Electric Motor Efficiency Decreases at Ellie Gillespie blog

Electric Motor Efficiency Decreases. A higher percentage represents a more efficient motor. Motor efficiency is a measure of the effectiveness with which electrical energy is converted to mechanical energy. Motor efficiency is the ratio between the amount of mechanical work the motor performs and the electrical power it consumes to do the work, represented by a percentage. The efficiency of an electric motor is defined as the ratio of the output power to the input power, typically expressed as a percentage. As the load increases, friction plays a smaller and smaller role in the overall efficiency. These motors were installed in 1972. Can anyone tell me how much the efficiency of a motor decreases over time? By adjusting the frequency supplied to the motor, vfds enable the operator to narrow in on the exact speed required, reducing energy consumption during periods of lower demand. Granted, other inefficiencies begin to occur at larger loads ($i^2r$ losses, copper losses, stray load losses, etc.).
