Claim Text:
1. An angle detector comprising: a first signal level detector to detect a sensor processed signal having a maximum signal level of a first set of sensor processed signals obtained by signal processing of multiple sensor signals, each of the multiple sensor signals having a signal level corresponding to a rotational position of a rotor of a motor having multiple coils, a signal level adjuster to adjust each signal level of the first set of the sensor processed signals to match the sensor processed signal having a maximum signal level with a first adjustment level, a signal selector to single out a selection signal from a second set of sensor processed signals adjusted by the signal level adjuster, and a phase detector to output a phase information signal in which a signal level of selection signal selected by the signal selector corresponds to a phase of the rotor.
