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 effi ciency curves on page 15.
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 smal ler!
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.
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.

Functional description
Hägglunds hydraulic industrial and marine mo tor COMPACT is of the radial-pis ton type with a ro ta ting cylinder block/hollow shaft and a stationary housing. The cylinder block is mounted in fi xed rol ler bearings in the housing. An even number of pis tons are radially located in bores in si de the cy lin der block, and the valve plate directs the incoming and outgoing oil to and from the working pis tons. Each pis ton is working against a cam roller.
1
When the hydraulic pressure is acting on the pis tons,
2
the cam rollers are pushed against the slope on the cam ring that is rigidly connected to the housing,
3
thereby producing a torque. The cam roll ers transfer the reaction force to the pistons which are guided in
5
the cy lin der block. Ro ta tion therefore occurs, and the torque available is pro por tio nal to the pressure
10
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 dri ven machine through the hollow shaft of the cy lin der 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 dis pla ce ment mo tor. This means that two dif fe rent displacements and speeds can be obtained for a given fl ow. To get the 2-speed
function, a motor prepared for two speeds has to be ordered together with a 2-speed valve.

Defi nitions
Rated speed
Rated speed is the highest allowed speed for a char ge 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 nece­ssary regarding charge pressure, cooling and choice of hydraulic system for speeds
rated above.
Accepted conditions for stan dard type of mo tor:
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).

When the motor is used fl ange mounted it is normal to use spline. To avoid wear in the splines, the in stal la tion must be within the specifi ed tolerances in fi g. 4. If it´s possible, let the spline connection be fi l led with oil. If the spline is not lubricated, there is a risk for wear and corrosion. If there is ra di al and ax i al for ce on the shaft, the spline area in the motor shall be fi l led with oil. When the mo tor is assembled the splines must be greased with Molycote Long term 2. For production of the shaft, see 278 2230, 278 2231, 278 2232, 278 2233, 278 2234, 278 2235, 278 2236, 278 2238 or 278 2239. For control of spline see table 2.

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 recom­mended that the driven shaft should have a stress relieving groove; see Fig. 7 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 dis place ment shifting function and is mounted directly on the motor. When ordering motor prepared for 2-speed function the main rotation, clockwise (R) or counter clock wise (L), has to be specifi ed. 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.

Cross-over valve, COCB 1000 Emergency stop manifold, VECA
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).
The VECA manifold can be mounted directly on the Compact motor. The VECA manifold can be con-verted for either clockwise or counter clockwise mo tor shaft rotation. The VECA manifold gives a very quick stop and can be integrated in most com mon control systems. Screws and O-rings are included in deli ve ry.

Flushing of motor case
The Compact motors have very high total effi ciency, and they are now frequently used in applications with high power. To avoid high tem pe ra tu re in the motor case the heat must be cooled away, because
high temperature gives lower viscosity and that gi ves reduction in basic rating life. Low viscosity also gi ves reduced permitted out put power from the motor.

Choice of hydraulic fl uid
The Hägglunds hydraulic motors are primarily designed to operate on conventional pet ro le um based hy drau lic oils. The hydraulic oil can be chosen in consultation with the oil supplier or your local sales offi ce, bearing the following requirements in mind:
General
The oil shall have FZG (90) fail stage minimum 11 described in IP 334 (DIN 51354). The oil must also contain inhibitors to prevent ox i da tion, corrosion and foaming. The viscosity of mineral oil is highly dependent of the tem pe ra tu re. The fi nal choice of oil must depend on the operating temperature that can be expected or that has been established in the system and not in the hydraulic tank. High temperatures in the system greatly reduce the service life of oil and rubber seals, as well as resulting in low viscosity, which in turn provides poor lubrication. Content of water shall be less than 0,1%. In Industrial applications with high demands for
service life, the content of water shall be less than 0,05%.
Recommended viscosity
At operating temperature: 40-150 cSt/187-720 SSU.
Viscosity limits
Viscosity index = 100 recommended
= 150* for operation with large temperature difference
Min. permitted in continuous duty Min. permitted in intermittent duty Max. permitted
* Many hydraulic fl uids with VI-improvers are subject to temperary and per ma nent reductions of the viscosity. ** Low viscosity gives reduced basic rating life for the motors and reduction of max allowed power.
40 cSt/187 SSU 20 cSt/98 SSU** 10000 cSt/48000 SSU
Normal operating temperature should be less than +50°C (122°F)
Nitrile seals (std motor) Viton seals
Nitrile seals (std motor) Vition seals
Temperature limits
-35°C to +70°C
-20°C to +100°C
-31°F to +158°F
-4°F to +212°F
Fire resistant fl uid
The following fl uids are tested for Hägglunds motors (ISO/DP 6071).
Fluid Approved Seals Internal paint
HFA: Oil (3-5%) in water emulsion No - -
HFB: Inverted emulsion 40-45% water in oil Yes Nitrile (std motor) Not painted*
HFC: Water-glycol Yes Nitrile (std motor)** Not painted*
HFD synthetic fl uids
HFD:R - Phosphate esters Yes Viton Not painted*
HFD:S - Chlorinated hydrocarbons Yes Viton Not painted*
HFD:T - Mixture of the above Yes Viton Not painted*
HFD:U - Other compositions Yes Viton Not painted*
* Must be specifi ed in the order. **The motor must have synthetic oil for the axial bearing.
Environmentally acceptable fl uids
Fluid Approved Seals Internal paint
Vegetable */** Fluid HTG
Synthetic ** Esters HE Yes Nitrile (std motor) -
*Vegetable fl uids give good lubrication and small change of viscosity with different temperature. Vegetable fl uids must be controlled every 3 months and temperature shall be less than +45°C (113°F) to give good service life for the fl uid. **Environmental acceptable fl uid give the same servicelife for the drive, as mineral oil.
Yes Nitrile (std motor) -

Choice of hydraulic fl uid
Down rating of pressure data and basic rating life
Down rating of pressure, for motors used in systems with fi re resistant fl uids, the maximum pressure for motor given on data sheet must be multiplied with following factors: HFA-fl uid not fi t for use HFB-fl uid 0,7 x maximum pressure for motor HFC-fl uid 0,7 x maximum pressure for motor HFD-fl uid 0,9 x maximum pressure for motor
Down rating of basic rating life, for motors used in systems with fi re resistant fl uids, the "expected basic rated life" must be multiplied with following factors:
HFA-fl uid not fi t for use HFB-fl uid 0,26 x expected life with mineral oil HFC-fl uid 0,24 x expected life with mineral oil HFD-fl uid 0,80 x expected life with mineral oil
Filtration
The oil in a hydraulic system must always be fi lte red and also new oil from your supplier has to be fi ltered when adding it to the system. The grade of fi ltration in a hydraulic sys tem is a question of ser vi ce life v.s. money spent on fi lt ra tion. In order to obtain stated service life it is important to follow our recommendations concerning con tami na tion level. When choosing the fi lter it is important to consider the amount of dirt particles that the fi l ter can absorb and still operate satisfactory. For that rea son we recommend a fi lter with an indicator that gi ves a sig nal when it is time to change the fi lter cartridge.
Filtering recommendations
Before start-up, check that the system is thoroughly cleaned.
1. In general the contamination level in our motors should not exceed ISO 4406 19/15 (NAS 10).
2. For heavy-duty applications the con tami na tion level should not exceed ISO 4406 16/13 (NAS 7).
3. When fi lling the tank and motor case, we recommend the use of a fi lter with the grade of fi ltration
β10=75.
Explanation of "Grade of Filtration"
Grade of fi ltration β10=75 indicates the following: β10 means the size of particle ≥10µm that will be removed by fi lt ra tion.
=75 means the grade of fi ltration of above mentio ned size of particle. The grade of fi ltration is defi ned as number of particles in the oil before fi ltration in relation to number of particles in the oil after fi ltration.
Ex. Grade of fi ltration is β10=75. Before the fi ltration the oil contains N number of particles ≥10µm and after passing the fi lter once the oil
contains number of particles ≥10µm.
This means that number of particles have been fi ltered (=98,6%).
