is there any way to sense the magnetism produced in a dc motor to count the rotation?
 

Place a coil of wire near an opening of the motor housing. It could pick up some signal. Maybe magnetic field. Maybe sparks, etc.

Detect the waveform coming from your coil. To count rotations, you'll probably need to divide by the number of windings in your motor.
