| (2) poles and an armature about ten inches in diameter by about 6, or whatever is necessary in length; - must be capable of absorbing the 50 h.p. at 1000 revs. or as an excessive overload 100 h.p. at 2000 revs. The efficiency need only be sufficiently good to keep the generator from overheating in the armature. If the armature is well ventilated, it can be made to carry a big load and the quotation may be sent in for different temperature rises up to 100 degs. centigrade with a five hours run. We should make our own bed-plates and other dynamometer arrangements; the only thing we should require would be circular fairly well-balanced field magnet system, with | ||
