Synthesis of the rotor circuit of an induction motor according to the specified characteristics of dynamic braking.
The problem of synthesizing the external circuit of the rotor of an induction motor according to its frequency response has been solved in order to obtain in advance a given mechanical characteristic of dynamic braking. A method of approximation of the frequency characteristic of the conductivity of an external rotor circuit expressed in graphical form is proposed. As a result of the synthesis, a linear passive circuit of the rotor with lumped R-L parameters was obtained. An example of the synthesis of a rotor chain is given, which provides dynamic braking characteristics with a constant braking torque.
