Calculation of the conductivities of equivalent thermal equivalent circuit of electrical machines according to experimental data.
The method of calculating thermal conductivities of equivalent thermal circuits (ETS) according to thermal tests of electrical machines is set forth. Since the number of conductivities is usually greater than the number of ETS nodes, the problem can be solved if there are results of thermal tests of the machine under several load conditions. the number of thermal conditions. For many electric machines, it is sufficient to carry out two modes of steady-state heating (idle and nominal load, for example). Calculation of thermal wires These are made using a digital computer.
