S12Z Integration based commutation

Hi,

 

We are using the S12ZVMC128 MCU and a BLDC 14 Pole motor of various speed/volt.

We are presently using BLDC software with the timing logic for commutation. This is where it looks for BEMF zero crossing and pre calculates the next commutation time.

 

Would it be better if we used the more advanced PMSM software ?

 

If not then can we get S12Z software which used the integration approach for commutation rather than the precalculation.

 

In our application the load changes rapidly. We think the integration approch will serve us better in dealing with the changing load.
