01-05-2012· The torque curve and power curve for a constant-torque spindle. Figure 2 shows the torque and power curves for a spindle motor with constant torque followed by constant power. This kind of design is more common for spindles intended for use in the lower speed range, and, typically, the torque is higher.

Example - required Torque to produce Power. A machine rotates with speed 3000 rev/min (rpm) and consumes 5 kW. The torque at the shaft can be calculated by modifying (3) to. T = P / 2 π n. = (5 kW) (1000 W/kW) / 2 π (3000 rev/min) / (60 sec/min) = 15.9 Nm. Mechanics - Forces, acceleration, displacement, vectors, motion, momentum, energy of ...

08-01-2021· Torque Calculation From The Data Above About Spur Gears. We stated the relation between torque and power. And you can easily calculate the torque of an individual gear if you know the power transmitted between gear sets and the diameter of this individual gear. Torque Calculator For An Individual Gear

08-05-2017· 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.

as it receives kinetic energy from the surrounding air[3]. It can be shown[2] that under optimum conditions, when maximum power is being trans-ferred from the tube of air to the turbine, the following relationships hold: u2 = u3 = 2 3 u1 u4 = 1 3 u1 A2 = A3 = 3 2 A1 (6) A4 =3A1 Wind Energy Systems by Dr. Gary L. Johnson November 21, 2001

12-04-2018· The motor power increases with RPM at a similar rate to the preload losses which semi-cancels out to give a net power at thet tool of around 150-200W. I calculated torque from the RPMs and power. The motor seems to have good low end which drops off to a relatively consistent ~8in*lb; This mill is wimpy and I need to fix the power at the tool ...

19-06-2015· Ball Mill Power/Design Calculation Example #2. In Example it was determined that a 1400 HP wet grinding ball mill was required to grind 100 TPH of material with a Bond Work Index of 15 (guess what mineral type it is) from 80% passing ¼ inch to 80% passing 100 mesh in closed circuit.
