Modelling is an important part of the development work. “That was already a major topic while I was still a student,” says Döring: “mapping and simulating technical systems and transfer functions as models.” When designing a motor, Döring needs three to four weeks of concentrated work in front of his screen to take the design from initial concept to final mapping. “Mapping motor characteristics, simulating cycles – without powerful computer workstations I can’t imagine how we’d do our work,” he says. Older colleagues have told him how, in the days before widespread computer use, they had to rely on gut instinct and years of experience, all carefully recorded and archived in countless ring binders.
Once the modelling phase has been completed, it’s time for the Design/Engineering specialists to get involved. In total, from receipt of order to finished prototype, it takes at least nine months to develop a new electric motor. Eleven specialists work in the team, most of them the same age as Döring. They all get excited when the prototype motor finally makes it onto the test bench and they start measuring its performance figures. Will it deliver what the customer wants? As a rule, yes, says Döring with the pride of a true engineer: “It’s very rare for test-bench results to deviate from our simulations.”
