Trapezoidal Control of BLDC Motors Using Hall Effect Sensors

MOD6 CNT will gives 0,1,2,3,4,5 it does not mean it will rotate clockwise only.based on direction bit it will rotate you should add direction bit to mod6 cnt data. refer mc33035 you should understood trapezoidal commutation easily

hi Raghu

thank you very much for your reply!
please correct me if i am wrong , but the way TI implements MOD CNT is only one direction counter 0 1 2 3 4 5 0 1... so how can it reverse the direction ?
as i understand it : for every hall effect state there is 2 pwm options , one for reverse and one for forward direction , but if you reverse the direction the counter must count down.

Hi mark
Am not using this example code but i have done trapezoidal control of motors using hall sensor . we are reading hall data between 1 to 6 only but based on input command we are adding direction bit to the hall data
for example motor in reverse direction hall data is 3 we added 1 to the 011 then hall data become B(1011)
so we are taking MC33035 datasheet as reference and pwm switching can be written according to the mc33035 datasheet i.e BLDC motor controller.
please refer the datasheet it may help you

thanks

i will take a look!
