  • Patent number: 8928312
    Abstract: In a method for monitoring the determination of a rotor angle of a rotating shaft by use of a resolver monitoring the determination of the rotor angle is carried out by: a first test AC voltage at a test frequency which is not the same as an exciter frequency of the resolver is applied to a first stator winding of the resolver, and a second test AC voltage at the test frequency is applied to at least one second stator winding of the resolver, wherein the first and the second test AC voltages are produced such that an AC voltage is induced all the time in at least one rotor winding of the resolver as a result of the first and the second test AC voltages.
