Rated Horsepower - an overview ScienceDirect Topics

hp = motor rated horsepower. 0.746 = conversion factor for hp to kW. Then, the horsepower ( hp) for a three-phase motor can be calculated as ( Vogelesang, 2008) (3.50) h p = V × I × E m o t o r × P F × 3 746. where. V = RMS voltage, mean of three phases. PF = power factor as a decimal.

7 Things You Should Know About CNC Machine Motors

2021-10-26  Horsepower and torque ratings alone don’t provide enough information to make an informed decision about a motor’s potential performance. Unfortunately, some CNC machine builders use off-the-shelf motors that may appear to have adequate HP ratings, based upon power consumption rather than actual output, and may not meet other important criteria.

Fractional Horsepower Motors - an overview

These are ball bearings and sleeve bearings, (sometimes called a bushing). Sleeve bearings are normally, but not always, used on small fractional-horsepower motors up to one-half horsepower. Ball bearings are used on larger motors, but they may also be used on smaller motors. Where there is end thrust on the motor, ball bearings are recommended.
