18. www.hecogear.com LSHT Motor vs. High Speed Motor LSHT Motor –Single Reduction –Low Speed, Single Reduction Keeps Heat Low and Efficiency High –LSHT Motors are Usually Low Cost –Single Reduction and LSHT Motor Equals Efficiency of High Speed Motor with Double Reduction High Speed Motor –Multiple Reduction –High Speeds and Complex Gearing Develop More Heat and Efficiency Loss through Multiple Reductions –High Speed Motors are Usually Expensive –High Speed Motor is More Efficient, Double Reduction Reduces Efficiency

19. www.hecogear.com Heco’s Primary Competition HECO with Hydraulic Motor –Inherently Variable Speed –Small Package at Point of Use –Control of Acceleration to Maximize Component Life and Minimize Horsepower –Can be Used in Hostile Environments with No Special Precautions Electric Motor Gearbox –Complex and Expensive Speed Variation –Large Total Package Size at Point of Use –Electric Motor Requires High Horsepower to go from Zero to Full RPM in a Short Time –Special Motor Required for Wet or Explosive Environments

25. www.hecogear.com Sizing a Motor and Gear Reducer  Determine: –Required Torque –Required Output Speed –Available System Pressure Example: –33,000 in.lb. Output torque –40 RPM output –2,500 PSI available

26. www.hecogear.com Sizing a Motor and Gear Reducer  Calculate Total Displacement –Total Displacement = (torque * 2 pi) / pressure –Total Displacement = (33,000 * 6.28) / 2500 –Total Displacement = 82.9 in3/Rev.

27. www.hecogear.com Sizing a Motor and Gear Reducer  Calculate Flow Required –Flow = (In3/Rev * Rev/Min) / In3/Gal –Flow = (82.9 * 40) / 231 –Flow = 14.35 Gal Theoretical –Assume 85% Volumetric Efficiency 14.35 /.85 = 16.88 Gal

28. www.hecogear.com Sizing a Motor and Gear Reducer  Select Motor –Total Displacement / Gear Ratio = Motor Displacement –82.9 / 4.8 = 17.27 in3/Rev –82.9 / 6 = 13.82 in3/Rev –82.9 / 24.96 = 3.32 in3/Rev –82.9 / 31.2 = 2.66 in3/Rev

29. www.hecogear.com Sizing a Motor and Gear Reducer  Select Motor –Assume 90% mechanical efficiency of the motor and gear box combination and the displacements would become: –17.27 = 19.2 –13.82 = 15.35 –3.32 = 3.69 –2.66 = 2.95

30. www.hecogear.com Sizing a Motor and Gear Reducer  Single or Double Reduction –40 RPM * 24.98:1 or 31.2:1 would result in motor speeds at or in excess of 1,000 RPM – beyond the range of most LSHT motors and at the low efficiency end of the high speed motor range. –40 RPM * 4.8:1 or 6:1 would require motor speeds of 240 RPM and 192 RPM respectively which is in the best operating range of most LSHT Gerotor type motors

31. www.hecogear.com Sizing a Motor and Gear Reducer  Sizing Summary –Select a Model 20 Single Reduction –with a 6:1 Ratio –and use a 19 in3/Rev (approx.) LSHT motor –that is rated for 17 GPM –and 2500 PSI.
