eWheel – Overview
The eWheel from b-drives transports large loads safely and autonomously in confined spaces. As the most compact wheel drive system on the market, it easily adapts to your design requirements. Despite its compact size, eWheel offers impressive power density and high efficiency, which maximizes vehicle availability.
Our assembly concept enables quick wheel changes – loosening three screws is all that is needed to change the wheel in seconds. A modern BLDC motor with redundant encoders ensures a reliable drive, and the overload capacity is evident during acceleration and on inclines.
And the best thing is: our innovative wheel drive system sets a cost benchmark for AGV drive systems.
Maximum speed
Reaches speeds of up to 3.0 m/s and thus ensures efficient material movement in production.
Wheel covering
Available with Vulkollan® wheel tread for optimum adhesion and durability in demanding applications.
Drive power
Powerful BLDC motor with redundant encoder equipment for high overload capacity and safe drive control.
Product options
Our eWheel offers you complete flexibility. In addition to the gearbox and motor, the following options can be varied.
Wheel covering
Our standard wheel covering is made of Vulkollan® with a hardness of 92° Shore A. However, wheel coverings made of Vulkollan® 70° Shore A or other crowns are also conceivable and possible. Vulkollan® is a polyurethane traded by the company Covestro AG. Other materials and Shore hardnesses proven in intralogistics are also possible.
Drive controller
Our double-axis controller has STO (Safe Torque Off) in accordance with PL e and can therefore be a component of your functional safety concept for your AGV. The controller is voltage-resistant up to 60V with a peak current of 60A. Our standard interface for the double-axis controller is CANopen. You therefore need one dual-axis controller for two eWheels per AGV.
Assembly flange
With our eWheel, we offer you the option of either mounting it yourself from the outside or from the inside of the vehicle.
This type of mounting is always provided and is part of our standard program.
You choose the mounting direction, whether you want to screw the eWheel on from the outside or the inside. On this basis, we then select the appropriate mounting flange during production.
In addition to our eWheel, we can also offer you a standardized mounting bracket to attach our eWheel conveniently under your vehicle chassis. This allows you to simply screw the AGV/AGV above our eWheel.
We can also support you with your individual requirements when it comes to functional safety.
