Working of 2 phase BLDC

[Chinmay Gharat]

I need detailed (not mathematically) explanation of 2 phase BLDC motor,it's torque wave form and other such thing and also comparison between 3 phase and 2 phase BLDC.

 

[D.A.(Tony)Stewart]

Torque is proportional to Current
HP is proportional to V*I
Due to variation of torque between phases, more phases gives smoother torque.

You can search for waveforms depending on size and drivers using magnetic Hall sensors for commutation

ok thanks i also got most of the working in Atmel sheet on 2 phase bldc, i have one more question i want to seriously increase RPM of motor what can i do? does a force full constant current from constant current source help?
