Alternative to Hall Effect Sensors for high speed rotation?
Alternative to Hall Effect Sensors for high speed rotation?
(OP)
Hi -
I think the title is descriptive enough - I'm looking for something other than hall effect sensors to accurately determine rotational position at speeds up to 45000 RPM, and be relatively economical... I am currently using 3 hall sensors to drive a brushless motor and would like to look into any creative alternate solution.

My company has recently developed a simple and inexpensive sensorless drive for bldc motors that would appear to be a solution to your requirements. Let me know if you want more information and I can post a URL to my company.
