Abstract | [Abstract] A significant part of this thesis project has been devoted to development of systematic design procedures for printed circuit stators. In particular those procedures include algorithms which allow performance comparisons of several stator coil shapes. A new coil shape, with improved Computer efficient numerical models have been developed to predict phase inductances and stator eddy-current loss. Sufficiently accurate phase inductance predictions make possible theoretical assessment of performance of motors under sensorless commutation control that is based on the equal inductance method. The proposed method of calculation of eddy current loss allows designers to determine the track width beyond which eddy current loss becomes excessive. The mathematical model on which the enhanced equal inductance method is based and those that have been used for performance assessment, inductance prediction and eddy-current loss evaluation have all been validated by specially designed laboratory tests carried out on prototype motors. |
