Abstract

The present work’s goal is to develop the analysis of the behaviour of properties as: torque, total losses, magnetic density flux, in the three-phase induction motor with squirrel cage rotor when the material which compound the cage is changed. Aiming this goal, we used simulations of finite elements through the use of software FEMM, and for analysis’ purpose a performance comparison was made between copper and aluminum. Hence, it was noted that the aluminum configuration showed a torque of 454,338 N.m and total power losses equal to 105,71 kW, for cooper was obtained, respectively, the values of 345,219 N.m and 84,66 kW.
