Mechanical drive train complete

Written by admin. Posted in AC Traction Motor

This stainless steel box structure has to be able to withstand the significant torque the motor puts out (or takes in with regen) to/from the drive shaft. This low profile design allows for best clearance with the battery pack and water cooling lines.


The 0.25 Inch thick plate all welded into a rigid, 20 pound structure. Yep, some of that weight could be removed.. maybe later.

Here is the mounted end result firmly “floating” in place

The only remaining detail in the mechanical drive train is the installation of the lightweight ALU flywheel to reduce the side loading on the electric motor shaft for long life. It is functional for now.

BTW, speaking of long life, this motor will not change it’s power delivery over time as there is simply no wear mechanism other than the bearings, which can be replaced every decade or so.
