Calculation of the Braking Force Transitional Processes for Linear Induction Motor
Issues on the modes of the electric braking of the linear induction motors (LIM), the patterns for the calculation of the braking force are discussed. There is stated the fact that for the analysis of all modes of braking there is applied the spectrum method, based on the theory of electromagnetic field and Fourier integral transformations. There is determined that the transitional processes of the braking force of LIM Felm f (t) are characterized by means of three components of the force evaluating the change of the velocity of the secondary element, the transversal edge effect and interrelated interaction of the transversal and longitudinal edge effects. Following the expressions derived, separate components of the force are calculated by means of software Matchad 2001 Professional. The results of the calculation indicate that in the model of the motor with the infinitely long active zone at the initial moment, the braking force is not generated that is why such a model from the point of efficiency of the braking process is insufficiently correct.
