    Motor Rotating
AI Thread Summary
The motor connected to the MCU via an H-bridge stops rotating after a few minutes, likely due to insufficient power supply or overheating. The MCU restarts when the motor is connected, indicating a potential issue with power draw or circuit design. Suggestions include using separate batteries for the MCU and motor, and incorporating opto-couplers to isolate the circuits. Additionally, sharing the schematic and software could help identify if the H-bridge is being switched correctly. Providing more details about the setup is crucial for effective troubleshooting.

It's because it doesn't work.
 
What are all the reasons you know of that are not causing it to stop?

i tried to rotate the wheels of my robot but the problem is the MCU restarts again and again whenever connect motor and hbridge circuit and at last motor stop.may i know the reason for this?
thanks
 
Try using separate batteries for the MCU and the motor and also opto-couplers between the MCU's outputs and the motor.
 
share your schematic and software, maybe you are not switching the h-bridge correctly.

Excuse me, but this thread is reserved for clairvoyants and psychics. We don't need schematics or information about the problem.
