Abstract: The present invention relates to a method (100) for determining polarity of a rotor in an interior permanent magnet synchronous motor for use in a resolver offset calibration operation. The method (100) comprises: obtaining (S102) an estimated d axis current based on an alternating voltage signal injected into the motor; determining (S104), for each of a plurality of subsequent time periods, a maximum and minimum value of the estimated d axis current; determining (S106), for each time period, whether the corresponding maximum and minimum value fulfils a defined condition; integrating (S108) the maximum and minimum values of the plurality of time periods that fulfil the defined condition, thereby forming a sum of the maximum and minimum values fulfilling the defined condition; and determining (S110) the polarity of the rotor based on the sum.
