发明名称 Resolver Abnormality Detection Circuit
摘要 An abnormality detection circuit for a resolver outputs a rotation angle signal corresponding to a rotation angle of a rotor from a resolver winding. In the abnormality detection circuit, the resolver abnormality detection circuit applies a specified signal to one terminal of the resolver winding, determines whether the specified signal is superimposed on the rotation angle signal outputted by an other terminal of the resolver winding, and detects abnormalities of the resolver based on results of the determination.
