Hello, we have a school project to create a ESC. can anyone help me.
I was going to use the MC33035 IC but the motor runs on 48V. in addition the motor has hall sensor all ready attached

Serial: 167131
Thank you in advance

 

BLDC motors usually have the hall effect attached as they have to be phased with the stator windings for correct commutation.
You can always feed the output stage with 48vdc.
That is only a 2 pole motor, which quite unusual.

Thanks for the reply Maxheadroom, do you have any advice with how to build one, should I reduces the voltage to 24v and run the
mc33035 with the circuit provided and uses the needed mosfet with the provided spec.

 

You should be able to supply the top output FETs (bridge) with 48v and supply the logic with either a separate supply, or one derived from the 48v.
Use Google and you will most likely find a drawing where this has been done.
