2 The Spool Valve Motors incorporate both valving and hydrodynamic journal bearings into a common shaft design. The Valve section ( Spool Valve ) can be optimized for low flow, low speed needs using a low speed Spool option to enhance smooth running Motors incorporate the proven orbit motor principle to provide high torque at low shaft rotation can be instantly reversed by changing direction of input/output flow while generating equal torque in either direction. The displacements available provide a wide variety of speeds and torques from any Spool Valve motor Low Speed High Torque Motors E-MOLO-MC001-E6 September 2011B-1B-2B-3B-4B-5 Features, Benefits, and ApplicationsDesign FeaturesSpool Valve technology is typically used where compact, economical solutions are most needed. Spool Valve Motors use a Spool Valve to precisely time and control flow through the orbit gear set (Gerotor or Geroler).

3 Inlet flow is directed into and out of the orbit set via slots in the Spool and passages through the motor housing. The result is a very cost-effective compact package suited to many application requirements. The three primary components in the motor are the orbit star, drive and output shaft. H, S and T Series incorporate the Spool Valve and hydrodynamic bearings in the motor shaft. The W series is similar except a ball bearing is used for the front bearing for increased side-load capacity. Due to its compact size and high speed capability, the J Series is unique and utilizes a separate dedicated Spool and Spool Valve drive. All Motors utilize eaton s constant-clearance Geroler technology except the H Series, which continues to use the time-proven H motor gerotor set. These Motors all use a three-zone pressure design consisting of three unique pressure areas: 1) inlet, 2) return, 3) case.

4 This provides the capability to limit motor case pressure and allows the use of several case pressure options for extended shaft seal and thrust bearing Proven Orbit motor Principle Hydrodynamic Journal Bearings Constant Clearance Geroler Three-Zone Pressure Design Reduced drive running-angle High-pressure seals Modular designBenefits Compact, powerful package Infinite bearing life (at rated loads) High efficiency Increases shaft seal & bearing life Smooth operation, increases drive life Reduces leakage Design flexibility Economically tailored solutionsApplications Harvesters Augers Spreaders Machine tools Conveyors Winches Turf care equipment Food processing Aerial Work Platforms Anywhere a compact drive with high output torque is neededBelow is a quick-guide to help select the proper motor for your application.
