I am in doubt with a motors operation, I am not sure whether this question could be asked here, I have a car wiper motor with two speed operation,It uses a PM dc motor with worm gear inside, so it is not possible to rotate the shaft when in stop condition so my question is there any way to act this motor as a generator??
please see the attached photo to see the gear mechanism of a wiper motor.
If i gave a pwm input inorder to create a small torque,and if i rotate shaft in same direction which is already rotating is it possible to rotate and harness energy.
