"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!

As you have provided no data from the motor, start with 80A battery current and 250A phase current, ride it and check motor temperatur, if it stays cold, raise battery current and phase current.
Be carefull, uphill you need much more power than on flat ground, motors normaly overheat uphill.

 

[bomberider]

Thanks for your advice! To provide some context, the situation started when i was trying to set up the Cycle Analyst. Without clear instructions, I had to rely on guesswork, and unfortunately, this led to the accidental reset of the controller. Now the bike is unrideable to test or monitor the motor's temperature while riding. Given these challenges, I'm looking for alterative methods to safely test or configure the motor while it's stationary. Any idea's or guidance that could possibly help would be great. Thank you

The cycle analyst doesn’t communicate with the controller, so it would be odd that messing with it would reset the controller. Can you describe the steps you took that led to the reset?
If your motor is the Golden Motor Magic Pie, then perhaps you meant 1200W instead of 12000W. The motor is rated at 1000W continuous, although it can take a lot more for a short time. You can probably run 40A if you keep an eye on the heat.

 

[dominik h]

If it is only a 1000W Motor, then start with 40A battery and 120A phase current.
Messing with the cycle Analyst does not change any setting in the controller, probably you have set the cycle Analyst totally wrong, so that the sabvoton does not get a decent throttle voltage.

 

[bomberider]

To clarify, I was the one who reset the Sabvoton controller. It was an accident—I thought it would behave like the Cycle Analyst and return to its original settings. Instead, it wiped all the configurations and reset to factory defaults, leaving the bike unrideable. I apologize for not fully explaining this earlier and appreciate your patience.

I also want to emphasize that I’ve spent the past five years trying to obtain detailed specifications for the motor from the seller without success. This lack of critical information has made optimizing the setup and troubleshooting much more challenging. Given these circumstances, I’m looking for advice on safely testing or configuring the motor while stationary—or any tips on how to proceed without complete motor specifications.

Thank you for taking the time to read and consider my situation. I genuinely appreciate any insights or advice you’re able to share.

Please confirm that your motor looks similar to the one below. Can you clarify whether: this is a new install, so you haven't gotten anything to run yet, or, it used to work with the controller, and you messed around and lost all the settings that used to work. Or something else.

 

[dominik h]

Sabvoton is realy easy.

You have to set
under voltage cut off
battery current
Phase current


Do a phase shift angle learning

Turn off weakening field when you do stationary tests, because you can kill the controller while running the motor without load.

Post Screenshots of the settings in the sabvoton App, because I shure have missed something.
I left the sabvoton Route two years ago, but I once did a Reset at the roadside , it took less than three minutes until I could drive back home.

just to clarify can a 1200w motor go over 100kph?

just to make sure can a1200w motor go over 100kph. because if it can't the motor i have does, when I first rode it , it went to 120kph

 

[amberwolf]

when I first rode it , it went to 120kph

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.

just to make sure can a1200w motor go over 100kph.

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.

Hope you get it figured out!

_"If you're talking about the motor, I've had it for five years, and it's never burned up or had overheating issues. However, if you're referring to the Cycle Analyst, it burned out shortly after I bought it. One more detail you might not know—the Cycle Analyst I was using at the time (and no longer use due to the issues) actually came from another bike I own. If this doesn't clarify things, I'm happy to explain further until it's completely clear!

 

[bomberider]

I will be posting screenshots of Sabvoton controller MQCON app images asap

Controller settings do look ok for me, if the motor is a 3000-5000W Motor.
I have driven my 180kg heavy scooter 12000km with a QS260 60V5000W motor and a 21S 100Ah Li-NMC battery, with nearly the same settings. Overheating the motor was only possible during longer uphill rides.

Except the current limiting voltage, that should be higher than the undervoltage setting

 

[bomberider]

All the settings that you see other than a live feed (if there is one) are factory settings when I pressed the reset it changed the settings to factory settings when i pressed the reset I assumed the controller would reset back to the original settings of the motor and other functions like what the CA does but it didn't the green indicator light on the controller is still functioning it has power but no throttle I'm not sure but QS V3 273 40H could be the motor's make and size but not positive. the attached file is all that i received as I assume

i was wondering if you still think my motor is a1200w and not the 12000w after i posted the pictures, the supplier that i bought the bike from was giving me false information about the 12000w. could it be maybe 8000w and peak is 12000w, in any case i would appreciate your opinion

 

[dominik h]

A QS273 40H can handle 12kW peak on a bicycle.

Factory settings are ok for your motor.

Did you do the hall sensor test in the app?
That is the only thing that is really nececary.

Does your App Show throttle values (0,9-4,5V) when you turn the throttle?
The 0,01V shown on your Screenshot is way to low for a hall throttle.
If it does not show throttle values you have no throttle Signal, and that is your problem.

If you see values, then you have probably a potentiometer throttle, then try to set the throttle min value to 0.3V.

 

[E-HP]

I'm not sure but QS V3 273 40H could be the motor's make and size but not positive. the attached file is all that i received as I assume

The pic looks like a qs273, not a Crystalyte hub. That motor is rated at 12kW.

[bomberider]

Hey everyone, first off, thanks again for your patience and advice. I wanted to share a bit about where I'm coming from—I can take this bike apart and put it back together again without breaking a sweat, but when it comes to the technical setup and troubleshooting, I’ll admit I’m a bit out of my depth. I’ve been up all night trying to figure out how to navigate the site and post screenshots, so if I’ve missed anything important, I truly apologize. I really appreciate all the help and insights so far—they’re helping me learn and get closer to figuring this out."

 

[E-HP]

Not performance related, but on your settings

I believe current limiting is usually higher than the lvc, to allow the controller to throttle back power when the battery is low, so you can limp home before the lvc shuts it down. The lvc value looks correct, so if you want the controller to throttle back before it shuts down, the current limiting value should be set higher.

40v, or 2v per cell, seems to low to me for a 20S battery.

The 0.01V shown on your screenshot is way too low for a hall throttle. If it does not show throttle values, you have no throttle signal, and that is your problem. If you see values, then you probably have a potentiometer throttle; in that case, try setting the throttle minimum value to 0.3V.


There is a hall sensor test in the app. To be honest, I have no idea how to test the hall sensor. I've been a bit reluctant to try anything until I have a better understanding of the problem. From what I’ve seen, the throttle minimum value might need adjusting to 0.3V—could this be contributing to the issue?

 

[dominik h]

For the hall sensor test, the rear wheel has to be lifted from the ground, and then activate the hall sensor test, and the controller will do everything for you. If the motor does not turn you have to raise the current.

When you twist the throttle to full, do you see >4V in the app?

 

[bomberider]

I did get the hall test done, the Throttle min voltage value 1.11 Throttle max voltage value 4.45.
Throttle twist unfortunately the value didn't move off 0.00 to 0.01. I had noticed that it wasn't moving off 0.00 so I didn't fully twist throttle to max. I do have another throttle that I can switch out if you believe that it could be the problem.

 

[dominik h]

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