Mar 21, 2009 Now the Haas Mini-mill can come with a 7.5 HP motor. But it has 33ft lb of torque at 1,200 RPM. I dont know if the Mini-mill motor is the same or equivalent to the VF-0 motor. If they ARE similar - that 7.5 HP is developed at 1200 RPM and would probably fall precipitously as the RPM increases.

Mar 21, 2009 Multiply this by 3 (3 flutes), the rpm you are going to use and you have linear feed rate. Multiply this by the section width and depth and you have metal removal rate (MRR). Multiply MRR times unit hp. (For aluminum, milling, this might be 0.4 hp in3/min) This is spindle hp.
Most electric motors are designed to run at 50% to 100% of rated load. Maximum efficiency is usually near 75% of rated load. Thus, a 10-horsepower (hp) motor has an acceptable load range of 5 to 10 hp peak efficiency is at 7.5 hp. A motor s efficiency tends to decrease dramatically below about 50% load.
Electric Motor power consumption Formula The total power consumption E (kWh) is equal to 0.746 times of multiplication of total operating hours t (h) in hour, the rated power P (HP) in HP and the X percentage of the load. E (kWh) 0.746 * P (HP) * X * t (h)
