Abstract :
Pamphlet No. 9, A. I. E. E. STANDARDS for Induction Motors and Induction Machines in General has just been issued in revised form. The revisions included in this new edition concern the parts of the Standard dealing with rating, particularly rating of general purpose motors, and are the results of the work of the Sectional Committee on Rating of Electrical Machinery. This Committee under the chairmanship of Dr. D. C. Jackson has been at work for some time on the question of rating and the decision arrived at, which the unanimous vote of the committee shows is satisfactory to all, will now be applied also to Standards 5 and 7, “Direct-Current Rotating Machines, Generators and Motors” and “Alternators, Synchronous Motors and Synchronous Machines in General” respectively. Copies of the revised Pamphlet No. 9, June 1927, can be obtained by writing A. I. E. E. Headquarters, 33 West 39th St., New York, N. Y. Cost 40 cents to non-members of A. I. E. E.
