The flywheel weight reduction project

Written by admin. Posted in AC Traction Motor

This chunk of ALU will be machined to match the critical surfaces and mounting locations of the original steel flywheel. The back side will be significantly hollowed out leaving only the material needed for structural strength.

After some time with the bandsaw, here is the flywheel taking form:


The small steel adaptor (bottom center) will allow me to mount the big ALU chunk in the lathe for final balancing.

Most of the material will be removed with the milling machine via the rotary table.

An alignment pin will center the ALU plate on the rotary table
