ebrom

Thanks d8veh, I will test the controller. I am sensorless so do not have hall sensors to test. I believe I did set the phase sequence correctly on the spare. That is, I am aware that the green, yellow, blue wire colors can be different sequences from one controller to the next. When I got the controllers, I set them both up to run correctly on the bike, the colors happen to be the same sequence.

Hi All, I have a 36V Goldant motor that just had a major breakdown. I am using it with ecrazyman controller with 6 fet 3077 210A fet. 24v thumb throttle. 12s lipo 44.4v-50.4v. Has run fine for me until recently. At the start of a ride, the motor ran for a few seconds, then stopped, only making slight clicking noises. It seems almost as if it is missing one phase of the three phases? I switched the controller and the same noise is made so I believe it is the motor. I have not tested with another throttle as I need to find my spares or order another one. How can I test/isolate the problem?

Hello All! Wanted to say hi and express my gratitude for this site. I've been reading for about a year and really enjoy all the insight about ebikes: technical, functional, and aesthetic. JerrySimon's Brompton/Goldant build struck a particular chord and has inspired me to do the same. I will try to go throttle only, super simple, and portable/removable in case I wanted to go back to non-ebike mode with the original front wheel. I intend to grind 9mm axles down instead of the forks. I will also use a removable throttle ala cleanrepublic.com hilltopper kit. As I am in Southern California and so far have not had any inquiry from police about my other ebikes, I am open to experiment beyond Jerry's "legal" setup and increase power/speed (ala I believe amigafan, cwah, ??). My first question would be how best to do so. I will try to document my build as best I can, but be forewarned my technical knowledge is limited, but I make up for it by being unfazed at trial and error! Wish me luck! lan
