Abstract :
By action of the Board of Directors of the Institute at their meeting of February 10, 1927 the Standards for Induction Motors and Induction Machines in General, No. 9, were revised. The revision adopted covers the sections of the Standard dealing with rating and is the result of the continued efforts of the A. E. S. C. Sectional Committee on Rating of Electrical Machinery to obtain a decision satisfactory to all. Such unanimous approval has finally been obtained by the Rating Committee under Dr. D. C. Jackson´s chairmanship and the decision reached will now be applied to the revision of rating sections of Pamphlets 5 and 7 on “Direct-Current Generators and Motors” and “Alternating-Current Generators, etc.,” respectively.
