Technology is with us in almost all areas of life. Automated systems not only make life

easier – they also make consumer goods widely affordable.

As a result, the next generation of specialized workers is going to have to work even

harder on the requirements associated with system automation. Trends such as energy

efficiency in automation technology are creating new challenges, but also opportunities for

the training of specialists.

Didactics – tailor-made and practical

The SEW‑EURODRIVE portfolio is based around the official German “Lernfeld” (learning arena or field) curriculum classifications and is geared toward typical lecture content. It has been developed for use in further education and training – for example at vocational schools or training centers in industry and at colleges and universities.

At SEW‑EURODRIVE, we have established seven key topic areas:

1. Gear unit technology2. Cut‑away functional models3. Electromechanics4. Application5. Systems6. Documentation7. Connection leads (cables)

The gear unit technology didactics models are ideal for all training associated with metal‑ working occupations such as mechatronics technician and industrial mechanic that falls under “Lernfeld 10”. Industry‑standard gear units have been specially modified for use in training. The modules can thus be used to replicate the simple assembly and disassembly of a wide range of gear unit parts, without the need for expensive pressing tools. The gear unit parts are protected against corrosion, making them wear‑free. The clear presentation of all components and tools ensures short preparation and follow‑up times.

The cut‑away functional models demonstrate how the components inside helical, helical‑bevel and helical‑worm gear units interact and how a gear unit works. Each cut‑away model has a nameplate showing the key data, thus also enabling calculations for features such as speeds and ratios. Our electromechanics didactics modules support practical operation of various electric motors. Safety is a top priority in the laboratory environment. All electrical signals connect to laboratory test sockets and

industrial plug connectors. Live components are covered, while power and control signals are separated from each other physically and visually. The freely available MOVITOOLS® and MOVISUITE® engineering software from SEW‑EURODRIVE offers an ideal training platform for practical and hands‑on tasks, with a particular focus on laboratories.

The topic area application covers typical applications. Lifting gear is one challenging example. Besides the configuration of the drives, the initial design concept also factors in special safety guidelines for subsequent operation. Various gearmotor combinations can be used, and either a centralized or decentralized concept can be selected for the control system and the power supply.

Our two didactics systems, starting with the multi‑ functional model, can be used to create various SEW‑ EURODRIVE components to customer‑specific require‑ments. The conveyor line has a modular structure, and the sensor technology and drive can be operated directly from the grid or by using a frequency inverter.

In addition to the electromechanics and gear unit tech‑nology modules for practical use, SEW‑EURODRIVE offers various documents/materials for teaching theory. The prefabricated connection leads (cables) ensure users can safely get straight on with connecting and running the electromechanics didactics modules. Various standard industrial plug connectors that are connected to 4‑mm shrouded plugs are available.

The leads are shielded, thus making them suitable for EMC‑compliant wiring. The connection leads can be combined and used with various didactics modules and lab benches.
