The efficiency of electric motors is a great contributory factor to keep the production cost minimum. The maximum efficiency of electric motors is near 75% of the rated load. The efficiency of an electric motor decreases if the motor is run below 50% load. Similarly, efficiency decreases if the motor is overloaded. However, the range of ideal load for the peak efficiency varies at large according to brands and type of motors. For example, Crompton Greaves electric motors are trusted for delivering the best efficiency at a range of loads. Continue reading →
