Read MoreIn an electric motor the mechanical power is defined as the speed times the torque. Mechanical power is typically defined as kilowatts kW or horsepower hp with one watt equaling one joule per second or one Newton-Meter per second. Horsepower is the work done per unit of time. One hp.
Read MoreCalculation of initial power requirements is often used as a preliminary step in motor or gear motor selection. If the mechanical output power required for a given application is known then the maximum or continuous power ratings for various motors can be examined to determine which motors are possible candidates for use in the application.

This would be for the short circuit calculation portion. The 25 impedance instead of the typical 17 for a single motor included allowances for the lumped multiple wire and component impedances of the smaller motors.

Read More2014-7-17the mill outside diameter. The mill out-side diameter is a function of the grind-ing process selected. Autogenous mills are the largest in diameter since the feed grinds itself. A semi-autogenous mill uses some metallic or ceramic balls to assist the grinding process and can be slightly smaller. Ball.
Read MoreIn many milling operations the cutting tool must step over and make several adjacent cuts to complete machining a feature. As a result a small cusp of material called a scallop will remain between these cuts on any surrounding walls or on the machined surface if a ball end mill is used.

The Motor and System Although a complete system analysis is beyond the scope of this paper when conducting a root cause failure analysis it is important to recognie that the motor is only one component of a system. Many factors affecting the system will also affect the motor and may contribute to the motor failure and vice versa.
Read MoreMilling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth such as an end mill or face mill. Calculations use the desired tool diameter number of teeth cutting speed and cutting feed which should be chosen based on the specific cutting conditions including the workpiece material and tool material.

If they ARE similar - that 7.5 HP is developed at 1200 RPM and would probably fall precipitously as the RPM increases.
