To manually calculate your power consumption, all you need is this simple formula: Calculate the watts each device uses per day. Convert watts to kilowatts. There are 1000 watts in one kilowatt. Determine the kilowatts an appliance uses per month. Figure out the cost by multiplying the kilowatts per month by your electric rate.

Calculate the total power consumption of the 3 Phase 30HP motor is operating for 38 days at 70% of the full load and the motor is operated at 14 hours per day. Step1: First calculate the total number of hours. T (h) = 38 * 14 = 532 hours. Use our power calculation formula, E (kWh) = 0.746 * 30 * 532 * 0.7 = 8334 kWh.

sources present in this type of power generation. About 1000 MW e of ORC power is installed world-wide, and the technology can be regarded as mature. Recently proposed applications of the cycle include heat and power production from biomass combustion, or use in combination with high temperature fuel cells.

The ball mill motor power requirement calculated above as 1400 HP is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution. The ...

Calculation of power requirements is often used as a preliminary step in motor or gearmotor selection. If the mechanical 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.

The first step is to determine the drive mechanism for your equipment. Some examples are direct rotation, a ball screw, a belt and pulley or a rack and pinion. Along with the type of drive mechanism, you must also determine the dimensions, mass and friction coefficient, etc. that are required for the load calculation:

Machine coefficient 80%. （Answer） First, calculate the spindle speed in order to obtain feed per tooth. n=1000vc÷πDC= (1000×80)÷ (3.14×250)=101.91min-1 Feed per Tooth fz=vf÷ (z×n)=280÷ (12×101.9)=0.228mm/tooth Substitute the specific cutting force into the formula. Pc= (2×80×280×1800)÷ (60×106×0.8)=1.68kW Kc

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. Rod and Ball Mills by C.A. Rowland and D.M. Kjos @ Allis-Chalmers

The real load on the motor will be in accelerating the trolley from the stationary position. That is the part of the cycle that will determine the power needed from the motor. The actual top speed is of little concern in calculating power. The rate of acceleration is the important factor.
