100 [[underline in red]] COPY [[/underline in red]] REID ICE CREAM CO. NY-34404 Schenectady, Nov. 4, 1925. Mr. D. W. Mc Lenegan, Building #2. This letter is to confirm our telephone conversation of this morning, regarding the torques of the motors on the above proposition. Referring to MC-127042, you have informed me that Item #1, as originally designed, is satisfactory with regard to torque requirements. However, Item #2, #3, and #4, because of the necessity of two (2) ballast rings each to meet a ratio of WR2 to Po of 117 or more, require a minimum starting torque of 50%, while 30% pull-in torque will be sufficient. In order to meet this requirement on Item #2, without affecting Po, I have found it necessary to alter the armature winding in accordance with MC-127042-2-A. With this change, and the omission of the steel bars from the double squirrel cage winding, the starting torque has a value of 49%, and the starting current 214%. By increasing the discharge resistor to 20 times the field resistance, the torque requirement should be met. On Item #3, the only change necessary is the omission of the steel bars in the double squirrel cage winding. The torques should then be approximately 53% on starting, and 47% on pull-in with a starting current of 230%. On Item #4 also, the only change necessary, is the omission of the steel bars in the squirrel cage winding, which should result in torques of approximately 55% on starting, and 50% On pull-in, with a starting current of 250%. By copy of this letter, Mr. Treene will note the various changes to be made in order to meet your requirements. H. G. REIST BY: F. H CRATON A. C. ENGR. DEPT. FHC: MR W. H. TREENE
