An output section of one detection coil 112 of a first resolver 110 and an output section of one detection coil 122 of a second resolver 120 are connected by a first inter-coil resistor element 150, and an output section of the other detection coil 113 of the first resolver 110 and an output section of the other detection coil 123 of the second resolver 120 are connected by a second inter-coil resistor element 160. A sin wave signal for excitation is supplied to one of first and second excitation coils, and a cos wave signal for excitation having the same frequency as that of the sin wave signal for excitation and having a phase delay of 90° in relation to the sin wave signal for excitation is supplied to the other of the first and second excitation coils. By virtue of this configuration, the rotational angles of the two resolvers can be calculated even when one of detection lines is broken.
