Gear Motors ALM Series Product Range Bi-directional motors. Mono-directional motors. These motors are without external drain and can be used with counter-pressures of maximum 6 bars; they can be used in both left (ALM...S) or right (ALM...D) configuration. The available displacements for the ALM1 group are between 1.4 to 13.8 cc/rev, for the group ALM2 between 4.5 to 35.2 cc/rev while for the group ALM3 between 20 and 87 cc/rev. For applications that require counterpressures higher than 6 bar please contact jbj Techniques technical office, email: info@jbj.co.uk or telephone: +44(0)1737 767493. Produced in three different groups with very good power/weight ratio and power/size ratio allowing a wide range of displacements within each group (between 2.8 and 87 cc/rev). The wide range of allowed speeds, the excellent functionality also on their use in series, with strong counter-pressures and limited drain, give to motors of the ALM series very good characteristics even starting under load. The drain is always external and it is through a thread port on the cover. Arange of flanges, shafts, inlet and pressure ports are available. 7 www.jbj.co.uk/gear-motors.html #DriveLineHarmony 1.4 2.1 2.8 3.5 4.1 5.2 6.2 7.6 9.3 11.0 ALM1 Series 4.5 6.4 7.08.3 9.6 11.5 14.1 16.0 25.5 28.2 ALM2 Series 23.7 21.1 17.9 20 22 26 33 39 44 52 78 87 ALM3 Series 71 61 3 Displacement (cm /rev) "H"Version suitable for fluid at low temperature.
