Abstract


The article is devoted to the search and research of ways to optimize magnetic systems of contactless synchronous generators with a capacity of 30–50 kVA used in Autonomous power supply systems for ground-based mobile objects. The main atten-tion is paid to electric generators with a combined excitation system, the air gap magnetic flux of which is created by the combined action of permanent magnets of the main inductor and an electromagnetic adjustment link necessary to maintain the constancy of the output voltage when the rotor speed and generator load change. Ac-cording to the authors, with an increase in the power of the source over 30–35 kVA, DC machines will be replaced by generators of this type. The article also describes a machine with a fundamentally new magnetic system, which contains elements of the design of electric machines with radial and axial flux. The proposed magnetic system, according to the authors, allows us to fully utilize the potential inherent in machines of both forms, improve the specific characteristics and, most importantly, maintain the highest technical reliability inherent in contactless Electrical Machines.
