[Milsurplus] Help with Bendix Dynamotor

[Scott Johnson]

Since a dynamotor, by definition, has a common field winding, you really 
can't adjust the output voltage with the field coil.  The result would be 
overheating of the armature, and very poor regulation. Normally, dynamotors 
are compound wound, with no control other than on/off.  If you have the 
dynamotor PN, I may have tech data on it.
