eWheel | size L

Our eWheel size L is our large motor for high performance and high vehicle speeds for your AGV application.

The motor of the drive system is equipped with IP54 and is a dynamic internal rotor with 4 pole pairs.

It also contains an encoder with 1024 increments and Hall sensors.

This means that our eWheel has a redundant encoder system and, by aligning both signals, the corresponding electronics can reliably detect the speed (SLS and SDI)

Furthermore, our eWheel L is also extremely overload-capable with a low moment of inertia.

Product options

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.

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.

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.

Please contact us for further information!

Functional safety

In normal operation, the eWheel’s BLDC motor brakes regeneratively and feeds energy back into the battery or to other consumers. For safety-related emergency braking, the eWheel has a mechanical holding brake with emergency stop function.

The braking torque is increased accordingly by the gearbox so that the vehicle comes to a safe standstill 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 system for SLS and SDI

Solution with SLS and SDI through safe encoder

Solution with SLS and SDI with Siemens MicroDrive-PDC
