In many industrial applications there is a growing demand for powerful electric motors, even though the available installation space is limited, especially in the axial direction. At the same time, drives, as the heart of mechatronic systems, must meet high requirements in terms of dynamics, efficiency and integration.
This challenge has often been solved by radial flux-based motor concepts based on stacked laminated core geometries. Customer-specific adaptations for small to medium quantities are often only possible to a limited extent. Typically, this involves varying the overall length and adapting the winding design. In addition, there are sometimes high tooling costs, for example for punching tools, which make it difficult to achieve cost-effective individual geometries.
The electric motor industry in transition
The electric motor industry combines a long engineering tradition with strong pressure to innovate due to electrification and automation. The market landscape ranges from specialised manufacturers of special motors to volume-driven corporations with very high production volumes. At the same time, developers benefit from a mature supply industry and a high degree of standardisation in peripheral components such as sensors, connectors and cooling systems, which accelerates integration into overall systems.
Axial flow motors as an alternative for compact system designs
Axial flow motors from WEBER-HYDRAULIK are characterised by a particularly compact, disc-shaped geometry. Compared to classic radial flow motors, they can be integrated in a space-saving manner when the axial installation length is critical. This gives designers additional freedom in system integration, for example when the motor, mechanics and electronics need to be brought closer together.
Advantages of WEBER-HYDRAULIK axial flow motors are:
• Space-saving integration thanks to very compact design for short installation spaces
• High torque density thanks to optimised magnetic flux guidance
• Flexible installation options in different drive systems
• Technologically advanced alternative to conventional radial flow motors
• Cost-effectiveness for customer-specific designs due to reduced tooling costs
• Integration of motor, electronics and pump in a single unit
WEBER-HYDRAULIK is pursuing an approach for electric hydraulic and pump units that reduces the classic separation of components. The goal is a highly integrated solution in which the motor, power electronics, and pump unit can be combined in a single structure. This reduces volume and weight while also reducing cabling and interface costs.
Another special feature is an ironless rotor, which reduces inertia. This supports high operating dynamics during speed changes, for example, in pump applications or dynamic control loops.
Plug-and-play installation and tested pre-assembly
A plug-and-play assembly concept is provided to simplify integration into the customer’s application. The unit is supplied as a tested pre-assembly module. The approach aims to simplify final assembly in customer production, reduce process costs, and minimise potential sources of error by using fewer individual components. End-of-line tests support standardised quality assurance prior to integration.

“Axial flow motors enable compact drive solutions when installation space and system integration are crucial. The customer-specific design and integration concept allow development and assembly costs in electrohydraulic applications to be reduced in a targeted manner,” says Dietmar Andessner, head of axial flow motor development at WEBER-HYDRAULIK.
