Metadyne
A metadyne is a direct current electrical machine with two pairs of brushes. It can be used as an amplifier or rotary transformer. It is similar to a third brush dynamo but has additional regulator or ""variator"" windings. It is also similar to an amplidyne except that the latter has a compensating winding which fully counteracts the effect of the flux produced by the load current. The technical description is ""a cross-field direct current machine designed to utilize armature reaction"". A metadyne can convert a constant-voltage input into a constant-current, variable-voltage output.
