Abstract: Alternator is a motor used in aero applications where speed matters. It consists of two parts named as stator and rotor. Stator is prepared by silica steel laminations to increase the motor efficiency. Holding of individual glued laminations is mandatory to prepare a stator. This project is deals with the design of a special purpose tool, can be called as jig, which can hold all the laminations and stack them in a skewed manner in order to reduce torque ripple in alternator. Jig was designed by considering single lamination dimensions and stack height. Modeling was done using CATIA software and fabrication by using CNC machine.
