"Y"all Ever Seen a Motor Act This Stubborn

[bomberider]

Hello, I'm hoping to get some guidance from ya all, I have a150A 72v Sabvoton controller 72v 48ah battery pack with a 150A BMS and the motor is supposed to be a 12000w but unsure I do know that its referred to as the Golden Magic Pie according to cycle analyst V3.1 User Manual and the only real spec's are the 28poles unfortunately, i haven't been able to get any detailed specs for the motor, and it's been holding me back. Ill admit, I'm not the most experienced in this area, but I'm willing to learn. I'd like to know how to figure out the missing specs or optimize my set up with the Sabvoton controller. If you have any tips, similar experiences or maybe point me towards resources, I'd really appreciate it. Hey thanks in advance for your help!

That's 75mph. At a guess without doing any math, it would be around 20kw (20,000 watts) to do that. You *might* get half that out of the battery pack you have without setting it on fire.

Under what conditions did you see this speed, on what speedometer, and for how long?

If you saw this speed on your controller display or the cycle analyst, it is likely you have the speedometer set incorrectly.



There are no MagicPie motors for 12000w (12kw). 500w to maybe 1000w is the range of power they're specified for. Most of them have internal controllers that would probably catch fire if anywhere near that much power was attempted to be drawn from them.


Other than the number of poles for certain common motors (including the GMMP), to be used for the speedometer setup, the Cycle Analyst manual does not have information about specific motors in it, especialy not ones for your specific system, so you must be referring to some other manual that tells you what motor you actually have. I would recommend posting a picture of the page showing this information so we can help you understand what you are seeing, and give us a better idea of what you actually have there so we can properly assist you.




Probably not more than once, as it would be being driven nearly 20 times as hard as it was built for, and would probably overheat and burn up.

Did you have a chance to view the pictures that I had posted? Thank you for the suggestion, I could use your worldly opinion? it would mean a great deal to me,being the expert that you are, and I really could use your extensive knowledge. I have kind of hit a little road block.The throttle isn't getting any energy I've tested the connection and its checks out 4.7v. Maybe a fresh pair of eyes could spot something that I've over looked. Your help would be grateful appreciated

No throttle voltage, no power from the controller.
Start your search and measurements at the throttle.

A Big Thank-You to Everyone Who Helped!

I just wanted to express my sincere gratitude to Dominik H and everyone else who lent a helping hand while I was troubleshooting my bike. Thanks to your insights and patience, I was able to get things back up and running—everything is running as smoothly as it did when I first got the bike!

Your support truly made a difference, and I’m so thankful for the time and effort you took to help me figure things out.

To anyone else reading this, thanks for your input, even if it wasn’t always what I expected. It’s all part of the journey, I guess!

Best regards

So what did you find?

"Following dominik h's advice, I measured the throttle voltage for both minimum and maximum values. Once I had those readings, I entered the specs into the Cycle Analyst. I didn’t make any changes to the controller, which makes sense because the issues I was facing stem from the Cycle Analyst configuration. After these adjustments, everything worked perfectly! I tested the bike and hit about 110kph heading out of town with no problems at all."
