Greeting everyone,

Anyone has any idea on how to implement an electric brake for a small DC
motor driven by a H bridge mosfet arrangement. The normal running current
the motor consumes is about 300 ~ 400 mA at full speed and average load.

The problem is that the motor has a small flywheel attached to it which
keeps it going for a while after the supply has been shut off.

This is for a model train decoder and I'm trying to figure out how I'm going
to implement an emergency stop. The motor's speed and direction is
controlled by a PIC using PWM. Right now I dont have any plans of using back
EMF for speed control so I'm trying to find a braking solution that doesn't
use back EMF.

Thanks,

Shahid
