Abstract

The development of synchronous reluctance machines and their wide scope of application entails the need to introduce new methods of these machines design in order to increase the power density in order to ensure the best indicators. The article shows the experience of using the finite element analysis in three-dimensional space in the design of a field regulated reluctance machine (FRRM). It is shown that with an increase in the number of phases, the pulsations of the electromagnetic torque decrease. The geometry and design of the machine's rotor allows an increase in torque without changing the dimensions of the FRRM. The dependences of the influence of the air gap on the torque amplitude and the torque ripple coefficient were also given. The proposed options for changing the geometry also complicate the design of the electric machine, however, the increased efficiency gives a greater economic effect during the operation of the machine.
