This video shows a brushless motor connected to the breadboard prototype of Open-BLDC (http://open-bldc.org) brushless motor controller. It is spun up with forced commutation (no commutation detection) and later it runs with sensorless commutation detection enabled. You can read more about it at http://www.esden.net/blog/2009/05/07/open-bldc-sensorless-commutation-detection/
