<P>PROBLEM TO BE SOLVED: To enable the extraction of a rotation angle output signal with no crosstalk to the outside by radio through an R/D converter and a rotation angle output signal radio output part provided in a rotor without using a rotary transformer. <P>SOLUTION: A resolver provided with radio output function according to this invention has a signal processing part (40) provided in a rotor (8) and having an R/D converter (12) and a rotation angle output signal radio output part (41). Since a rotation angle output signal (10) obtained from a rotor coil (7) is transmitted to the outside through the rotation angle output signal radio output part (41) after being subjected to R/D conversion by the R/D converter (12), crosstalk between an excitation signal (12a) in a fixing side of the revolver and the rotation angle output signal (10) is prevented to be able to output the rotation angle output signal (10). <P>COPYRIGHT: (C)2013,JPO&INPIT |
