Hi, I have 2 motors at the moment and now both of them are not working. the 2 motors are a MW Motors 36v 250w motor (made by bafang and just rebranded) and a MAC 6T. I got the MAC 6T in trade from someone here on the forum so I don't know its history. However, both motors ran great on a 36 volt 250w controller that I had them hooked up to. the MW Motors motor has about 4000 miles on it with this controller and the controller was just used to test the mac 6t. I also have a 72v 500w controller that both motors ran fine on but the little one kept getting hot and it fried for some reason. it was cheap so I just threw it away and ran the 36v controller again for a while.
I just received a new 72 volt 350w controller for the small motor (which is a torque wind so it only goes 15mph on 36v in a 24 inch wheel). I hooked it all up and it had a self learning wire that you plug in and it is supposed to sort itself out. I did not realize that this self learning function bypasses the throttle so when I connected the wires the bike flew across the basement and the rear wheel bounced a few times when it hit the far wall and then even though the motor was spinning like a madman, the wheel was not turning. I believe I fried the clutch.
This morning, I decided to hook up the mac to what it would do on 72v 350w and I made sure that the rear wheel was off the ground this time. I hooked everything up and plugged in the self learning wire and the internal of the motor spin but the wheel never turned. Not even one revolution.
Obviously that controller is going in the trash bin.
Did I really just fry 2 clutches?
I hooked up the old 36v 250w controller and the internals of moth motors spin but not the wheel.
I am at my wits end here. How can a MAC clutch go like that (if it is the clutch) on only 350 watts unloaded.
If it will help I can take photos of the MW Motors motor but I haven't taken the MAC apart yet.
Any input would be much appreciated since now I am human power only.
