Electric motors for mechanical and plumbing equipment. <br /> i <br /> ' i 1.2 SUBMITTALS <br /> I A. Submitals: <br /> il. Submittal data is not required for this section. Provide motors <br /> � which comply. <br /> ; PART2 -PRODUCTS <br /> � 2.1 EQUIPMENT <br /> � A. Electric motors shall be new, equipment manufacturer's standard, <br /> � NEMA Standard, sized and designed to operate at full load and full <br /> � speed continuously without causing noise,vibration, and <br /> � temperature rise in excess of their rating. <br /> ' <br /> B. Motors on belt driven equipment shall have slide rails with <br /> ; adjusting screws for belt tension adjustment. <br /> I C. Motors exposed to the weather shall be weather protected. <br /> I D. Motors shall be high efficiency type. <br /> ' E. Motors shall have efficiency and losses determined in accordance <br /> with the latest revisions of IEEE Standard 112. Polyphase squirrel- <br /> cage motors rated 1 through 125 horsepower shall be tested by <br /> idynamometer method B. The efficiency shall be determined using <br /> i segregated losses in which stray load loss is obtained from a linear <br /> � regression analysis to reduce the effect of random errors in the test <br /> measurements. <br /> F. Motor sound power levels shall not be greater than recommended <br /> in NEMA M61-12.49. <br /> G. Motors shall be provided with drive shafts which extend <br />� � � completely through belt sheaves. <br /> I � <br /> , � � <br /> ICT 9�9184 <br /> i i 15170 - 1 <br /> i <br /> i <br />� _ � � <br />
