i m making a 3d printed wind turbine n as a generator i m using bldc motor. what i want is to give a signal from my phone so that resistance of motor increases n turbine stops moving even if there is wind. i searched the net n found about ESC but i dont know if it will work on motor which is giving output. thank u in advance.
You need to decrease the resistance to brake a motor (ie increase the current) since torque
is proportional to current.
You need to treat the turbine as a motor-generator and need at east 2 and possibly 4 quadrant control
to do this. To stop the rotor you'll need some means of sensing its position to drive the feedback
control loop. It will consume power rather than generating when doing this, note.
