One partner all over the world
Hägglunds Drives
is the worlds leading
manufacturer
of heavy duty
hydraulic drive
systems. If
what you need
is low speed and
high torque, then
Hägglunds Drives
should be your partner.
If what you need is a durable
drive system that will work under
the toughest conditions with a minimum
of maintenance, then Hägglunds Drives should be your partner. We develop, manufacture
& market complete drivesystems and components of the highest quality, based upon our
unique radial piston motors. Our industrial and marine customers are to be found all over the
world. They know that when they need solutions, support or service, they have in us a partner
they can trust. Hägglunds Drives main office and manufacturing plant is situated in Mellansel,
Sweden. In Addition Hägglunds is represented in 40 countries worldwide.
The content in this manual is subject to change without notice or obligation, unless

Features
High power capacity
The new Compact has a wider speed range than
any motor we have built before. It can work at high
speed and high pressure, check out the efficiency
curves on page 15.
Adaptable mounting
Even through we believe in standard solutions.
We also believe in adapting our products to our
customers needs.The new Compact can be mounted
in just about any way you want it.
High power/weight ratio
The new Compact with it´s small outer diameter and
low weight will give you a high power to weight ratio
that is extraordinary. This means great performance
but also lower energy consumption.
Insensitive to shock loads
The new Compact is small and light but at the same
time tough and insensitive to shock loads. The new
Compact has everything you have come to expect
from a Hägglunds motor - high torque, wide speed
range, shock resistant, easy to install, easy to
maintain, and as tough as they come.
- Only smaller!
Hole through motor centre
The hole through the motor centre is extremely useful
in some applications. For example with through shaft
for driving from both ends - or to gain access to the
machine to feed water or other medium through the
shaft.
Quick selection diagram for Compact motors
The diagram below represents the torque and speed, corresponding to a basic rating life L10aah= 20 000 h.
Oil viscosity in the motor case 40 cSt (187 SSU). When operating below 5 rpm, coated pistons or oil with
higher viscosity shall be used. Contact your Hägglunds representative.
For operation outside of or in the line
screened area, please contact your
Hägglunds representative.

Hägglunds hydraulic industrial and marine motor COMPACT is of the radial-piston type with a rotating
cylinder block/hollow shaft and a stationary housing. The cylinder block is mounted in fixed roller bearings
in the housing. An even number of pistons are radially located in bores inside the cylinder block, and the
valve plate directs the incoming and outgoing oil to and from the working pistons. Each piston is working
against a cam roller.
When the hydraulic pressure is acting on the pistons,
the cam rollers are pushed against the slope on the
cam ring that is rigidly connected to the housing,
thereby producing a torque. The cam rollers transfer
the reaction force to the pistons which are guided in
the cylinder block. Rotation therefore occurs, and
the torque available is proportional to the pressure
in the system.
Oil main lines are connected to ports A and C in
the connection block and drain lines to ports D1,
D2 or D3 in the motor housing.
The motor is connected to the shaft of the driven
machine through the hollow shaft of the cylinder block.The torque is
transmitted by using a mechanical shrink disc, or alternatively by splines.
The symmetrical design of the motor has made it possible to design it as a two displacement motor. This
means that two different displacements and speeds can be obtained for a given flow. To get the 2-speed
function, a motor prepared for two speeds has to be ordered together with a 2-speed valve.

Data
Rated speed1)
Rated speed is the highest allowed speed
for a charge pressure of 12 bar (175 psi)
above case pressure. When a closed loop
system is used, a minimum of 15% of oil is
to be exchanged in the main loop.
Max speed
Maximum speed is the maximum allowed
speed. Special considerations are nece-
ssary regarding charge pressure, cooling
and choice of hydraulic system for speeds
rated above.
Accepted conditions for standard type
of motor:
1. Oil viscosity 20 - 40 - 10000 cSt
(98 - 187 - 4650 SSU). See page 21.
2. Temperature -35°C to +70°C
(-31°F to +158°F).
3. Running case pressure 0-3 bar (0-45 psi)
Max case pressure 8 bar (116 psi)
4. Charge pressure (see diagram).
5. Volumetric losses (see diagram).
Definitions
1)Operating above rated conditions requires
Hägglunds approval.
*Related to a required charge pressure of 12 bar/175 psi for motors in
braking mode. (Special considerations regarding charge pressure, cooling
and choice of hydraulic system for speeds above rated, 4 ports must be
used for higher speed).
**The motors are designed according to DNV-rules. Test pressure 420
bar/6000 psi. Peak/transient pressure 420 bar/6000 psi maximum, allowed
to occur 10000 times.
***Speed above 280 rpm requires viton seals. Max permitted continues
case pressure is 2 bar.

When the motor is used flange mounted it is normal to use spline.To avoid wear in the splines, the installation
must be within the specified tolerances in fig. 4. If it´s possible, let the spline connection be filled with oil. If
the spline is not lubricated, there is a risk for wear and corrosion. If there is radial and axial force

Design of driven shaft end
on heavily loaded shaft.
Where the driven shaft is heavily loaded and is
subject to high stresses, for example for changes
in the direction of rotation and/or load, it is recom-
mended that the driven shaft should have a stress
relieving groove; see Fig. 7 and tables 4 and 6.
Normally loaded shaft
In drives with only one direction of rotation and/or
load where the stresses in the shaft are moderate, the
shaft can be plain, see Fig. 8 and tables 4 and 6.

2-Speed valve for Compact, type VTCA 600
The 2-speed valve is designed for use with Compact motors CA 50-CA 210. The valve has displacement
shifting function and is mounted directly on the motor. When ordering motor prepared for 2-speed function
the main rotation, clockwise (R) or counter clockwise (L), has to be specified.
Displacement shift when motor is running is allowed for speed up to 30 rpm and max high pressure
150 bar (2175 psi).
The valve is available in three main designs:
VTCA 600 0 H: Hydraulic operated displacement shift.
VTCA 600 0 E: Electric operated displacement shift, 24 VDC.
VTCA 600 B E: Electric operated displacement shift with brake control function, 24 VDC.
With a two-speed
valve mounted on
the motor and the
oil supply connected
to P give a counter
clockwise rotation
direction on a motor
sign marked "L", see
fig. 17.
If the motor sign is
marked "R" the motor
rotation direction is
clockwise, see fig.

Accessories
Cross-over valve, COCB 1000 Emergency stop manifold, VECA
The VECA manifold can be mounted directly on
the Compact motor. The VECA manifold can be
con-verted for either clockwise or counter clockwise
motor shaft rotation.The VECA manifold gives a very
quick stop and can be integrated in most common
control systems. Screws and O-rings are included
in delivery.
The valve is designed for use with Compact motors
CA 50 - CA 210. The valve is bolted directly on the
motor, and the valve protects the motor and system
from too high pressure, if the motor is suddenly
stopped. The relief valves have a standard pressure
settings of 350 bar (5075 psi), but are fully adjustable
between 50 bar (500 psi) to 350 bar (5075 psi).
Screws and O-rings are included in delivery.

Flushing of motor case
The Compact motors have very high total efficiency, and they are now frequently used in applications
with high power. To avoid high temperature in the motor case the heat must be cooled away, because
Max power without flushing
CA 50/70 60 kW (80 hp)
CA 100/140/210 120 kW (160 hp)
high temperature gives lower viscosity and that
gives reduction in basic rating life. Low viscosity
also gives reduced permitted output power from
the motor.
- For continuous duty in applications with an
ambient temperature of +20°C (68°F), the
motor case must be flushed when the output
power exceeds the values shown below.

Diagrams for Compact
Volumetric losses
Valid for an oil viscosity of 40 cSt/187 SSU,
the diagram 26 shows the average values.
When calculating volumetric losses using
other viscosities, multiply the value given in
the diagram by the factor K in diagram 20.

Torque arm is mounted at a = 0 mm on the motor.
Note: When Bracket mounted motor or higher external load, please contact Hägglunds representative.
Permissible external loads
- The bracket must be designed so it does not give
extra external forces to the motor.
Motor mounted in winch - reaction forces.
