1. Analysis and Reduction of Parasitic Effects in Induction Motors With Die-Cast Rotors
Sammanfattning : This thesis presents a study of inter-bar current effects on induction motors with die-cast aluminium and die-cast copper rotors. The parasitic effects introduced by these currents are analyzed and possible solutions to these problems are presented. This is realized by developing analytical tools for the simulation of inter-bar current effects. LÄS MER
2. On Inter-bar Currents in Induction Motors with Cast Aluminium and Cast Copper Rotors
Sammanfattning : This thesis presents a study of the effects of inter-bar currents on inductionmotor starting performance and stray-load losses. The work is focused on theperformance differences between aluminium and copper casted rotors.A method to predict the stator current when starting direct-on-line isdeveloped. LÄS MER
