Dissertation note: Thesis (Ph.D.) - Cairo University - Faculty of Engineering - Department of Mechanical Design and Production Summary: In this research work a centrifugal casting machine driven by a separately excited DC motor and proposed AC motor is investigated. The study has been carried out using two methods of simulation; mathematical modeling and laboratory experiments. The mathematical model has been validated by comparing the simulation results with actual measurements taken with the DC drive. On the other hand, In order to regain the mould expected service life, for improving the operation economic and technical sides, a study of the factors that reduce this life was carried out. The strain measurements were used as indirect indicator for adjusting the mould alignment. The study conclusions were used to develop recommendations and prepare action plans that would improve the mould service life
