Determining Electric Motor Load and Efficiency
Reasons to Determine Motor Loading Most electric motors are designed to run at 50% to 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.

What Works | Grounding rings on plant motors mitigate ...
The 5,000-hp motor bearings failed regularly until an AEGIS iPRO Bearing Protection Ring (inset) at each end of the motor diverted damaging voltages. These on-site retrofits were accomplished without the need to decouple the motor from the mill, thanks to the use of a split-ring version of the iPRO.

How can I control an electric motors speed? | All About ...
I also wonder about the size of the ball mill, and in addition, 60 RPM is not slow. And 1800 RPM for a ball mill is far out of control and i an runaway condition. As all ready commented, it is the starting torque that is the problem. My suggestion is an induction motor and a mechanically variable drive to start slowly and then go faster.
