Our expertise, your solution

We have fully mastered each of our motor technologies. Consequently, we provide you with expert and targeted advice at all times. If you are not sure what drive is right for your application – we can tell you. Thanks to our many years of experience in all kinds of application areas and sectors, we know all the challenges that need to be mastered. We apply our knowledge for every special solution. For example, we have been doing this in the area of explosion protection for over three decades. And we have a wealth of experience in all kinds of applications – from wind power, shredder and recycling plants, extrusion, car and truck dynamometers to traction and lifting motors in all kinds of vehicles and factory truck technology. Don’t take chances. Let the qualified experts from EW HOF work for you.

Mechanical design and simulation

For mechanical design and simulation, we use state-of-the-art design and analysis software. We use a CAD system to create 2D and 3D designs (file support) and also carry out bearing calculations, strength simulations and oscillation analyses. Individual adjustment to the customer interface, for example by shaft geometries or flange models, is also an integral part of our tried-and-tested process.

Attachment and integration

We offer professional attachment of components, such as gearboxes and encoders. If you would like particular functions integrated into your product, we will implement these for you – from brakes and hollow shafts to sensor bearings. Our skill sets also include the integration of process forces.

Electrical calculation and simulation

We work with special analytical calculation programs for direct current and asynchronous machines as well as with numerical field calculation programs (FEM) for asynchronous and synchronous machines. Our range of services also includes computer-assisted heating simulation using network generation. If you need support with the drive design and dimensioning, we can help with that, too.

Control and testing

We have six test facilities for load tests up to 55,000 Nm. In addition, we use a water recooling system for motors and converters and can conduct test with up to 690 V supply voltage. Apart from a complete test with the customer’s converter systems, we also carry out oscillation and noise measurements. Would you like a complete acceptance test with independent experts, e.g. PTB, TÜV, GL, UL, CSA? We can help arrange these kinds of acceptance tests.

Mechanical production

We offer conventional mechanical production and CNC machining services for drilling, turning, milling, and grinding. In addition to steel and aluminium welding, we also braze copper squirrel cage windings and manufacture stator and rotor packs.

Electrical production

At EW HOF, we produce coils in round or flat wire design and rely on high quality insulation materials and vacuum impregnation. Depending on requirements, we can use manual or automatic coiling or bandaging in production.

Final assembly

If all other process steps have been carried out, the product moves on to cell or assembly line production. Here we can offer individual part handling of up to 8 tons as well as the complete assembly of attachment components.

Painting/coating

We have 2 state-of-the-art paint booths to implement standard or customised paint requirements – single or multi-layered. Do you need moisture, acid or tropical protection for your drive solution? EW HOF is the perfect place to look. What else can we offer you? Certified offshore paintwork (C5 M-H) – “Perfection that is more than skin deep!”
