The Motor


​I decided that the best thing for me would be to connect the new electric motor to my drive train and to keep the transmission in place.  In this type conversion, there are two critical components needed, an "adapter" and a "coupler".  The adapter attaches the electric motor to the outer rim of the transmission while the coupler connects the motor drive shaft to the transmission drive shaft.  This option was instead of a direct connection to the drive shaft or an installation of an electric motor at the axel or wheel. (Discussed in "Convert It") 
The adapter and coupler were custom built by EV West.  I shipped the transmission and clutch assembly to EV West for their engineering.  ​
I felt the scope of the project was described by the schematic that is published with the engine in the EV West catalog.

Here at the outset, and with a busy travel schedule, I'm allotting a year for the project.

One year was to turn in to more.  And the schematic did not include the work to actually mount the electric motor in the car.  Nor did it describe the work need to install the Battery Management System "BMS".  Both matters are obvious requirements, and as the following pages indicate, challenging but interesting in a fun.

This the motor standing vertical from the floor.  The coupler is laid on the engine upside down.  It will be fitted onto the engine shaft with six threaded holes for the flywheel.  There is also a spacer ring that goes on the engine shaft first (not shown).



​









​The coupler has been mounted on engine shaft.  This was a new experience for me in that there is a little note included with the coupler.  "The coupler must be heated to 600 degrees to connect to the engine shaft."  This is know as an "interference fit".  The coupler will not slide on the shaft cold but must be expanded with heat, then slide onto the shaft and let cool to a grip appropriate for a drive train.  The stainless turned near black when heated in a kiln to 600 degrees.

​Here we see the adapter install on the motor.  This critical piece of engineering magic matches the engine as shown, and then maps perfectly to the transmission housing.  These two components, the coupler and the adapter, are deal-making components custom engineered by EV West using my transmission and clutch assembly as the model.

​The flywheel is connected to the coupler, and the clutch assembly to the flywheel.
Now we need to couple the motor to the transmission.
