The study to substitute aluminum for copper as a winding material in induction machine

Abstract

it is to make motors more efficient because of the higher conductivity of copper. In addition, reduced losses in such motors may lead to better design flexibility and motors are more compact. However, copper price and weight is higher than aluminum so, copper wire motor has disadvantage compared with aluminum wire in manufacturing cost. This paper presents aluminum wire motor design to reduce motor manufacture cost and compares the cost with copper wire motor.
