My application needs a Hall sensor based BLDC motor control because of high startup torques and motor starting at Full loads conditions. I want to evaluate  Hall sensor based control using KV31x parts. I looked at NXP website and not able to find any Hall sensor based examples with KV series. I am very surprised that i couldn't find any examples of Hall effect based on KV series parts. All I found was sensorless FOC control.


Some of our product required to run at constant RPM and some require Constant Torque, but these motors may have a very high startup torque, load and may hit stall conditions many times in its life time. I would like to evaluate both sensorless and Hall sensor control. I will use KMS for sensoless control, and i am currently need help with Hall sensor based control on KV series and i cannot find any reference examples on any KV  tower boards.
