X.294. - SHUNT WOUND DYNAMOS & VIBRATOR REGULATORS in particular X.1402 X 3560 X 3963 4162 X.3231. - SAMPLE 12 VOLT BIJUR GENERATOR WITH COMBINED CUTOUT & VIBRATOR REGULATOR SENT FROM AMERICA FOR TRIAL. As previously stated, we are carrying out a series of investigations on the design and performance of small shunt wound chassis lighting dynamos, both as plain shunt wound machines and in operation with vibrator regulator control. We are not yet in a position to issue any of the curves obtained in this connection, but we can make a few preliminary remarks. We are gathering together all particulars of - A.{Mr Adams} Component weights. B. Magnetic circuit. C. Field circuit. D.{John DeLooze - Company Secretary} Armature circuit. E.{Mr Elliott - Chief Engineer} Commutator & brushes. and making these out in the form of a large table. F.{Mr Friese} At the same time, in the matter of performance as a plain shunt wound machine, we are taking - (a) Open circuit volt-speed curves from 10 to 17 volts (cold). (b) Ampere output speed curve (cold) when operating upon an ideal standard battery with definite volt ampere relation. (see note). (c) Volt speed curve from 10 to 17 volts (hot). (d) Ampere output speed curve (hot) again operating on ideal battery. R.R. 199 (2501)(SD6/6 19-17) MPI80865 Contd. | ||
