Insulation Strategies in Converter Driven Machines,n life times. If the insulation system is not adjusted to the converter, damages will occur, see [8.12-8.16]. A proper winding insulation can be only designed, if the physical voltage phenomena in case of converter supplied drives are well known. Electrical motors must be protected in three main areas against electrical stresses.

Converter Applications in Typical Examples of Energy Efficient Pump Systems and in Processes with a are optimized taking the market liberalization and the strong contribution of renewable sources into account. Uncertainties in the power supply in grids with a large renewable wind energy component will request an adequate amount of power plants, which act as reserve.

Introduction,can be split in the following main areas: Energy, steel and metal, paper, oil and gas, chemical, mining, food and transport. The individual manufacturing processes cause special speed and performance requirements for the drives. A wide variety of converter-machine solutions is needed to cope with these requirements.

Conclusion,are often used for pumps and compressor loads or applications with special overload requirements and control quality. The special voltage waveform and the variable frequency impose special design measures on large electrical machines. Large electrical machines implement different constraints on converter applications than smaller machines.
