1. An apparatus for estimating a motor parameter, comprising:
an input interface to receive an operating parameter of an electric motor,
a first device to perform a first parameter estimation algorithm estimating an estimated first motor parameter based on the operating parameter and on an initially determined second motor parameter,
a second device to perform a second parameter estimation algorithm estimating an estimated second motor parameter based on the operating parameter and on an initially determined first motor parameter,
a third device to perform a third parameter estimation algorithm estimating a revised estimated second motor parameter based on the estimated first motor parameter and on the operating parameter, and
a fourth device to perform a fourth parameter estimation algorithm estimating a revised estimated first motor parameter based on the estimated second motor parameter and on the operating parameter.
