Reasons to Determine Motor Loading Most electric motors are designed to run at 50% to 100% of rated load. Maximum efficiency is usually near 75% of rated load. Thus, a 10-horsepower (hp) motor has an acceptable load range of 5 to 10 hp; peak efficiency is at 7.5 hp. A motor ’s efficiency tends to decrease dramatically below about 50% load.

Ball Mill Motor Power Draw Sizing and Design Formula. The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than 3.3 meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill. This is called the ball size factor S.

Electric motor bearing greasing requires the motor to be de-energized during the procedure. The result is reduced risk of excess grease entering the electric motor stator, due to Couetti Flow, and reduced viscosity, due to heat. Combined with safety issues, proper lubrication can maintain the electric motor reliability.
