SPOOL VALVE HYDRAULIC MOTORS
GENERAL INFORMATION:
Orbit motors convert hydraulic energy (pressure, oil flow) into mechanical energy (torque, speed). Hydraulic orbit
motors operate on the principle of an internal gear (rotor) rotating within a fixed external gear (stator). The internal gear
transmits the torque generated by the application of pressure from hydraulic oil fed into motor which is then delivered via
the motor's output shaft. Orbit motors have high starting torque and constant output torque at wide speed range.
DISTIBUTOR VALVE
MLHM, MLHP, MLHR, MLHH, MLHPL, MLHRL, HP, HR, MLHRW, HW series motors have spool valve: the distributor
valve has been integrated with the output shaft. The cardan shaft rotates distributor valve and transfers mechanical
energy from gerotor set to output shaft. The valve has hydrodynamic bearings and has infinite life when load ratings are
not exceeded.
GEARWHEEL SET
There are two forms of gearwheel set:
- Gerotor set have plain teeth. These types motors are suitable for long operating periods at moderate pressures or short
operating periods at high pressures. MLHM, MLHP, MLHPL and HP series motors have gerotor set.
- Roll-gerotor set have teeth fitted with rollers. The rollers reduce local stress and the tangential reaction forces on the
rotor reducing friction to a minimum. This gives long operating life and better efficiency even at continuous high
pressures. Roll-gerotor sets are recommended for operation with thin oil and for applications with continually reversing
loads. MLHR, MLHRL, HR , MLHH, MLHRW and HW series motors have roll-gerotor set.
FEATURES:
Standard Motor
The standard motor mounting flange is located as close to the output shaft as possible. This type of
mounting supports the motor close to the shaft load. This mounting flange is also compatible with many standard gear
boxes.
Wheel Motor
W mounting flange makes the motors possible to fit a wheel hub or a winch drum so that the radial
load acts closer to motor bearings. This gives the best utilization of the bearing capacity and is a very compact solution.
Needle Bearing
MLHPN and MLHRN have an output shaft supported in needle bearing. These types motors are
suitable for operating conditions such us frequent start and stops, vibration on the shaft, high static and dynamic radial
loads in short operating terms.
Low Leakage
LL Series hydraulic motors are designed to operate at the whole standard range of working
conditions (pressure drop and frequency of rotation), but with considerable decreased volumetric losses in the drain ports.
This motors are suitable for hydraulic systems with series-conected motors with demands for low leakage.
Low Speed
LSV feature optimizes the motor for low-speed performance. Motors with this valving provide very
Valve
low speed while maintaining high torque. They are designed to run continuously at low speed (up to
200 RPM) at normal pressure drop and reduced flow. Optimal run is guaranteed at frequency of rotation from 20 to 50 RPM.
Motors with this valving have an increased starting pressure and are not recommended for using at pressure drop less than
580 PSI [40 bar].
Free Running
FR motors are with increased clearance at all friction parts, allowing the shaft to rotate more freely
with less mechanical drag. The increased clearance also improves lubrication of the wear surfaces of gear set and friction
parts. Additional advantages of “FR” version are prolonging of the life of the hydraulic motors at high speeds , as well as the
possibility to use them in systems with wide variation of the loading. FR Series motors are designed to operate with high
speed /over than 300 RPM/ and low pressure drop. Volumetric efficiency may be reduced slightly.
High Pressure
Shaft Seal
The high pressure shaft seals allow the motors to withstand high case pressures at high speeds
without external drain line.
Motors with
Speed Sensor
Motors are available with integrated inductive speed sensor. The output signal is a standardized
voltage signal that can be used to control the speed of a motor. The torque and the radial load of the
motor are not affected by the installation of speed sensor.

** Peak load: the permissible values may occur for max. 1% of every minute.
*** For speeds lower than given, consult factory or your regional manager.
1. Intermittent speed and intermittent pressure drop must not occur simultaneously.
2. Recommended filtration is per ISO cleanliness code 20/16. A nominal filtration of 25 micron or better.
3. Recommend using a premium quality, anti-wear type mineral based hydraulic oil HLP(DIN51524) or HM (ISO 6743/4).
If using synthetic fluids consult the factory for alternative seal materials.
4. Recommended minimum oil viscosity 70 SUS [13 mm²/s] at 122ºF [50ºC].
5. Recommended maximum system operating temperature is 180ºF [82ºC].
6. To assure optimum motor life fill with fluid prior to loading and run at moderate load and speed for 15-30 minutes.

1) Intermittent speed and intermittent pressure must not occur simultaneously.
2) Recommended filtration is per ISO cleanliness code 20/16. A nominal filtration of 25 micron or better.
3) Recommend using a premium quality, anti-wear type mineral based hydraulic oil, HLP(DIN51524) or HM(ISO6743/4).
4) Recommended minimum oil viscosity 70 SUS [13 mm²/s] at 122ºF [50ºC].
5) Recommended maximum system operating temperature is 180ºF [82ºC].
6) To assure optimum motor life fill with fluid prior to loading and run at moderate load and speed for 10-15 minutes.

APPLICATION CALCULATION
VEHICLE DRIVE CALCULATIONS
1.Motor speed: n, RPM
n=
168 x vml x i
Rin
n=
2,65 x vkm x i
Rm
vkm- vehicle speed, km/h;
vml- vehicle speed, mile/h;
Rm- wheel rolling radius, m;
Rin- wheel rolling radius, in;
i- gear ratio between motor and wheels.
If no gearbox, use i=1.
4. Accelerate force: FA, lbs [daN]
Force FA necessary for acceleration from 0 to maximum
speed v and time t can be calculated with a formula:
FA=
vml x G
22 x t
, [lbs];
FA=
vkm x G
3,6 x t
, [daN]
FA- accelerate force, lbs [daN];
t- time, [s].
2.Rolling resistance: RR, lbs [daN]
The resistance force resulted in wheels contact with 5.Tractive effort: DP, lbs [daN]
Tractive effort DP is the additional force of trailer. This value
different surfaces:
RR=G x r
will be established as follows:
-acc.to constructor's assessment;
-as calculating forces in items 2, 3 and 4 of trailer; the
calculated sum corresponds to the tractive effort requested.
G- total weight loaded on vehicle, lbs [daN];
r- rolling resistance coefficient (Table 1).

3.Grade resistance: GR, lbs [daN]
a- gradient negotiation angle (Table 2)
6.Total tractive effort: TE, lbs [daN]
Total tractive effort TE is total effort necessary for vehicle
motion; that the sum of forces calculated in items from 2 to 5
and increased with 10 % because of air resistance.
TE=1,1x(RR + GR + FA + DP)
RR - force acquired to overcome the rolling resistance;
GR- force acquired to slope upwards;
FA- force acquired to accelerate (acceleration force);
DP- additional tractive effort (trailer).
7.Motor Torque moment: M, lb-in [daNm]
Necessary torque moment for every hydraulic motor:
M=
N- motor numbers;
hM- mechanical gear efficiency (if it is available).
8.Cohesion between tire and road covering: MW, lb-in [daNm]
MW=
To avoid wheel slipping, it should be observed the following
condition MW > M
f - frictional factor;
GW- total weight over the wheels, lbs [daN].

9.Radial motor loading: Prad , lbs [daN]
When motor is used for vehicle motion with wheels
mounted directly on motor shaft, the total radial
loading of motor shaft Prad is a sum of motion force and
weight force acting on one wheel.
GW - Weight held by wheel;
Prad - Total radial loading of motor shaft;
M/R- Motion force.
