Abstract
Abstract A support device for a field winding of a field spider includes first and second support members which bear at least partially against free coil surfaces of adjacent field coils. The first and second support members mutually support one another against the field coils with various devices provided to urge the first and second support members apart. The support members may either be angled or flat with the flat support members crossing one another.
