FOC SDK 4.3 | Motor Profiler | low power BLDC

Question asked by Gerber on Oct 9, 2017

We are trying to setup a small BLDC motor with the Motor Profiler utility.

 

-X-NUCLEO-IHM07M1

-FOC SDK 4.3

-Custom motor: 2 pole pair BLDC 18VDC, 2W @ no load, 4000 rpm

 

With this setup the Motor Profiler is not able to successfully finish the profiling sequence.

During the profiling cycle the motor is turning slower each profiling attempt during the determination of the electrical model. The sequence stops with the message: profiling sequence takes to long.

Why is the Motor Profiler utility not able to finish the profiler sequence using the BLDC motor mentioned above? Are there special modifications necessary running ‘low’ power BLDC motors?
