<br />10. Motors shall have inverter duty complying with NEMA MG-1 Part 31.40.4.2. <br /> <br />2.02 NAMEPLATE' <br /> <br />A. Provide stainless steel nameplate for each motor, attached to the motor by stainless <br />steel screws or drive pins. Nameplates shall indicate clearly the information <br />required by NEMA MG1, Part 10 and MG1-12.55. <br /> <br />2.03 ENCLOSURE TYPE 8Y LOCATION <br /> <br />A. Indoors. Vertical motors shall be drip-proof with guard. <br /> <br />2.04 INSULATION <br /> <br />A. Provide Class F Insulation with Class B temperature rise. <br /> <br />2.05 MOTOR HORSEPOWER <br /> <br />A. The maximum permissible motor loading: <br />1. Motors with service factor 1.15 or greater: 100% of nameplate horsepower. <br /> <br />8. Probable motor horsepower ratings have been specified in the Pump Schedule in <br />section VERTICAL TURBINE PUMPS. Changes from the specified horsepower <br />may be accepted, If necessary to assure that motors do not exceed their maximum <br />permissible loading, as defined above, under normal operation. Motor horsepowers <br />shall not be less than those specified In driven eqUipment sections. If a larger <br />horsepower rating Is required by the driven equipment, provide all changes required <br />to motor starting and control equipment and to the conduit and wiring system <br />without any additional cost to the Owner. <br /> <br />2.06 EFFICIENCY <br /> <br />A. Provide premium efficiency motors. Premium efficiency motors shall have nominal <br />efficiencies at full load not less than those listed In Table 1. <br />1. Guaranteed minimum efficiencies of premium efficiency motors shall <br />correspond to nominal values as tabulated in NEMA MG..1, Table 12-6. <br /> <br />8. Efficiencies shall be determined by using the IEEE 112, Test Method BusIng <br />segregated loss determination. <br /> <br />TABLE 1: MOTOR NOMJNAL EFFICIENCIES AT FULL LOAD <br />~\:':;}G;fEHRJ~~~~ ;J(r;:;::lQg~:fd:~Nt:::.::....: ....::.:1.,:2()Oj~P.NnyB .~~1[Q-Q:.B~,Mi.::.:.. !\,:::a,6oij':Rf.fM]j: <br />Open Drip-Proof and Weather Protected Type 1 Motor. <br />94.5 95.0 95.0 <br />95.0 95.8 95.8 <br /> <br />r~ <br /> <br />250 <br />300-500 <br /> <br />94.5 <br />94.5 <br /> <br />Shop Drawing Preparation Package <br />0988015.00 <br />C Kennedy/Jenks Consultants 2009 <br /> <br />Page 3 of4 <br /> <br />Electric Motor Drives <br />
