Field coil core arrangement, has field coil core made of plastic or other non-conducting light or very light materials, where materials of core are selected to be suitable for better performance of operation and selected usage application

摘要

The arrangement has a field coil core made of plastic or other non-conducting light or very light materials. The field coil core has walls (1) made of a non-conducting light material (2) with a magnetic material (3). An inner chamber of the field coil core is made of another non-conducting light material (4) filled with another magnetic material (5). The materials of the field coil core are selected to be suitable for better performance of the operation of the arrangement and selected usage application.
