Abstract :
Serious thought is being given to the use of die cast copper cages; this is why the cost of copper for cage manufacture might become reasonable, even for small motors. Eight optimum designs are presented; two different powers, two different objective functions (initial price or total price including the price of future losses), and two cage materials (copper and aluminium) have been considered. Various components of prices are compared
