Okay I got my 409 motor finally and being new to the hub motor arena need some help. First off I wanted to put the motor on a wheel stand and test it out along with my new motor controller before spending close to 100 bucks to get it built into a rim. Already I am confused…included is some hardware attached to the axel. On side one with no wires (pictured below) there are two drop out locks (one of which only fits on the back groove which is larger), a lock washer, and lastly a nut. FIRST QUESTION: why are there two drop out locks and are they in the correct order.
Rim side two (with wires)(pictured below) only has a washer then a nut. QUESTION TWO: When I mount this on the stand or a bike am I supposed to put an additional nut on the motor or just loosen the nut that already there. I’m guessing additional nut because it looks as if that current nut is protecting the plastic with the wires.
QUESTION THREE: Do I need a home built torque arm? I plan to run this motor at 66v at 20 amps so that equals at peak power 1320 watts, almost 2 hp IN!
Let me know if there are any other suggestions for setting up this motor. In theory this system should be awesome!
PS sorry for the oversized pics just wanted to make sure you could see
