Electrical systems transfer electricity which is mostly produced and consumed by rotating electrical machines. Further, the use of electric and hybrid electric drivelines in both passenger and heavy vehicles is now commonplace and with a continuously growing market share. At the same time, increased computational power and novel control algorithms enable opportunities to reduce energy consumption and/or improving various performance metrics of electric drives. Electrical machines and electric drives are therefore a vital part of the future electrical ecosystem in the global quest towards solutions to environmental challenges.The activities encompass design and analysis of novel electric machinery and electric drives for traction applications as well as corresponding auxiliaries. In recent years, focus has been put on modular converter and machine concepts in order to realize compact integrated electric drives. Further, design of electric machinery taking production aspects into account and the interaction between battery systems and power electronic loads are presently being investigated.

Underground metal detector using voice alarm and instrument, according to the detection depth to be ground area, shape, weight of the metal has a lot to do, in general, the area is larger, the more the number, the corresponding detecting depth is larger; Conversely, the smaller the area, the smaller the number and the smaller the corresponding depth. The maximum detection depth listed in the following table is embedded in the dry soil by a 60cm * 60cm * 0.5cm (0.5cm) aluminium sheet in accordance with the product's enterprise standard
