SPINDASYN
Hollow shaft motors.
With integrated heavy duty bearing.
Hollow shaft motors with
integrated axial bearing for
high forces: SPINDASYN
For applications requiring high forces and extremely accurate linear positioning, SPINDASYN hollow shaft motors from AMK are the perfect choice:
SPINDASYN is a pre-assembled turnkey solution. Each
unit consists of a powerful servo motor with an axial
bearing and an integrated multiturn absolute encoder.
Various adapter flanges are available for connecting to
different screw-nut systems. To meet the requirements
of customer specific applications, there is a variety of
motors and bearings in the SPINDASYN modular kits
according to screw lead and other parameters. In the end,
the customer receives a mechatronic system that is perfectly suited for the speeds and forces in the application.
Various motor designs with blind hollow shafts or hollow through-shafts are available so that process costs
can be optimized. Motors with a blind hollow shaft are
an excellent candidate for applications where only
short strokes are required. Unlimited stroke lengths
are possible in motors with hollow through-shafts.
Motors with hollow through-shafts also allows power
or compressed air to be fed along the moving axis.
SPINDASYN motors are available in convection or liquid-cooled models. In particular, the liquid-cooled models can be used to realize solutions with extreme short cycle times as they are
possible with hydraulic or pneumatic systems. The
excellent dynamic performance of the position controller allows for highly precise and reproducible processes.
The entire system of SKT motors and screw-nut systems are an economically superior alternative to
hydraulic and linear motors in applications with
high forces and varying speeds. SKT solutions can
greatly reduce your design and operational costs.
Our expertise – a advantage.
Flexibility via modular concept
The modular design of SPINDASYN linear
drives with respect to performance, screw
diameter and axial force allows them to be
specifically adapted to various applications.
There is the choice from models with hollow
through-shafts or blind hollow shafts, so that
there is the option of limiting the strokes or
not.
Extremely compact design
Since SPINDASYN includes an integrated
screw, an entire linear drive with minimal
dimensions can be designed. All of the
functional elements such as the servo motor,
bearing, DIN fitting for screw nuts, holding
brake and encoder system are concentrated
together as a compact unit within a single
enclosure.
Energy efficiency
Compared to hydraulic systems and linear
direct drives, SPINDASYN offers significantly higher efficiencies. Thus the customer
achieves a better overall energy efficiency.
High stiffness
The integrated bearing eliminates the need
for shaft couplings and significantly reduces
the number of bearing points required.
With the stiffness enclosure and the amply
dimensioned power-train components, the
entire system provides extreme stiffness.
High dynamic performance
Since the design is extremely compact, the
moment of inertia is also very low. The servo
motor offers high power and acceleration
ratings as well as high overload capacity.
Of special note, the torsionally stiffness connection to the screw nut allows very dynamic
controller settings to be used.
Reduced design complexity
The ready-to-install unit consists of a servo
motor, heavy duty bearing and multiturn
absolute encoder and can be connected
directly to a screw nut.
IP54 protection rating
With IP54 protection rating, these motors are
also suitable for harsh environments.
Installation at any location
Fitted with sealed bearings, SPINDASYN
units can be installed in any location.
According to customer application, the
bearings can also be re-lubricated.
Maintenance-free operation
Since SPINDASYN uses high-torque motors
with sealed enclosures, they are practically
maintenance-free and offer high availability.
The integrated temperature sensors protect
the motors against thermal overloading.
Depending on the lifetime lubricated angular contact ball bearings and tapered roller
bearings may have to be re-lubricated.
Heavy duty applications and high
speeds
SPINDASYN hollow shaft motors are an
efficient alternative to existing hydraulic solutions or linear drives in applications where
high loads have to be moved at various different speeds.
Highest power density through liquid
cooling (optional)
Liquid-cooled motors are compact in design
and offer higher dynamic performance
through less moving mass. Since the motors
weigh less and are smaller in size, they are
also easier to install.
At a glance, this means:
} Highest productivity
} Outstanding process control
} High precision
} Very high efficiency
} Low energy consumption
High performance and productivity for:
} Injection moulding machines
} Blow moulding machines
} Extruders

Functionality and applications.
Horizontal configuration, hollow through-shaft, no limiting of strokes
Anti-twist protection
In linear movements, the motor torque is
applied to the screw in the opposite direction.
This torque has to be braced by a linear guidance.
Companion structure
Radial loads or overturning torques reduce the
life of the screw-nut systems. With the companion structure, make sure that the motor
and screw-nut system are flush with each
other and that no radial forces are present.
Screw-nut system
Vertical configuration, e.g., stroke unit, press
One motor on a stationary screw
Multiple motors on a stationary screw, e.g., format adjustments
SKT motors are suitable for screw-nut systems such as roller or ball screws. As a rule of
thumb, roller screws can support larger forces
with smaller diameters while ball screws offer
better dynamic performance and are more
cost-effective.
Connecting flange to
central lubrication
The optional flange with stationary lubrication
bore can be easily connected to a central
lubrication system. In this solution, the screw
nut is continuously lubricated. A stop of the
machine for re-lubrication is not necessary.
Direction of force
The SPINDASYN hollow shaft motors are designed for very high axial loads. In versions with normal duty bearings, the motor
hollow shaft is designed to withstand both pulling and pushing forces. With heavy duty bearings, the specified direction of force
must be observed. The full axial force can only be applied in direction D or Z as specified. The direction of force can be found
in the product code on page 11.
Z (pulling)
Direction of force onto motor
hollow shaft
Both directions
D = pushing, Z = pulling, B = both directions
D (pushing)
The direction of force is relative to the motor
hollow shaft (threaded screw). Note that the
forces are applied to the hollow-shaft flange in
the opposite direction.
Designing bearings for SKT motors
For the dimensioning of the motor, a bearing life characteristic is provided for each motor type.
As the example shows, the bearing life can be calculated for a specific application.
Pressing force: Stroke: Press stroke: Screw lead:
Cycle time: Fp = 25 kN
Sv = 0.5 m
Sp = 0.1 m
h = 20 mm
t = 2 s
Number of revolutions over press stroke:
A = Sp/h
A = 0.1 m/0.02 m
A = 5 revolutions
From diagram:
L10 = 380 million revolutions for 25 kN
Number of cycles: Z = L10/A
Z = 380 million/5
Z = 76 million cycles
Service life: L10h = t * Z
L10h = 2 s * 76 million
L10h = 152 million s
L10h = 42222h
1000
Service life [million revolutions]

SPINDASYN hollow shaft motor in connection
with screw-nut systems.
The SKT principle of rotating nuts.
The screw nut is directly connected to the hollow shaft of the motor. The direction of rotation
of the screw nuts is converted to the linear
movement of the screw. Here, the screw only
moves linearly and does not rotate. The direct
drive of the screw nut offers many advantages,
especially compared to systems with rotating
screws. Thus, higher speeds of movement are
possible with the direct drive and the torsionally stiffness connection to the screw nut allows
for better dynamic performance. With the SKT
series, the dynamic performance, torsional
stiffness and precision no longer suffer the
negative effects from mechanical transmission
elements such as belt drives or couplings. The
motor bearings take up the high forces directly
so that heavy duty applications are possible.
Hence, machine design becomes much simpler.
The SKT series also allows for completely new
solutions to be developed, such as multiple
SKT motors on a stationary screw.
Interface between hollow-shaft flange and screw nut.
The screw nut is fastened to the hollow-shaft
flange using a matching adapter (to be ordered
separately). An exception to this is the SKT7
motor where the hollow-shaft flange is designed
to fit a DIN 69051 flange nut.
The dimensions for choosing screw nuts are
shown in the following overview.

Modular design of SPINDASYN hollow shaft motors.
The SPINDASYN series is a modular system.
First a motor can be choosen from the various
sizes available. Next, the SPINDASYN motor
can be modified for the specific forces, travel
distances or cycle times for a specific application by choosing from the various motor elements:
The motor bearings can be selected for
dynamic or heavy duty applications.
The active component of the motor can be
fitted with convection or liquid-cooling. Since
liquid-cooled motors allows for higher power
densities, they are a good choice to achieve
faster cycle times, for instance.
A hollow through-shaft at the end of the motor
provides sufficient room for screw strokes of
unlimited length as well as for a multiturn absolute encoder.
