In some rare cases where a strange motor configuration or a motor with 6 or more poles is used, the motor inductance may be too low and a reactor may be needed. Running multiple motors on one drive may also result in a low inductance load and the requirement of an output reactor. Reactors at the drive output to reduce the effect of reflected wave:

The main advantage of an electrical drive is that the motion control can be easily optimized. Put simply, the system which controls the motion of electrical machines are known as electrical drives.A typical drive system is assembled with an electric motor (there may be several) and a sophisticated control system that controls the rotation of the motor shaft.

Motors are rated as one of four "design types" for their ability to endure the heat of that starting and pull up. In ascending order of their ability to start inertial loads, NEMA designates these as design type A, B, C, and D. Type B is the industry standard and is a good choice for most commercial and industrial applications.

If you opt for an electric grain mill, the wattage of the motor can determine how quickly it's able to grind grains. Typical models range from 300 to 1,200 watts. In general, the higher a mill's wattage, the faster it will grind your grains. Noise. Manual grain mills don't make much noise, but electric models can be pretty loud.

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size. ...

Overloaded motors can overheat and lose efficiency. Many motors are designed with a service factor that allows occasional overloading. Service factor is a multiplier that indicates how much a motor can be overloaded under ideal ambient conditions. For example, a 10-hp motor with a 1.15 service factor can handle an 11.5-hp load
