Torque amplification

  1. Feb 9, 2015 #1
    In torque amplification, torque is multiplied without change in its input speed. Then this amplifier if coupled inbetween a motor and gene
    rator would it not be a over unity machine?

    No, that is not correct,
    P=T*theta
    If power is constant then torque decreases as RPM increases.
    Pay attention next time you ride a bike and change gears.

    Thank you for your reply. What you have said is true for torque multiplication using speed reduction gear box. In case of torque amplification, torque alone is amplified without change in speed. Please look for mechanical torque amplifier in your search, you would understand my query. Thank you.
