Stator And Rotor
|
According to ENERCON’s service life requirements the copper winding in the stator, the stationary part of the annular generator, known as closed, single-layer basket winding is produced in insulation class F (155°C). It consists of individual round wires that are gathered in bundles and varnish insulated. ENERCON does the copper winding by manually. In spite of increasing automation in other manufacturing areas, preference has been given to manual labour in this case for good reason. It ensures that the materials used are fully tested. Furthermore, a special processing method allows continuous windings to be produced. Each wire strand is continuous from start to finish.

Advantages of Continuous Winding
- Prevents processing faults in the production of electrical connections
- Maintains the high-quality copper wire insulating system
- No contact resistance
- No weak points susceptible to corrosion or material fatigue
|
The magnetic field of the stator winding is excited via pole shoes. These are located on the disk rotor, the mobile part of the ENERCON annular generator. Since the shape and position of the pole shoes have a decisive influence on the noise emission of the annular generator, ENERCON’s Research & Development Department has dedicated particular attention to this aspect. The result: Improved adaptation of the pole shoes to slow rotation of ENERCON’s annular generator means that no noise is generated.

Temperature Behavior
ENERCON’s annular generator features optimized temperature control. The hottest areas in the annular generator are constantly monitored by a large number of temperature sensors. The sensors activation temperature is well below constant temperature resistance of the insulating materials used in the generator. This prevents temperature overload.
