Abstract:
A failure determination device for an angle detector for a rotating machine, including: an angle detector, which includes n pole pairs (n>m), and outputs sine and cosine wave-signals in accordance with a rotational position of a rotating machine including a multi-phase winding and m pole pairs (m≥2); and a failure determiner for detecting failure of the detector based on signals from the detector. The detector outputs first and second sine-wave-signals having 180° phases different, and first and second cosine-wave-signals having 180° phases different. The failure determiner determines malfunction of the detector when the failure is determined with use of at least one of: failure determination using a sum of the first and second sine-wave-signals and a sum of the first and second cosine-wave-signals; or failure determination using a sum of squares or a square root of a sum of squares of the sine-wave-signal and the cosine-wave-signal.

Claim (Index 26):
An angle detection device for a rotating machine, the angle detection device comprising:\n the failure determination device for an angle detector for a rotating machine of  claim 10 ; and an angle calculator to calculate a rotation angle of the rotating machine based on signals from the angle detector, wherein the angle detector includes a plurality of angle detectors, and wherein, when the failure determiner determines that one of the plurality of angle detectors used for calculation of the rotation angle is out of order, the angle calculator calculates the rotation angle with use of signals from another one of the plurality of angle detectors that is not out of order.
