Abstract
To perform calculations of disk inductor generator at active capacitive duty and to correlate generator and load parameters for receiving maximum specific energetic indices it is essential to consider some important factors affecting generator characteristics. The calculation is carried out taking into account thermal limitations, actual inductance change curves received by solving field problems as the shape of inductance change curves influences generator characteristics. Heat calculations of inductor generator are of practical use when dealing with high voltage. Thermal limitations at continuous generator duty are considered to be important factors determining limiting indices concerning generator specific power. In doing so the main factor limiting generated power in the load is the temperature of generator winding insulation. Using simplified mathematical models on the basis of thermal equivalent circuit is a preferential calculation method of generator operating temperatures. It should be pointed out that thermal calculations are usually made along with aerodynamic and ventilation calculations of electrical machine cooling system to determine the shifting rate of the cooling flow. To increase the intensity of heat branching from the heated generator elements, a centrifugal ventilator with radial blades is fixed on the shaft. Heating temperature relation of the designed inductor generator elements before stable duty is settled is of exponential character and is determined by two main parameters-stable temperature and time constant of heating.
