Designing a transformer itself is simple enough: traditional formulas, well known by any good electrical engineer and an Excel sheet are sufficient.
But difficult is to create a product that meets customer specifications at minimal cost and, even more difficult is to build a technical environment that encourages this process.
In a mature industry such as transformers, competitiveness is more and more a question of specialty : special products, non-standard, electrical and dimensional requirements often very strict.Prices and terms of delivery are definitely fundamental. To overcome the competition and increase the margin now the watchwords are:
- Research and development
The final cost of the product is decided during the design.
The engineering determines the characteristics, the shape of the product, the content of materials, the ease (or difficult) manufacture and finally the cost; time also affects the cost of the project - because it is spent by the most qualified personnel - and the reduction of design time is beneficial for productivity and delivery terms.
And 'here, then, one must focus.
- Calculation methods must work well also for special, non-standard, and smaller-sized products
- You have to be able to quickly produce several design versions in order to choose the best. That will allow you to optimize the product without wasting time.
- Retrieving similar projects must be easy, so you can use them as templates, thus saving time and money.
- Your design should be oriented toward the use of standard materials.
- It is very important to automatize the design of mechanical parts, as well as the production of the bill of materials and the manufacturing papers. This will reduce to a minimum the time spent on these phases.
- Your company’s know-how should be shared among your engineers through codified procedures.
