Seasonal report wonderland Erzgebirge “Dresden ” is the name of the sec- ond limited edition of a mechanised arch from the Klaus Kolbe manufactory in Seiffen. It is populated by some 100 figures, and that not counting those which serve as tiny decorations on the market stalls and the Christmas pyramid. In the plinth of this jewel of wooden craft art, moving figures depict the inven­- t­ion of Meissen porcelain.

In this way, the VEMoDRIVE compact motor supports the efforts of fan manufacturers to improve energy efficiency. Furthermore, it places not just the motor and converter in the focus, but rather the whole system, including the driven machine. And thirdly, the VEM drive in a grey- cast housing comprising two main compo- nents and two add-on parts is designed for simple mounting and intelligent integration in diverse industrial environments.

Motors with axial converter are currently avail- able for the outputs 5 kW (2-pole) and 4 kW (4 pole). The first frame size will be launched as a series product from 2016. Further output classes and sizes are to follow in the future.

On the basis of the archived documentation of the original project, the local installation conditions were mapped onto a new VEMoDRIVE converter. The tricky challenge of adapting interfaces and connections to the new hardware and software was also mastered.

The project needed to be completed within five weeks after receipt of the order. But the team from VEM transresch in Berlin was still able to deliver on schedule – and that to the full satisfaction of the customer.
