Siemens is expanding its global manufacturing network for wind turbine plants and is building a new production facility in Lingang New City in Shanghai. By establishing this new rotor blade and nacelle plant, the company is further strengthening its environmental portfolio. This new facility is scheduled to take up operation in the second half of 2010, initially with 400 employees. The wind turbine plants produced in Shanghai will be for the Chinese market and for export.
The stator, which forms the inner core of the motor, consists of around two
kilometres of wound copper wire. Unlike other electric motors in the same power
class, the motor of the BMW i3 is very small and compact due to the specially
configured winding of the copper wiring. This results in further weight and
space savings. Before the rotor is fitted in the interior housing, it receives a
thin coating of resin.
