Question

Steval-SPIN3202 Hoverboard Hall Sensors bring Speed Feedback Error when Starting

Hello,

I'm new to STM32 programming but now I have already tried a lot and read quite a bit.

I have a Steval Spin3202 and Spin3201 board (just tested the 3202 yet) and i want to drive two unknown Hoverboard motors with the boards.

I have created a ST Motor Control Workbench projekt and selected the board.

I added the motor parameter and set the Hallsensor to 60° but already tried 120° as well.

Now i have the set the speed Sensing to Hall with 6 fault measurements before Error.

The Voltage Jumper is set to 3.3V and I see that the Voltage drops/rises when spinning the wheel while observing with the voltmeter.

When I start the motor i just see a very small "jump" and then the feedback occures.

I was hoping to have a better drive experience then with Sensorless measurement (that already kind of worked with a ramp and some adjustment, but not very well when Load was applied).

The motor has hall-sensors installed, but i also don't know the characteristics.

My motor should look like this -->

Dear Laurent,

sadly yes, but I made progress! Sorry for my late answer.

I have found out, that I had incorrect order of Hall1,2,3 and I checked it to see what values it does with an ardunino.

It lookes for me like a 120° placement:

H1 - 1 | 1 | 0 | 0 | 0 | 1

H2 - 0 | 1 | 1 | 1 | 0 | 0

H3 - 0 | 0 | 0 | 1 | 1 | 1

Also I connected Jumper J5,6,7 (Hall1,2,3) on the SPIN3202 board and opened J9,10,11 (Back-emf). When i press start the Motor just makes a sound but does not start. After a while it goes to error with Speed Feedback. When i turn the drive manually i get a measured speed rpm.

For me it lookes like the drive does not take enough Ampere to start. I checked with my lab bench power supply but the ampere did not go up above 0,2/0,3 (if i remember correctly).

I would need help what i could check or what I'm doing wrong.

Thanks for any help.

Additional Info:

I tried it with the 6 Step mode then the Motor kind of jumps but then goes in Fault with the Error "Over current" (but it didn't draw more then 0,6A accourdng to my power supply).
