Electric MotorsMiniature brushlessDC motor rangeRotalink has introduced new miniaturebrushless motors for nominal output torquesto over 250mNm at maximum efficiency andmaximum power ratings to 270WThe new BL brushlessmotors are verycompetitively priced andtogether with Rotalink'sown innovative and uniquelydesigned precision gearboxes,motor feedback devices andmotion controls, offer excellentprice vs. performance for completeminiature power transmissionsolutions. The BL motor range isavailable in both 12 and 24 VDCversions, complete with threephase hall effect commutation forsmooth and precise speed and/orposition control.The highly efficient brushlessdesign has an inherently lowelectrical noise factor and unlikebrushed DC motors is not prone tocommutation sparking; so themotor is ideally suited to EMCsensitive and safe environmentuse. In addition, the noncontacting characteristics will suitapplications where long life andhigh reliability are of primeconcern.The BL range includes fiveframe sizes with nominaldiameters of 29mm, 32mm,45mm, 57mm and 65mm.www.rotalink.comToughened highperformancemotor rangeMaxon Motor hasexpanded its range ofmotors for toughworking environments, byreleasing industrial versions of itspopular RE 50 and RE 65 units,along with a new AB 44permanent magnet brake.With outputs rated at 200Wand 250W respectively, the twobrushed DC motors have beenupgraded to meet the challengingIP54 protection rating for dirt andsplash proofing.Each one boasts a sealedaluminium housing and PG cablefittings, while the shaft is securedwith a radial seal. Between them,the motors offer operating speedsof up to 9,500rpm.www.maxonmotor.co.ukMclennan’s range growswith Allied Motion linesThe long-standing distributionpartnership betweenMclennan Servo Suppliesand Allied Motion has beenextended with the Surrey basedmechatronics specialist increasingits product line coverage ofAllied’s direct-drive torque motors,brushless servo motors, highperformance servo drives andencoders.Mclennan’s close relationshipwith the Allied Motion groupspans more than 30 years withmany thousands of successfulsmall and precision brushed andbrushless motor applications forPremotec – now one of four AlliedMotion engineering/productioncompanies or Technology Units.The new partnership aims tobuild a similar success with AlliedMotion’s Emoteq/COPI TechnologyUnit and will work across all of itsproducts which include framelessand housed torque motors, servomotors, digital servo amplifiers,and incremental encoders.Highlights of the new productsinclude the Megaflux range – largeframeless and separate rotor/statorservo motors, up to 790mm indiameter with with power densityand high speed.www.mclennan.co.ukNew guides and brochuresMicro motors, actuators and moreHIGHLIGHTThis month’sfeaturedliteratureHot off the press from EMS is a fulloverview of its product range.
