I have project that needs motor. Motor should only turn one direction and should rotate 1 or 2 times at a time. Motor speed needs to be low and torque must high. So I made this with stepper motor and stepper motor driver. I want to get system better.
I think this stepper motor and motor driver overkill because these cost a lot. I want to try to use DC worm gear motor instead of stepper motor and I want to drive this DC gear motor with half H bridge.
This motor has to stop always same spot. If we take the area where the motor starts to rotate as 0, the motor should always stop at 0 degrees.
If I use microcontroller with reed switch or hall sensor, I can do this I guess. I will connect magnet to the spot , where motor needs to always stop.
My question is, is there a way to do this without microcontroller ? Can I use these sensor without microcontroller and achieve to my goal? (I will use arduino for drive motor and other parts, I don't want to use microcontroller for stopping right spot.)
Since motor needs to rotate only one direction, half bridge is good for me.
