| Zusammenfassung: | A highly accurate rotation angle detection device is realized by correcting a detecting position error caused by a machining error such as deterioration of roundness of an internal diameter of a stator. The rotation angle detection device is provided with a stator (
12
), which is provided with an exciting winding of one phase and two-phase output windings, and a rotor (
13
) having salient poles, in which the stator (
12
) has a plurality of teeth (
11
), the two-phase output windings are wound around the plurality of teeth, and the plurality of teeth include teeth for which the number of turns of the output windings is N and at least one of teeth for which the number of turns of the output windings is N±m (it is assumed that N and m are positive integers and N>m) and teeth for which the number of turns is m. |
