I understand all the testing and experimenting that has been going on with the prototypes as being essential to get the motor rite, and find a controller that will work with this beast of a motor. I was just wondering if we are ever going to see this motor available to buy or have those plans been put on the back burner?

great work... is looking really good. You are getting up towards the torque levels we were getting. Should be heaps of fun on your little bike.

140 degrees C on the motor
Just under 80 degrees on the controller
120amps on the phase wires (all now withing 5 amps of each other)
So that means around 15nM continuous from this motor. Note that is with ZERO cooling! no airflow nothing. We should be able to double that with cooling.
