Hello, I am a real newbie when it comes to electrical mechanics etc, so I be really happy for some help. I have a Tamiya electric pulley unit set up to form an aerial tramway. The trouble is that when I connect a battery to the electric motor, it runs too fast. The RPM of the motor is too much for a realistic tramway. I am using the smallest battery that will power the motor. It is a 1.5volt battery. I know gearing would normally be the answer, but there is not room for additional gears on the Tamiya kit and it is all custom built. I have my small pulley wheels driving the large pulley wheel, but the speed is just too fast. Can I buy some sort of power regulator to slow down the electric motor ? If I bought a smaller electric motor would that have lower RPM ? Any ideas would be most welcome. Thank you.
