Theoretical aspects of optimization synchronous machine rotors

Permanent magnet synchronous electric machines are increasingly used in various drive technical complexes (oil industry, small generation, aviation industry, etc.). The presented optimization allows you to increase the energy performance of a synchronous machine without increasing the overall dimensions. Permanent magnet synchronous motors have become much more commonly operated in various drive technical complexes. For each drive complex, it is necessary to fulfil the requirements for the developed torque, cooling conditions and strength characteristics. The distribution of materials (topology) in the rotor casing of a synchronous machine (permanent magnets, iron, air, etc) determines the characteristics of permanent magnet synchronous electric machine.
