Abstract
The article considers the influence of losses in steel of Field Regulated Reluctance Machine (FRRM) on its specific values and the electric drive control system. Two methods of their determination are analyzed: analytical and field. The second method is preferable, since it requires less information about the properties of materials with the same accuracy in determining losses. It is shown that losses in steel shift the optimal control angle of the stator current vector towards the q-axis of the electric machine. The angle offset when the load is increased to three times is 5 electrical degrees. It is shown that when the load current increases, the losses in steel to eddy currents and hysteresis are equally dependent on induction. With three times the load, losses increase by 60%. As the speed increases, the eddy current losses from the current increase squared, and the hysteresis losses are almost linear. This indicates a different degree of dependence of the loss components on the speed. Regression dependences of losses on the load current and speed of FRRM are given.
