60 rpm to 30 rpm

  1. Jul 21, 2015 #1
    I have a 12V, 066A D.C motor, and 60 RPM. Want to reduce the RPM (60 to 30.
    What should I need to do?

    The electric motor may, or may not, allow you to control the speed by controlling the volts supplied. Some motors allow this, some do not. You will have to investigate the nature of your electric motor to determine this. Then if the motor does allow this, can you supply different voltages?

    If not, then could you use gears?

    If he still wants good torque at half-speed, he would need to use PWM on his 12V supply, no?

    yup, that or gearing will be the 2 successful ways

    here's some good examples from eBay .....
