As an innovative and quality-conscious company with over 1,000 employees developing and producing sophisticated linear and rotary drive systems from our production and logistic sites in Germany, Serbia, China and in the US, Dunkermotoren's global footprint is able us to offer you a worldwide operating partner for electric motion control drive solutions.
All of the components in our varied innovative drive solutions are designed and produced by us at Dunkermotoren. With drive components of up to 1,100W output power, integrated logic and power electronics and different field bus interfaces, our modular system offers you high flexibility.
Now part of the global AMETEK group, we can offer our customers the flexibility of a medium-sized company as well as the advantage of an international organisation.
With sales offices in Europe, Asia and in the US as well as more than 25 overseas representatives we guarantee proximity to our customers.
Brushed type DC motors from Dunkermotoren display low cogging torque, robust construction and low moments of inertia. Brushed DC motors can be combined with planetary and worm gearboxes, brakes and encoders of our modular system.
Brushless DC motors from Dunkermotoren offer high efficiency, good dynamics and high power density. Especially to be emphasised are our BLDC motors with intetegrated power and logic electronics. Brushless DC motors are easily combined with planetary and worm gearboxes, brakes and encoders of our modular system.
AC motors from Dunker motors are characterised by robust construction and are maintenance free over their lifetime.
Dunkermotoren's venetian blind drives are notable for rugged design and are maintenance free during lifetime. Versions of venetian blind drives are equipped with SMI-Technology.
Dunkermotoren develops and produces transmissions that are characterised by their smoothness, compact design and excellent efficiency. The product range includes planetary worm gears and the brand new SpiroTec gear, an angular gear with spiral-toothed wheelset made of hardened steel.
Worm gearboxes (SG) are noted for their very quiet running. The worm-gear shaft has bearings on both sides. The gear components, made of bronze or steel, and the lubrication ensure a long service life at the rated torque. In many applications, the right angle (outputshaft 90° to motor) is the optimum design solution. On request, wormgearboxes can be supplied with a hollow output shaft.
Planetary gearboxes (PLG) have the highest continuous torque capacity of all types of gearbox; at the same time they have a very compact design, low weight and excellent efficiency. In our planetary gearboxes is a variety of different materials depending on customer requirements and they are available with the continuous torque up to 160Nm, and many ratios from 4:1 to 710.5:1. Plastic or metal ring gears are available and form the housing of the gearbox. The planet gears are made of plastic, steel or steel sintered; straight or helical geared versions are available and the self-centering planet gears ensure a symmetrical power distribution.
The output shaft is made of steel and supported by double bearing so that it withstands high axial and radial loads. Ball bearings are used. For extreme loads special versions with welded shafts are also available. Our H(hybrid) planetary gearboxes are for especially quiet running, the planet gear of the first reduction being plastic and helical geared. In the PLG 60, the planet gears are of the second stage, and are also plastic and helical geared.
The gearboxes are customised e.g. for use in especially low ambient temperatures, or as high-power gearboxes with reinforced output shafts, or with special lubricants for very long service life. Please consider that an angular offset of up to ±7° is possible when the motor connector is placed towards the mounting holes of the gear box.
The new Spirotec gear (STG) is an angular gear with a spiral-toothed wheel-set that steadily generates high torques with a small centre distance in limited space. Both toothed parts are made of hardened steel so the gearbox works without wear; the lubrication remains free of contamination, helping preserve the sealing rings of the motor and output shafts. The resulting extremely long service life makes the SpiroTec highly suitable for combination with a BLDC motor for maintenance-free operation. The monoblock housing design ensures a particularly high meshing precision and an improved rigidity of the drive unit. The smooth running of the STG, which is ensured by the mathematically precise rolling motion is particularly noteworthy. Available with ratios of 5, 10 and 25:1, the STG 65 version comes with either a solid shaft with feather key or hollow shaft with keyway.
Dunkermotoren offer motors and gearboxes as well as control electronics and gateways. These include electronics for speed control and positioning to integrated PLC functions. Fieldbus and Ethernet-based communication interfaces are integrated in the drive.
Linear motors from Dunkermotoren offer highly dynamic motion and precise repeatability, with or without external encoder feedback. Available as actuators, components or easy-to-use modules with forces up to 1860N.
With smooth surfaces and a IP69K high-pressure wash-down rating, Hygienic ServoTube is ideal for material handling applications in the packaging, food and beverage, and Pharmaceutical industries. Hygienic ServoTube features a standard incremental encoder output and digital halls. The encoder delivers 10 micron resolution with 25 micron repeatability. The drive power interface is three-phase and can operate at 600V. Control of Hygienic ServoTube is possible with a wide range of standard amplifiers.
