lamina hydraulic motors have a “letter-number-letter” designation that indicates the type of motor. Size of gerotor , and mounting method required . for example : a motor having a 1/2 inch gerotor and requiring flange mounting short shaft, would be idicated as A50F
order motor with optional features according to the following suffixes:
“-T” Tumed down flange
“-2-bolt” oval flange
“-4-bolt ” square flange
“-A” aluminum round flange
“-TA” aluminum tumed down flange
“-1” one flat on shaft
“-2” two flat on shaft
“-DT” shaft end tapped
“-K” longer key
“V” with viton seal
refer to example on bottom of page 2
when selecting your motor for a specific application ,you must remember that the peak motor torque and RPM must be sufficient to meet the most severe demands of the application .
The operational characteristics of various hydraulic motors are given in the tables to permit easy and quick selection of proper motor for each application. For accurate selection be certain to measure PSI across the motor . this will eliminate any error due to hydraulic system losses.
To order motor with a 2-1/6 inch shaft ,order as FMO suffix (foot motor only).
From the tables you can determine what is required of the hydraulic system (GPM & PSI)if you know the motor torque and RPM required by the application . Also ,if you know the GPM and PSI delivered to the motor by the hydraulic system ,you can quickly select the right motor to deliver the torque and RPM required.
CALUCLATING HORSEPOWER
HP= （TORQUE×RPM）/63025
On this table you can find motor torque and RPM for known GPM and PSI-read across from GPM and down from PSI
Example : in a hydraulic system delivering 6 GPM at 800 PSI –an A125 motor will operate at 333 RPM and deliver 318 inch-lbs .of torque
CALUCLATING HORSEPOWER
HP= 318×333 /63025=1.68 |
