Can able to run the hall sensor based BLDC motor

[prasanthkumar170723]

Dear all,

My customized IPMSM BLDC motor have 10 pole and 12 stator slot, operating voltage 36V and nominal current 8A, hall sensors with 60 degree placement. I use the STM32G431R8T6 microcontroller for FOC operation and hardware is customized. I use the ST motor control workbench 5.Y.4 version. 

I able to run the motor with sensorless method and also able to increase/decrease the speed and torque. 

But, unable to run the motor with hall sensor based. I give the placement electrical angle is 180 degree based on the below calculation.

360 * pole = mechanical angle,

360 * 10 = 36 degree (mechanical angle),

electrical angle = (pole/2) * mechanical angle,

electrical angle = (10/2) * 36,

electrical angle = 180 degree.

By applying the above electrical angle parameters to ST MC WB and generate the code. Then flash the firmware. Initially the rotor oscillated, and I turns the rotor manually for few steps. The rotor tried to start rotating, but after 72 degree (2 steps) the rotor was stop. 

And I also watched the ST MOOC tutorial on youtube. But I didn't get any valid inputs from this video. video link https://www.youtube.com/watch?v=dt6bGpykerE&list=PLnMKNibPkDnFxzg5RExF_MNOxX6wfT95M&index=6

Please guide me to solve the issue

Thanks in Advance.

 Hello prasanthkumar170723,

I think there may be an error in your Placement electrical angle. It's determination is well described in MCSDK 6.1.2 documentation (Launch Workbench 6.1.2 -> About -> Documentations -> User Manual -> Hall sensor feedback processing)
