BE SERIES Ball Screw Driven Linear Actuators
Ball Screw Motors The BE Series products are designs based on the technology of hybrid step motors, ball screws and nuts. Provide high torque, high precision, and high efficiency to fit the application needs of designers. The combination of motor styles, motor sizes, ball screws and nuts, gives the freedom to use motors of different form factors to exactly fit in the application.
• Five frame sizes: NEMA 08, 11, 14, 17, 23 • Multiple motor lengths and motor sizes • Each frame size motor has a variety of lead options • Each frame size motor has a variety of nut options
The integrated ball screw actuators from PBC Linear provide a high quality innovate solution for high speed applications.
Features of BE Series
100 µ=0.003 µ=0.005 The ball screws of BE Series have outstanding 90 µ=0.008 µ=0.010 transmission efficiency of over 90%. Their required Ball screw 80 torque is just less than a third of what the lead screws Rotary Linear require. Therefore, it is easier to transfer a linear motion 70 into a rotary motion. µ=0.1 60 Efficiency η 50 (%) µ=0.2 Efficiency of ball screws Rotary Linear 40 µ=0.3 Acme screw 30 2 1 × T (Trapezoidal Normal operation P= screw thread) 20 T= Load torque kgf x cm 10 P= Axial external load kgf µ: Coefficient of friction = lead cm 012345678 9 10 Lead angle (degree) 1 = Efficiency of ball screws Mechanical efficiency of ball screws The all screws of the eries adopt a othic arch roo e profile its a ial clearance can be ad usted in a hi hly fine pitch as well as it can be li htly rotated.
