I've used both an Ecitypower/BMSBattery universal controller in sensorless mode and a sensorless Ecrazyman Shenzhen controller on my Bafang so I don't see why the Shenzhen sensorless controller should not work with Cute motor. Make sure whatever throttle you're using matches the wiring on the controller and that the controller is indeed powering up. I know you said you used the controller on another motor but if you changed anything make sure it still runs that previous motor. If it does then hook up the Cute motor and it should run either forward or backwards. Do note however that if the wiring is wrong you won't see the wheel spin backwards because of the clutch but you will hear the motor spinning backwards in the case. You should then be able to get it to spin forward by swapping any two phase leads.SoSauty wrote:Me thinks the same, however the caveat is "sensorless". I did bring in the little red key wire and crimped it with the red power wire into the anderson connector. The Shenzen seems straightforward enough, what else can I try besides hooking it up and putting a multimeter in series to see if power is exiting the controller? The cute motor looks suspious at this point.That sounds like some ass-covering.
Should I try other wiring combinations: Green to green and other pairs; Yellow to yellow and other pairing. What can I check with the motor and multimeter, any continuity to be expected with the 3 motor wires?
