Highly ef­fi­cient and hy­gienic

DEMM Engineering & Manufacturing - - PRODUCT WATCH -

NORD Drivesys­tems has ex­panded its range of high- ef­fi­ciency smooth- sur­face mo­tors.

The new per­ma­nent-mag­net syn­chro­nous mo­tors without cool­ing fins achieve level IE4 / su­per pre­mium ef­fi­ciency. This can greatly ben­e­fit the food, bev­er­age, and phar­ma­ceu­ti­cal in­dus­tries, and other hy­gien­i­cally de­mand­ing ap­pli­ca­tions. The ef­fi­cient smooth-sur­face mo­tors are suit­able for use in dry ar­eas as well as in ap­pli­ca­tions re­quir­ing fre­quent clean­ing. As they gen­er­ate very lit­tle ex­cess heat, they need no fans and there­fore do not con­trib­ute to the spread­ing of germs.

The IE4 or Su­per Pre­mium Ef­fi­ciency syn­chro­nous mo­tors op­er­ate sig­nif­i­cantly more ef­fi­ciently than in­duc­tion mo­tors, specif­i­cally in the par­tial load range. This re­sults in sub­stan­tially lower cost for en­ergy con­sump­tion and lower TCO. The mo­tors fur­ther­more fea­ture a par­tic­u­larly high-power den­sity and a very long prod­uct life. Fre­quency in­vert­ers can be mounted di­rectly onto the mo­tor or near the mo­tor for per­fect flex­i­bil­ity.

Three mo­tor sizes (80, 90, 100) with power rat­ings from 0.75 to 2.2 kW are avail­able. They com­ple­ment the ex­ist­ing smooth­sur­face in­duc­tion mo­tor range, which al­ready cov­ers out­puts from 0.37 to 1.1 kW. The mo­tors can be sup­plied with a brake.

For wash-down-en­abled in­vert­er­con­trolled drive sys­tems with an IP66/ IP69K pro­tec­tion rat­ing, NORD can draw on four dif­fer­ent suit­able gear­box se­ries. Wash-down drive con­fig­u­ra­tions all fea­ture die-cast alu­minium hous­ings with smooth sur­faces, de­signed so that clean­ing flu­ids and foams eas­ily run off. For ex­tra cor­ro­sion pro­tec­tion, they can be fit­ted with the nsd tupH Sealed Sur­face Con­ver­sion Sys­tem, which is ap­proved for food and drink ap­pli­ca­tions in ac­cor­dance with FDA Ti­tle 21 CFR 175.300.
