SUSTAINABLE TRANSPORT
ELECTRIFIED AND EMISSION-FREE
When it comes to meeting CO2 targets, electric mobility is the way forward. Electrification is gaining ground, not only for cars but also in the area of commercial vehicles in particular. KEB Automation’s innovative solutions enable the electronic operation of auxiliary systems in commercial vehicles and mobile machinery, while helping to reduce emissions at the same time.
Electromobility
One of the most important keys to a more sustainable future is the rapid implementation of the mobility transition. And this is not without good reason as in the European Union, transport is responsible for a significant share of all CO2 emissions and is the only area in which greenhouse gas emissions have increased in the past three decades. This is precisely where electromobility comes into play, laying the foundations for climate-neutral traffic. The number of newly registered electric vehicles is continuously increasing – and with it, the need for sustainable solutions for operating auxiliary systems such as air-conditioning and air compressors or hydraulic and power steering pumps. KEB Automation provides users with the necessary drives, controls and software solutions out of one hand.
The T6 APD provides a scalable and modular DC-AC inverter system with integrated power electronics, an intelligent mobile control unit and EMC filter solutions. It converts direct current from the HV-DC source into alternating current to drive electric motors. In addition, bistable brakes and clutches, for example in pick-up trucks or driverless transport vehicles, enable energy-free engagement/disengagement and hold devices and equipment in place with energy savings of up to 99 percent in battery-powered systems.

Drive solutions for auxiliary drives in e-vehicles
Commercial vehicles
The importance of CO2-free, environmentally-friendly mobility is constantly increasing, particularly in urban areas. For this reason, towns, cities and local authorities are pursuing different approaches in the attempt to bring about a tangible improvement in the quality of inner-city air, and a reduction of traffic noise. One solution in this context is the electrification of commercial vehicles. New and innovative drive solutions, for example in public transport buses, municipal vehicles such as waste collection vehicles or road sweepers, can alleviate the negative effects of noise and exhaust emissions for the environment and residents. So-called “last mile logistics” also offer great potential for reducing emissions through the creation of micro depots in urban areas and the use of electrified delivery vehicles. KEB's solutions in commercial vehicles
Mobile machinery
From construction machinery, excavators and ground equipment to mining or special vehicles, there is a wide range of mobile machinery and therefore tailor-made solutions are required when it comes to the electrification of auxiliary drives. The use of electric construction machinery and devices is increasingly in demand, particularly in urban areas. As this equipment does not produce exhaust or noise emissions, it protects users and is good for the environment. KEB provides drive solutions, such as those that take over the sustainable operation of heating, cooling, ventilation and air-conditioning systems in mobile machinery.

Agricultural machinery
How can the agricultural sector also take full advantage of electromobility? This is the question that virtually all manufacturers of agricultural machinery and attachments are asking. Whether we are talking about municipal vehicles, harvesting or forestry machinery, mowers and attachments, hay rakes or combine harvesters, in the wake of precision farming, digitalisation and, above all, automation, e-mobility is becoming increasingly relevant in agriculture. For the electrification of auxiliary systems, KEB offers a wide range of solutions for PTO concepts with power electronics in mobile electrical agricultural machinery.

Electrical engagement and disengagement
Electromagnetic clutches, brakes and combinations in the automotive sector have a positive impact on saving fuel, reducing CO2 and optimising efficiency, and offer an inexpensive alternative to electric auxiliary drives. For these tasks, KEB offers a wide range of technical solutions from switching via the electromagnetic field, permanent magnet and spring-tension units, to bi-stable flip-flop units, optimized for energy consumption. The automotive products are developed, designed, specified, manufactured and certified in accordance with IATF 16949:2016. More about electrical engagement and disengagement

Safety and Security
Our development phases depend on ASIL and SIL. Operational safety and cyber security use similar development processes. Here, the focus is on identifying and assessing the hazards and risks that can arise from the intended functions. Cyber security is a multi-dimensional concept that covers the entire technical life cycle and the entire organisation of a company. As regulation UN R155 is relevant to the type approval (homologation) of electric vehicles, it primarily concerns vehicle manufacturers. However, suppliers must also be able to demonstrate the cyber security of their products, internal processes and services.
Energy-less holding in position and switching tasks
Bistable brakes are responsible for holding devices in position with just a minimum amount of energy. As a “hand brake”, they prevent vehicles from moving unintentionally.
Bistable clutches enable the engaging and disengaging of movement axes or components. Through a one-off switching pulse (rather than continuous power), electrical energy is only required for the actual switching process. In “stable operating states”, bistable elements operate without consuming any energy which is a decisive advantage particularly for battery-powered systems.
Operating current-actuated brakes and clutches
Thanks to frictionally or positive connection the COMBINORM products are particularly suited for precise positioning and reliable holding.
Safe release function without residual torque and no maintenance throughout their entire service life complete the performance.
