Hi All,
How is it possible to convert the 60deg to the 120deg motor and vice versa?
Thank you
-
Why would you do that?
For improvements?
I am noob at this issue.
-
Why would you do that?
1) to improve my knowledge (most important)
2) I have 60deg motor and 120deg controller - I'd like to make them work together
How is it possible to distinguish between the 60deg and 120deg motors?
Thank you!

You can buy the e bike tester or you can just ask the manufacture ;D
You want to change the hall sensors degrees?
Well for 60 deg all sensors marking (label) are facing the magnets.
Well for 120 deg only the middle sensor marking (label) is facing away from the magnets.
To modify your controller to different is more difficult....I don't which in the controller is controlling the motor degrees.
But most controller support both, you can change in the programmable software.

The eBike Tester says it's the 120deg motor. The hall signals also match the 120deg sequence.
But... I opened the motor and realized that all the sensors are facing the same direction (labels toward the magnets) - as in the 60deg motor. The Hall Sensors are placed in 60deg one from another while the phase windings starts in 120deg one from another... So, I'm slightly confused what the motor is...
I'm attaching the motor's picture - please take a look.
Thank you
-
Yes most motors are 60 deg.
Well if the motor is 60 deg. while don't try to connector your 60 deg. motor?
You can see if it's the configuration.
-
Again, But... all the sensors inside of the motor are facing the same direction (labels toward the magnets as in the 60deg motor), but the eBike Tester detects the motor as 120deg one. The Hall Sensors are also placed in 60deg one from another while the phase windings starts in 120deg one from another... So, I'm slightly confused what the motor is...
-
Aaha now I understand you.
Hmmm that's kinda strange, maybe you should ask the manufacture?
Or which model is it?
-
... maybe you should ask the manufacture?
... which model is it?
This is 48V Trikke's motor (www.trikke.com). The manufacturer doesn't agree to disclose any information neither regarding the motor nor the controller...
-
Did test the controller and motor sequence?
If those are the same it should be fine.
And I am confused how you can determine the phase wiring degrees?
Hall sensors have only degrees and motor wiring just the phase sequence.
-
Did test the controller and motor sequence?
Yes, I found 3 combinations (out of 36), which have the same performance and power consumption (~2Amps with no load) and move the vehicle forward. Here I'm also slightly confused since I know that only a single combination should be found for each direction (not three combinations).
And I am confused how you can determine the phase wiring degrees?
Hall sensors have only degrees and motor wiring just the phase sequence.
You are right, only sensors has a degree config and sequence, the windings only their sequence... BTW, is there a matter what's the placement of the sensors inside the motor (degree/distance between the sensors) or only the sensors' polarity is the matter?
-
Just sensors degrees matters and ofcourse the sequence.
Well only way is to out in loading conditions.
And you will know which of the three combination is right.
-
All three configurations are exactly the same in terms of performance and current consumption... Will just pick up one of them...
Are you sure that a placement of the sensors inside of the motor is not a matter and just their polarity related to the magnets is the matter?
-
Do you mean the placement sequence? like A, B and C?
If so yes that matters.
I just labeled the placement sequence when removing the sensors.
Otherwise I really don't how to determine the placement sequence.
-
Do you mean the placement sequence? like A, B and C?
No, I'm not about the sequence... I'm about the placement... The sensors might be placed either very close one from another (even on the same PCB) or even on the opposite side of the wheel (120deg one from another) or any another angle... So, is the placement the matter or just the sensors' polarity regarding the magnets (let's assume that the sequence is the same in both cases).
-
Aaha well when opened the MP III I see only three slots where I can mount the sensors.
Your motor has more sensors mounting slots?
Yes I think the distance between the sensors matters, because of the timing for the controller.
Maybe can search on internet for more information?
My knowledge is very low at this issue.
-
Yes I think the distance between the sensors matters, because of the timing for the controller.
I'm not sure for that since a speed of the wheel/motor vary all the time and the controller should be able to follow these changes... I guess that only sensors config (60 or 120) and the sequence is a matter, not the placement... Again, It's only my guess...
