I am not sure what you are saying. I referenced the MC33033 but the MC33035 would be a better part as it has F/R and brake. You posted several circuits which I cannot read but they look like just about everything you would need to make a sensored ESC. You do not need a micro as plain logic and analog circuits will do everything needed.

There are many other parts that do motor control so there may be better parts. Many CDROMs and disk drives use sensored BLDC motors so these parts are as common as dirt. However most are low power.

With the addition of the MC33039 it becomes a closed loop system or in our terms, 'governer mode'.

I checked and the results showed that the startup torque is too weak

I would like to suspend this thread until I successfully built the circuit, because it seems to have received little attention of people
thank you all

For car use (unlike planes - and boats), you want a sensored motor to ensure you have sufficient startup torque.

I am building my esc brushless for car.
it is version sensorless . it works well mode forward and reverse
. but still difficult braking mode
software of simonk, I will post here, hope someone can change program so that it can complete

thank a lot
