Review SPS-Fair Nuremberg

At the end of November, it was time for the annual SPS IPC Drives in Nuremberg. The Fair for automation is one of the most important and biggest fairs of it kinds. For Kählig Antriebstechnik GmbH this fair is also the main fair of the year. Therefore KAG focus on this fair.

This year´s SPS IPC Drives was all about “intelligence“ for KAG drives. KAG developed for nearly all own DC drives integrated electronics which gives the brushed and brushless drives „intelligence“. They communicate through CAN Bus with various protocols. The electronics are able to perform all common controls and plenty of additional functions. Since the release a lot of solutions in the agriculture, rail technology and building technology could be realized.

These solutions and the possibilities created a lot of interest at the fair. Additional to the samples shown on the fair, the new designed KAG-Folder supported the many conversations. All folders can be found at

To sum up, the fair was a big success for KAG. We had a lot of interesting conversations and contacts with promising new projects. In 2018 KAG will also be represented at the SPS IPC Drives in Nuremberg.

Product News: new M50 range and M80 12V High Performance Version

M50 range

With the additional motor sizes M50x28/I and M50x65/I, KAG is introducing two motors in addition to the existing product program, which close the power gap between the M48 range and M63 range. The new M50x65/I motor provides a 7% higher output power, compared to the M48x60/I and even reaches the output power of an M63x40/I motor. Therefore, the choices of an optimal motor for customer applications requiring power of about 50 W have been effectively extended.


M80x80 in a 12 V – High Performance Version

Kählig Antriebstechnik has extended the M80x80/I with a 12V-version with a higher power output. Until now a rotation speed of only 1,800 rpm with 70 Ncm could be produced. Now KAG have the opportunity to provide a 12V-winding, which delivers a rotation speed of 2,800 rpm and a torque with 70 Ncm.

KAG presents itself as innovative at the SPS trade fair in Nuremberg

Hannover, 19.11.2014. In hall 1 at the SPS IPC Drives 2014, KAG presents among others forward-looking electronics, which allow a high degree of individualisation for the customers. “With our offer, we address especially anyone interested from the field of medical technology, agricultural economy, door automation as well as from the leisure sector”, explains André Harstrick, the Marketing and Sales Director of KAG. The company for engine and drive technology presents itself both flexible and innovative on these fields. “Our specialists develop the suitable solution for practically every request”, tells Harstrick. A highlight on KAG’s exhibition stand is for example the result of a cooperation project, at which KAG took part as a drive specialist: the prototype of a knee orthosis drive. It works by means of an active electrical drive, reduces the energy demand when walking and contributes in this way to increase significantly the mobility. Also in the field of applications, KAG shows innovating spirit again. Visitors can get informed about the different options of the new CAN bus capable electronics i42, i42dc and i63, as well as various other application possibilities. Already now, a strong interest is shown in the new brushless motors of the series ECMa63, which are likewise exhibited at the SPS this time. For those who want to convince themselves in addition of the flexible applications of KAG Antriebstechnik, it will be best to let themselves demonstrate by the sales representatives from Hannover how easily tailor-made products by KAG can be found now using the new complete catalogue and the KAG Drive Configurator. “For us, it is important to know which solutions our customers need – and of course to be informed about the market situation”, says Harstrick. “The SPS offers a stage for this purpose.”

We look forward to your visit in hall 1, stand 454!

A new compact drive with integrated CAN bus control

From track to track more efficiency in agricultural technology

In order to optimize the dosage of the fertiliser or the seeds, KAG has developed a new drive with integrated CAN bus control. Meanwhile, the combination of motor and gearbox with integrated electronics has successfully passed all testing phases. Currently, the pilot series is in the field test. Thus, a KAG DC motor with a universal multi-master field bus system is available for the first time, where the software can be adapted individually for each manufacturer with little effort – and this motor thrills with many other advantages.

Today, newest technologies allow an ever faster and more and more efficient work in the agricultural sector. KAG supports this progress with drives that are already established in the international agricultural technology and works with full stretch on innovative developments in order to accelerate work processes and to reduce the energy demand at the same time.

Custom-made solution

“Our current project is about a gear motor with integrated CAN bus control, which is responsible for the efficient dosing of the seeds in a singe-grain sowing machine”, explains Andreas Schwerdtfeger, graduate engineer and developer at Kählig Antriebstechnik GmbH. “The objective is that the work tool puts the grain of seed on the field to the exact position within a very short time.” This automation process is carried out by evaluation of sensors and by special (motor) software, which communicates with the superordinated “job computers”.

“What is special about our new gear motor with i42DC is that the integrated CAN bus control is based on the international standardised protocol EN 50325-4, and that we can integrate customer requests into the software. In this way, besides the custom-made motor (+gear) solution with, for instance, a high IP protection and/or stainless steel shaft, further possibilities for the adaptation to customer requirements are available.”

This universal electronics, serving as an interface, can be adapted by means of Software modifications to the customizable control of each manufacturer. Thus, the seed placement on the field becomes significantly more precise, fast and efficient.

Simple assembly tanks to Plug and Play

“Another big advantage of the electrification in agricultural machinery for this project is, besides the precise approach to each individual seed row, the modular fixation by ‘Plug and Play'”. “The drive can be assembled to the customer’s application directly out of the shipping box: push in the plug and get started! Previous hydraulic motors could contaminate the ground with oil in the event of a fault. In case that an electrical motor should ever fail, a simple exchange is a matter of minutes. Our drives have a very high quality and thus are extremely reliable. We set ourselves apart by the precise manufacturing of individual components, and so we realise a high accuracy of fit of the components, which supports the function of sealing elements and so protects the motor against the penetration of water”, tells Schwerdtfeger. The corrosion resistance, which is already very high (for example, motor housings are not chromed but realised in cathodic dip painting (CDP)) can still be increased by varnishing upon customer request.
