Sometimes I need to ask more questions. I ordered and received my new 36V my1018 motor to replace my burnt Currie issued 24V version. It came from TNC Scooters, who listed it cheapest I could find on the USA internet (50 USD for the 24V, 55 USD for the 36V, shipping and handling about 18 USD, a little pricey for 6 pounds). I figured it would be too expensive coming from Currie, if they had a 36V version available.
I was a little surprised to see that the four screw holes which are used to hold on the large drive gear cover would all need to be modified to match the Currie setup. Of course, after I gathered all the tools to make the mods, I realized I could just swap out the old motor cover on the side of the drive gear instead, to have the previously existing Currie setup on the new motor.
Since I had the drills and taps out already, I proceeded to modify the new motor anyway. Two of the holes had to be drilled out larger and deeper, then tapped for 10-32 threads. Two others had to be drilled large enough and all the way through, to slide the two countersunk 10-32 screws through. This was easy enough to do with a hand drill and manual tapping into the soft aluminum casting.
Good thing I used wire nuts to connect the new motor to the old motor wires. the old motor wires have additional length needed and the right connector at the speed controller end. I was going to solder some nice connectors together instead, but changed my mind. I put the red wire to red wire and black wire to black wire. The motor ran the opposite direction I needed!
Next week I'll continue with my Ping lifepo4 36V 20AH battery distance test to and from work. My next ride to work may put me at 28 miles, pretty close to my 30 mile goal. I'll be going a lot slower again (around stock speed) on this fourth 7 mile leg with this new motor/battery combo.
