"When we consider an idealized energy transducer having no power loss in converting electric power into mechanical power" this gotten from Ford Professor of Mechanical Engineering Now my question is Doesn't that mean it could have 100% efficiency?? @StandfordUnive1 #effiency

Which we know is not possible due to friction in machines

@StandfordUnive1 Reading this page again on the MIT opencourse robotics chapter 2, I discovered that electric power and mechanical power must be the same. E.i = torque . Angular velocity. I guess that how we can get 100 percent efficiency
