I am looking at your 12v 150W 6812S motor with a shaft speed of 2800rpm. Can I drive a wheel off this direct with no gearing? Thanks, Andrew |

Andrew, you can but depending on diameter it will not be practical. Check out our robot speed http://www.technobots.co.uk/Technical/Calculators/Speed%20calc/Speed%20calc.htmc alculator and you will see what I mean - i.e. 200mm diameter wheel will give 65 mph. Practically, you need to gear down to give the desired speed which in turn will maximise the available torque. |

Colin, The RPM figure is the final drive speed so 'out of the gearbox'. |
