b-drives® eWheel - Wheel Drive for Automated Guided Vehicles (AGVs)
With the eWheel from b-drives, your transport systems bring even large payloads safely to their destination in the tightest of spaces.
The eWheel is the most compact system on the market for this purpose and can be easily adapted to your design ideas thanks to its flexible modular system. But that’s not all: Despite its small size, the eWheel impresses with a very high power density and high efficiency.
This results in high vehicle availability. The b-drives mounting concept ensures optimum wheel changes. By loosening just three bolts, the wheel can be changed in just a few seconds. Behind the transmission-wheel unit, a modern BLDC motor with a redundant encoder system ensures safe drive.
The overload capability makes a positive impact during vehicle acceleration and overcoming inclines.
Best of all, our innovative wheel drive is the cost benchmark for AGV drive systems.

Additional options
Wheel covering
Our standard wheel covering is Vulkollan® 92° Shore A, but other wheel coverings of Vulkollan® 70° Shore A or other crowns are also conceivable and possible. Vulkollan® is a polyurethane traded by Covestro AG. Other materials and Shore hardnesses proven in intralogistics are also possible.
Please contact us and we will check your requirements for the wheel covering.
Sprechen Sie uns gerne an und wir prüfen Ihre Anforderungen an den Radbelag.

Mounting flange
We offer with our eWheel the possibility that you can mount it either from the outside or from the inside of the vehicle itself. This type of mounting is always given and is part of our standard program.
Only you have to choose in advance whether you want to mount the eWheel from the outside or from the inside. On this basis, we then select the appropriate mounting flange in production.
In addition, we can also offer you a standardized mounting bracket for our eWheel on request, in order to conveniently mount our eWheel under your vehicle chassis. This way you can easily screw the AGV above our eWheel.

Drive controller
Our dual-axis controller has STO (Safe Torque Off) according to PL e and can therefore be a component of your functional safety concept for your AGV. This is voltage resistant up to 60V at a peak current of 60A. In standard with CANopen interface. You therefore require a dual-axis controller for two eWheel per axis.
For more information, please contact us!

Functional safety
In normal operation, the eWheel’s BLDC motor brakes generatively, feeding energy back into the battery or to other consumers. For safety-oriented emergency braking, the eWheel has a mechanical holding brake with emergency stop function.
The transmission amplifies the braking torque accordingly so that the vehicle comes to a safe stop even in unfavorable operating situations. We can adapt the nominal braking torque to your application. For functional safety on the electronic side, the eWheel offers the following options:
Solution with STO
Redundant encoder systemfor SLS and SDI
Solution with SLS and SDI through safe encoder
Solution with SLS and SDI with Siemens MicroDrive-PDC
