An Extended dq Model for Fractional-Slot Concentrated-Wound Interior Permanent Magnet Machines Considering Non-ideal Machine Parameters

Part of the Springer Theses book series (Springer Theses)


In this chapter an extended dq model is proposed for FSCW IPM machines. This is obtained by transforming the detailed analytical formulae of the machine parameters from the abc-system to the dq reference frame. The detailed analytical formulae in the abc-system that were obtained in Chaps.  2 and  6 are used for this purpose. The proposed extended dq model contains new parameters; accordingly, experimental tests are discussed for their measurement. The average electromagnetic torque and torque ripple are then formulated based on the proposed extended dq model. The proposed extended dq model is evaluated through experimental results from a prototype FSCW IPM machine along with FEA simulation.
