The interior permanent-magnet (IPM) machine is used in many industrial drives. In order to analyze performance and to design efficient and fast controllers, accurate knowledge of machine parameters such as d- and q-axes inductances is essential. Although there are a number of methods available to calculate these inductances, none of them is considered standard. Accuracy levels of all these methods...
The interior permanent magnet (IPM) machine is generally analysed with two axes theory. Machine parameters such as d- and q-axes inductances are needed for performance analysis as well as for controller design. So far no method appears to have been standardized to determine d- and q-axes inductances of the IPM machine. Normally, the classical methods available for the conventional salient pole synchronous...
