Features of synthesis of synchronous reluctance and inductor electric machines

The problem of finding the best dimensions for the elements of magnetic systems of synchronous reluctance and inductor electric machines in an extended range of changes in load torque and power is considered. An algorithm for solving the problem is also proposed, involving the division of the elements of the magnetic system into two groups. The first group affects the magnitude of the torque pulsations, while the second does not affect this indicator. Such partitioning accelerates the process of convergence of the result. A method of sequential non-linear programming is proposed for resolving the problem. It has good convergence with minimal search time. Synthesis of finite element models of a synchronous reluctance machine with salient pole and anisotropic types of rotors, switched reluctance machine (SRD), machine with field switching (FSDC), Vernier reluctance and double field Vernier reluctance machines was performed. It was shown that the proportion of winding copper relative to steel in the active part of the machines increases relative to conventional machines when operating in the nominal mode. On the contrary, this feature was manifested to a lesser extent when working in the zone of overloads in terms of torque. Electromagnetic loads increase with increasing power, equivalent to operating a machine of lower power in overload mode. It was shown that the sensitivity to the size of the air gap in Vernier reluctance machines is the highest in the class under study. Thus, with increasing
