    Undergrad Calculating Efficiency of a DC Motor: How Do I Determine In and Out Values?

    So... would it be Power In = PE/T = mgh/t ? and Power Out = torque x RPM ? ? (The original equation is what my teacher gave me) haha

    Undergrad Calculating Efficiency of a DC Motor: How Do I Determine In and Out Values?

    Hi I am trying to calculate the efficiency of my DC motor. I know that efficiency is: Power Out / Power In * 100 I have been told by my teacher that Power In is calculated by the following formula, Power In = Power * Time And Power Out is; Power Out = Mass * Gravity * Height...
