METHODOLOGY OF COURSE DESIGN OF ASYNCHRONOUS MOTORS WITH A SHORT-CIRCUITED ROTOR
The traditional method of calculating asynchronous motors is based on pie charts and substitution schemes containing errors exceeding 50%. If the numerical finite element method is applied, the error is reduced to 1%. The calculation methodology of an asynchronous motor with a short-circuited rotor can be made significantly more accurate even without using the methods of field theory explicitly. To do this, it suffices to take into account the results of cumbersome and long-term studies, which can be presented in the form of a series of tables. If manuals for the design of asynchronous squirrel-cage motors are supplemented with such an application, the accuracy of the calculations will increase significantly. Knowing the cross-sectional area of aluminum in the rotor based on the results of our previous studies will allow to repeatedly refine the result obtained without additional experimental studies.
