on this method has the proper- ties of simple circuit and high reliability, Its measuring result was sent out by RS - 232 interface, and it was easy to use. The measuring precision of the resolver can be increased by adopting the interpolation method. |
