The coupler design will be like this: The left side is the input shaft of the transmission and sticking through an empty transmission. The transmission is mounted solid and the engine is mounted to that. The universal joint is mounted to the end of the input shaft. The other end is bearing mounted and then somehow connected to the motor on the right. The motor on the right is an old Starter/Generator and there are actually two mounted on this Dyno for a load and checking torque. The end of the transmission case is cut to allow access to the end of the input shaft. The input shaft is connected into the clutch of the engine. No clutch is being used but that is the connection. Simple, easy and when checking the VW engine it can be pulled from the car and directly mounted without having to remove the clutch. Perfect. I should be able to duplicate this with little trouble. How to connect a universal joint to the motor is the issue.
As you can see (I think) this end of the motor has a taper shaft with key. An odd fit.
This end is a straight shaft with a key and as on both ends a screw to mount a tightening nut. Since it is an AC induction motor I can use either end and have it work. I am hoping to figure out how to build a coupler to utilize the end of a crank shaft for the VW and have an adaptor built so this can be mounted in a VW at some point for on the road testing in an actual car to see how viable the little motors will be for street use.
Anyway I am going to need help building this AC Induction motor inverter to run this little sucker.
