Therefore, the actual problem is the development of a mathematical model that allows one to calculate the mechanical characteristics taking into account the change in parameters due to the saturation of the magnetic core and the displacement of the current in the rods of the squirrel-cage winding as having a determining influence on the characteristics of the IM.
The object of the study is a IM with a squirrel-cage winding of a rotor, which is powered by a three-phase network with a symmetric voltage system.
1, 2) shows that the general view of the characteristics of the electromagnetic torque for IM with a different shape of the slots of the squirrel-cage winding of the rotor is significantly different, and the voltage reduction is proportional to the decrease in frequency does not ensure the immutability of the reloading capacity of the IM.
