Hello I have a question regarding changing motor controllers on a Daymak Amalfi, the bike was originally powered by a 84V lead battery. I dumped the lead battery in favor of upgrading to a lithium battery in the near future to save 100 lbs in mass, after hooking up the motor to the controller and a 60V/3A bench power supply for testing the motor will not spin. In my quest to get it operational I've done the following:
Upon opening the motor to change the hall sensors I noticed that the two of the leads from the hall sensor board had exposed insulation that was possibly shorted to the motor.
TL/DR: Connecting a lower voltage controller will usually make a motor work, though at a lower speed, right?
- replaced the hall sensors inside the motor which has a 10" x 3" tire
- tested the motor controller on a known functional motor that is rated 36/48V system
