what to change?

[Anonymous]

Hello professionals,

   

I have a question on FOC sensorless Bldc control. Can anyone please tell me what do we need to change in the program or in the parameters if I want to get output of the motor with low speed and with high torque?

       

Thanks

Hi,

   

Since at low speed back emf position detection will not work. Low speed is not enough to generate the required feedback.

   

Please find below appnote explaining how this can be realized.
