Optimum Design of Slot Shape for Preventing the Misrun of an Aluminum Motor Rotor in Die Casting

摘要

The optimum design for slot shape of aluminum motor rotor with diameter of 450mm was performed to prevent the misrun in die casting process. In order to do it, the effects of the variables including slot width and slot length on the misrun of the aluminum motor rotor with various core length in die casting process were evaluated using numerical analysis. The critical solidification modulus and slot width for preventing the misrun of the aluminum motor rotor increase with an increase in core length. Based on the results, the design criteria of slot shape for preventing the misrun of aluminum motor rotor with various core length were established.
