only so please make sure not to apply the brakes when motors are
driving.
(Note2) In case of low pressure release type, brake release shall be conducted
by providing hydraulic oil pressured more than stroke end pressure and
less than 7.8 MPa (80kgf/cm2)
Please note that effective pressure is the differential pressure between
brake release and drain.
(Note3) In case of motors with H6-B as brake model code, release pressure is
provided from traveling counterbalance valve, and the brake is automatically released.

The M3B Series are variable displacement type motors
with the same rotary components of M3X Series which
enable the advanced low speed characteristic and high
speed operation.
The design of various displacement control is based
on current MB Series. The range of displacement is
100%–33% with 3 types of various displacement control
regulators. Electric displacement control is also possible.

New design which reduces pressure ripple and friction enabling expanded lower speed limit and smooth starting characteristics.
2. High-Speed Operation
M3B280

New materials and enlargement of variable displacement
range have enabled the higher maximum speed. The ratio of

(Note1) The regulator in M3B motor operates choosing the higher
pressure port between A and B port. If the servo pressure
does not hold more than 2 MPa, servo pressure must be
provided.
If you need to shorten the time of shifting displacement,
proper servo pressure must be provided. (Refer to below fig.)
(Note2) Pilot control section in M3B motor controls pilot second pressure negatively.
Negative displacement control of Code No.2-4 may be conducted by providing pilot second pressure directly without using solenoid operated switching valve or solenoid operated
proportional valve.
(Note3) Small displacement instruction must be provided on the pilot
control side before using automatic control operation. Automatic control operation precedes pilot control operation.
(Note4) The automatic controller of Code No. b and c operates
choosing the higher pressure port between A and B port.
The regulator operated by the differential pressure Ip1-p2I is
also available as optional function and if necessity arises,
please contact us.

Displacement varies in order to maintain the pressure in line with the load.
The motor maintains small displacement operation until the pressure increases to a certain point, and then shifting into a large displacement operation.

During small displacement operation, when the load increases and the
pressure reaches to a certain point, the motor shifts into large displacement
operation. Since then the motor maintains the large displacement operation
until the pressure declines to a certain point.

N・m
MPa
As shown in the right, the high pressure oil passes through
the inlet port (a) and flows into the cylinder block (2).
Hydraulic force thus acts upon the piston (4), generating an
axial force F. This force F is vector-analyzed through the
shoe (5) into force F1 which is perpendicular to the swash
plate (7), and force F2 which is a vertical force with respect
to the output shaft. The reaction force of force F2 is
transmitted via the piston to the cylinder block, generating a
rotational force which turns the output shaft.
These are 9 equally spaced pistons in the cylinder block.
The pistons connected to the high pressure inlet port
transmit rotational torque sequentially to the output shaft.
Reversing the flow of operating oil causes the output shaft
to rotate in reverse.
The theoretical output torque (T ) is obtained by the
following formula.

The semi cylindrical slide plate, positioned at the both sides
of the swash plate, supports the load, as a swash plate

controlling the oil supply to the chambers to adjust the tilting

This is a negative type, oil-lubricated, multi-disc parking
brake. Friction plates are cooled and lubricated by the drain
oil of the hydraulic motor. The braking operation is as
follows.
The friction plates (14) which are splined to the joint (11)
and the separator plates (13) which are splined to the valve
cover (8) are placed alternately. If not in operation, the brake
piston (10) is pushed leftward by the springs (3) and the
resultant friction force between the friction and the separator
plates restricts the driving shaft to rotate. On the other hand,
a release pressure larger than the spring force is applied to
the oil chamber (15) through the release port, the brake
piston (10) moves rightward and clearance is formed
between the plates. So the brake is released and the driving
shaft can rotate freely.

The semi spherical pivot ball, positioned at the both sides of
the swash plate, supports the load, as a swash plate
supporting mechanism.
The tilting angle of the swash plate diminishes by
supplying the oil to the chamber of a control piston
positioned at the swash plate. On the other hand, when oil is
not supplied to the chamber, swash plate is retreated by the
forces applied to the pistons and by the cylinder spring and
the tilting angle becomes maximum.

／CAUTION FOR HANDLING
WARNING
CAUTION
5.Oil filling and air venting
1.Operating fluid and temperature range
Please use antiwear hydraulic fluid as operating fluid.
Before operation, be sure to fill the casing with oil through the
drain port . Vent all air out of the motor and hydraulic circuit prior
to operation.
The insufficient amount of oil may cause the lubrication failure,
resulting in the seizure of internal parts. The volume of the oil is
shown in the SPECIFICATIONS as case volume.
The allowable ranges of operating fluid are as follows.
Viscosity：10∼1,000mm2/s(cSt)
Temperature：−20∼ ＋80℃
In case of using special fluid (Phosphate ester compounds,
water-glycol fluid, fatly acid ester compounds, etc.) please
consult Kawasaki for instructions prior to use.
WARNING
6.Parking brake
CAUTION
2.Filtration
For satisfactory service life of these motors application, the
operating fluid should be controlled cleaner than the cleanliness
level of NAS1638 Class9. Install a 10μm filter in the return circuit of
respective actuators.
WARNING

7.Radial and thrust load
3.Mounting
Regarding the mounting direction, please refer to the below list.
In case of the "Option" mentioned in the list, please consult
Kawasaki.
Alignment should be so carried out that the parallel error may be
held within ±0.05mm.

This brake should be used only for parking, are not for dynamic

adoption of the time delay valve should be taken to prevent the

WARNING
4.Drain piping
The motor's drain port, as shown in the following figure, should
be so located that the casing can be filled with oil.
Use a drain tube bigger in size than the motor's port. Keep the
casing pressure normally below 0.2MPa (2kgf/cm2) and below
0.6MPa (6kgf/cm2) even at the peak.
Bearing life against the radial load applied to the shaft is
shown in the Performance curve for each motor type. If load
point or load direction is different, please consult us.
Do not apply thrust load to the shaft of these motors.
Radial and thrust load may be applied to the output shaft of
the reduction gears. Please refer to P23 for the relations
between the radial load and the bearing life.
CAUTION
8.Cavitation
When the motor is operating in an overrunning (pumping) mode,
then to prevent the occurrence of cavitation, a positive boost
pressure is required at the suction port. The minimum boost
pressure requirement shown in the model performance data is
based on the regular operation. In case of a rapid change of the
flow volume, more boost pressure must be applied.
CAUTION
9.Back pressure
The lower of the two main motor ports pressures should always
be less than 2.5MPa (25kgf/cm2). Pressure higher than this could
cause a possible reduction in motor performance. In case of any
doubt please consult us.
