This stepper motor performs very well for my appliion and exceeded my expectations. I'm using these in a milling cnc I'm building to drive the axis ball screws and have been able to achieve speeds in excess of 2200rpm which with a 5mm pitch screw, translates into 11,000mm/min or over 400IPM.
Variable Speed Drives are used in a wide range of appliions, from small appliances to large mine grinders and compressors. About a third of the world's energy is spent on the motors that drive constantspeed centrifugal pumps, fans, and compressors, and the market penetration of inverter variable speed drive is still low.
The motor power draw required to turn a mill from rest to the operating speed includes the energy required for the initial starting torque and mechanical arrangements to rotate the mill. It is generally accepted that practical mill power (PM ) is a function of mill capacity and diameter,,P M = Mill Constant * (Mill Diameter ) n
