Re: Sensored BLDC Motor Control Using dsPIC30F3010 - open loop
"sensored open loop" is an oxymoron.
Either you are running sensored or you are running open loop. It may be that the sensor feedback is still used for display only in open loop mode.
Why and how, exactly, did you "manually give hall sensor input for testing"? If you are running open loop then the feedback is irrelevant.
It sounds more like you are running in sensored mode, with no feedback, and the control algorithm is shutting down. Probably driven into saturation, trying to get the (non-existant) motor to turn.
