Dear sir/madam,
I have a small doubt in controlling BLDC motor, when motor is operated in 6-step commutation sequence using hall sensors as feedback, phase current shape should be in quasi-square wave.
When i am simulating, Bldc motor logic in Matlab waveforms are generating correctly but in Realtime hardware the waveforms are not in correct shape.
Current waveforms are attached to this thread.
I have tried at low speed also, at that time one commutation step signal is missing every time.
Regards,
krishna kanth.
