FAQ

What is Mechanical Efficiency?
Mechanical Efficiency is the ratio between motor Output and Input is called efficiency which is indicated by the symbol of “η” and represented in the “%” and is represented as n=Ea*Ia/ω*τ or Efficiency =Induced voltage*Armature Current/Angular Speed*Torque. Angular speed is defined as the rate of change of angular displacement, Torque is described as the turning effect of force on the axis of rotation. In brief, it is a moment of force. It is characterized by τ, Armature Current is the Current which Flows in Armature Winding or rotating Winding of Motor or generator and Induced voltage when reactive power is given is the difference in electric potential between two points.
