3 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 preassembled 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 screwnut 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 throughshafts are available so that process costs can be optimized. Motors with a blind hollow shaft are excellent candidates for applications where only short strokes are required. Unlimited stroke lengths are possible in motors with hollow throughshafts. Motors with hollow throughshafts also allows power or compressed air to be fed along the moving axis. SPINDASYN motors are available in convection or liquidcooled models. In particular, the liquidcooled 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 screwnut systems is 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.

4 Our expertise an 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 throughshafts or blind hollow shafts, so that there is the option of limiting the strokes or not. Energy efficiency Compared to hydraulic systems and linear direct drives, SPINDASYN offers significantly higher efficiencies. Thus the customer achieves a better overall energy efficiency. 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. High stiff The integrated bearing eliminates the need for shaft couplings and significantly reduces the number of bearing points required. With the stiff enclosure and the amply dimensioned powertrain components, the entire system provides extreme stiff. 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 stiff connection to the screw nut allows very dynamic controller settings to be used. Reduced design complexity The readytoinstall 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.

5 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 relubricated. Maintenancefree operation Since SPINDASYN uses hightorque motors with sealed enclosures, they are practically maintenancefree 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 relubricated. 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) Liquidcooled 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.

6 Functionality and applications. Horizontal configuration, hollow throughshaft, no limiting of strokes Antitwist 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 screwnut systems. The companion structure, makes sure that the motor and screwnut system are flush with each other and that no radial forces are present. Vertical configuration, e.g., stroke unit, press Screwnut system SKT motors are suitable for screwnut 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 costeffective. One motor on a stationary screw Multiple motors on a stationary screw, e.g., format adjustments

7 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 relubrication 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. There are heavy duty bearings for both force directions and heavy duty bearings the 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. pulling Direction of force onto motor hollow shaft D = pushing, Z = pulling, B = both directions ball bearing, R = both directions roller bearing Both directions pushing The direction of force is relative to the motor hollow shaft (threaded screw). Note that the forces are applied to the hollowshaft 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. Example for an electrical press: Pressing force: Stroke: Press stroke: Screw lead: Cycle time: Fp = 25 kn Sv =.5 m Sp =.1 m h = 2 mm t = 2 s Number of revolutions over press stroke: A = Sp/h A =.1 m/.2 m A = 5 revolutions From diagram: L1 = 38 million revolutions for 25 kn Number of cycles: Z = L1/A Z = 38 million/5 Z = 76 million cycles Service life: L1h = t * Z L1h = 2 s * 76 million L1h = 152 million s L1h = 42222h Service life [million revolutions] Axial force [kn] F max_stat [kn] Life of Abearing (L1) for various axial forces Fa in [kn]

8 SPINDASYN hollow shaft motor in connection with screwnut 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 stiff connection to the screw nut allows for better dynamic performance. With the SKT series, the dynamic performance, torsional stiff 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 hollowshaft flange and screw nut. The screw nut is fastened to the hollowshaft flange using a matching adapter (to be ordered separately). An exception to this is the SKT7 motor where the hollowshaft flange is designed to fit a DIN 6951 flange nut. The dimensions for choosing screw nuts are shown in the following overview.

10 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 liquidcooling. Since liquidcooled motors allows for higher power densities, they are a good choice to achieve faster cycle times, for instance. A hollow throughshaft at the end of the motor provides sufficient room for screw strokes of unlimited length as well as for a multiturn absolute encoder.
