  • ROTOR WITH A COMPENSATING MASS FOR A RELUCTANCE RESOLVER, AND RELUCTANCE RESOLVER
    Publication number: 20110285387
    Abstract: The invention relates to a rotor (1) with a signal transmitter mass (3), which is distributed non-uniformly in the circumferential direction (U), for a reluctance resolver (16) and also to a reluctance resolver (16) for converting a rotational value into an electrical signal based on a change of a magnetic field. In order to minimise an unbalance, generated as a result of the non-uniformly distributed signal transmitter mass (3) during operation, and wear phenomena resulting therefrom, the invention provides for the rotor (1) to have at least one non-magnetic compensating mass (4) compensating for the distribution of the total mass (2) of the rotor (1).
