There is a series winding on the vibrator regulator leg also the main field current is made to pass round another coil on this leg in an additive direction. We found the actual behaviour of the regulator contacts for this to be very good, but owing to the limited speed range during which the control is in action, and to the fact that the regulation due to the particular arrangement of windings is not what we consider to be that required for the purpose, we do not consider this regulator as being entirely satisfactory. We are strongly of the opinion that a regulator can be designed on sound mechanical lines embodying all the best points of the various regulators we know, which can be determined by experiment, which would give us a regulator with very satisfactory results under all conditions of working. We think by this means we could escape from the difficulties we are up against with regard to battery troubles of over-charging and undercharging, and also in connection with fusing, to which there is no satisfactory solution with armature reaction controlled dynamos. The risk of burning out lamps when the dynamo is disconnected would be greatly simplified, also the battery makers would welcome Contd. | ||
