| x 4383 17.8.23. GOSHAWK OUTPUT CURVES REQUIRED TOGETHER ON ONE SHEET FOR COMPARISON. X.4383. X.294. X.9660. STANDARD DYNAMO OUTPUT CURVES:- (1) The curve represented by the figures contained in the general specification of electrical performance of the dynamo. (2) The output curve of the dynamo at 85ºC with the control brush set in such a position as just (only) to satisfy the specification of production test. (3) The output curve of the dynamo with the control brush so set according to instructions contained in the general specification of test. This may be approximately equivalent to taking the output curve at 70 to 75ºC. EFC. {E. Fowler Clarke - Electrical Engineer} | ||
