A close relationship and quality are not just business axioms but a claim that has to be proved daily. Founded in 1910, Ziehl-Abegg unleashed another trend-setting breakthrough in the 1950´s when the external rotor motor was developed as a motor for fans. Since that time the principle has been optimised and transferred into many new applications.

Ziehl-Abegg, your partner around the globe!

Ziehl-Abegg has developed an outstanding image and became market leader in important areas, such as; elevator drive production, motor production, fans and control systems, all at a qualitively high standard.

Wherever there’s an elevator or escalator in motion, most times there’s a Ziehl-Abegg motor hidden in the background. Whilst the “made in Kuenzelsau” fans, (for applications such as air-conditioning large buildings) are in great demand, Ziehl-Abegg electronic control systems are also in great demand, because of their ability to efficiently speed control fans, highly desirable in applications such as clean room air-conditioning and refrigeration technology.

Ziehl-Abegg offers control systems for the drive market sector. They are held in high acclaim for position accuracy and passenger ride comfort, freight elevators, storage and retrieval drives, cranes and lifting machines. With 1500 employees in the Parent company in Kuenzelsau, the facilities in Bieringen and near Waldenburg, in the Hohenlohe trade area, Ziehl-Abegg ranks as one of the largest employers in Hohenlohe. 

Ziehl-Abegg have subsidiaries, production facilities, representations and business partners in more than 30 countries in the world, to ensure worldwide access to the electro-mechanical products that are made near to the Kocher and Jagst rivers. Our sales network, through which new markets are acquired permanently, stretches from Australia to Canada, from Scandinavia to South-Africa, from Great Britain to China.

TM4 supplies motors, generators and inverters for the two markets it serves:

• Transportation: customized electric drivetrains for electric and hybrid vehicle manufacturers.
• Power generation: generators for wind turbine and gen-set manufacturers.

Protean Electric is a leading clean technology company that designs, develops and manufactures Protean Drive™, the most advanced in-wheel electric drive system for hybrid and battery electric vehicles.

Our revolutionary Protean Drive™ in-wheel propulsion system and development platform is challenging the status quo by delivering practical ways to electrify full-size vehicles – with no compromises. Our game changing system and development platform gives engineers and integrators the power, space, flexibility and freedom they need to create the next generation of clean and efficient electric vehicles– without compromising power, fun or curb side appeal. Our system allows electrification of full size sedans, SUVs and pick-up trucks, and with our unique full-electric regenerative braking the well-to-wheel CO2 emissions of larger vehicles are similar to those of a small city car.

The revolutionary Protean Drive™ system is a powerful, light and clean power delivery system and development platform that meets a wide range of vehicle propulsion applications. It is a disruptive in-wheel vehicle propulsion system providing power to each wheel under the control of a central Electronic Control Unit (ECU) using advanced software control technology. The system is being developed to meet all required International standards for safety and reliability.

We are working closely with many major vehicle manufacturers around the world and our technology forms the basis of the Volvo ReCharge, one of the world’s first series-hybrid electric vehicles, and a fully electric Ford F150 pick-up truck.

The name indicates electric car components designed using know-how provided by SIM-Drive Corporation.
The car is comprised of a platform installed with a drive system consisting of an in-wheel motor, inverter, and battery.
These technologies can be utilized in modified existing new and used cars as well as “ground up” models (newly designed electric cars).
Cars installed with components certified by SIM-Drive will be labeled “by SIM-Drive” or “Platform by SIM-Drive”.

Compact system constructed by placing planetary reduction gears around the inner periphery of a flat motor

System with high installment flexibility is realized by eliminating the requirement of an external cooling system by using automatic transmission oil to both gear lubrication and motor cooling

Highly efficient system is achieved by optimizing a current of IPM motor using a vector control

The eCorner concept replaces the conventional wheel suspension with hydraulic shock absorbers, mechanical steering, hydraulic brakes and internal combustion engines with integrated in-wheel systems. Siemens VDO says that although it will naturally continue to invest in optimization of conventional internal combustion engines in an effort to completely exhaust their potential, its focus for the future is on these in-wheel systems.

Within eCorner, electric motors will take over the task of ensuring contact between wheel and road. With this new suspension, hydraulic steering can be eliminated, giving automakers new degrees of freedom. Each individual wheel will be able to be moved to its own specific steering angle.

Michelin’s Active Wheel technology has been around for the past couple of years but actual applications of the electronic powertrain and handling management system are still hard to come by

Mitsubishi Motors has chosen to center its development of next-generation electric vehicle technology on in-wheel motors, which minimize drivetrain space requirements, and on lithium-ion batteries with their superior specific energy characteristics. Dubbed the Mitsubishi In-wheel motor Electric Vehicle (MIEV) concept, the company is currently working on a test vehicle that utilizes these core technologies. The MIEV concept offers a very promising clean propulsion solution in this the century of the environment and the company also envisages its application to hybrid electric and fuel cell vehicles.

The four electric motors are located in the wheels - one inside each wheel. While they have consequences in terms of unsprung weight (that add lots of weight to each wheel) which will affect handling, everyday driving in the Volvo ReCharge Concept will be kind to both your purse and the planet, explains the Swedish car maker.

The PML eWheel range of permanent magnet wheel motors is designed to be rugged, flexible and adaptable to suit many applications. Based on 5 years of evolution, the eWheel offers exceptional efficiency, coupled with a high power to weight ratio that makes it the ideal solution for battery powered equipment.
