Spindle HP calculation for milling ... It is basing power requirements solely from the feed, WOC, and DOC. I am not sure I can agree with that. 03-15 ... What isn't exactly accurate is the output curve for the spindle motor. It may not develop the needed torque at a low rpm for example. 03-15-2010, 12:54 PM #5. Gary E.

P = Power [kW] T = Torque [Nm] N = Engine rotational speed [rpm] 1 PS = 0.73549875 kW = 0.986320 hp (SAE) Some example engine torque and rpm numbers are interesting to gauge the range of values. You can convert the torque to power given the quoted engine speed. However, most engines generate peak power at a different engine speed to …

The tractive pull multiplied by the drive pulley radius will give you the load torque. There is no short cut for deciding the load torque. This cannot be calculated from motor side. 5) Having decided the load torque, you can decide the required power at motor shaft, available motor size, gear ratio and so on.

Hi guys I need a motor for my project, but I´m not quite sure if my calculations are correct. I need a motor to drive 10 kg on a linear slide, where the friction constant is 0.1. The motor will drive a belt the the object is fixed to the belt. To calculate the force required to move the object: F = m * g *u, F = force, m = mass of object, g = gravity constant, u = friction.

Ball Mill Power Calculation Example #1. A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80% passing ¼ inch (6350 microns). The required product size distribution is to be 80% passing 100 mesh (149 microns). In order to determine the power requirement, the steps ...

Milling Horsepower Calculator Calculate the horsepower required for a milling operation based on the feed rate and depth of cut, which are used to determine the material removal rate (or metal removal rate). Also required is the unit power, which is a material property describing the amount of power required to cut that material.

How to Calculate Power From Torque | eHow. Torque is the rotational force applied on an object, often measured in pound-feet, or lbf-ft. However, in order to calculate the power from torque, you also need to know the speed at which the motor is rotating, which is usually measured in rotations per minute, or RPMs.

Thus the power to drive the whole mill. = 49.5 + 66.0 = 115.5 h.p. = 86 kW. From the published data, the measured power to the motor terminals is 103 kW, and so the power demand of 86 kW by the mill leads to a combined efficiency of motor and transmission of 83%, which is reasonable.
