New Electric Drive for Car Shredder

This paper analyses performance aspects of a brushless double fed cage induction motor as a new driving alternative to the classical wound rotor induction motor used in a car shredder drive. It focuses in a real application of 3150 kW - 4160 V - 60 Hz - 514 rpm wound rotor induction motor. Firstly it analyses the car shredder duty and compares the performance of the two motors without a controller. The starting condition is analyzed and a Matlab/Simulink simulation is used to show the advantages of the brushless double fed cage induction motor over the classical wound rotor induction motor, in rated operation condition. The performance of the two drives is compared using the simulation results
