Correction in revision of induction motor standards

On page 297 of the A. I. E. E. JOURNAL for March there was given a table on “Limiting Temperature Rises for General Purpose Open-Type Induction Motors,” this table to be Table II in the revision of Section No. 9 of the A. I. E. E. Standards for Induction Motors and Induction Machines in General. In the third item of the table the temperature rise for collector rings and commutators was erroneously given as 35 deg. cent. It should have been 55 deg. cent.
