6.1 Designofthemotors

ThelinearservomotorsfromtheAL2xxxseriesarebrushlessthreephasemotorsforhighqualityservo

applications.Inconjunctionwithourdigitalservodrivestheyareparticularlysuitableforpositioningtasksin

industrialrobots,machinetools,transferlines,handlingequipment,textilemachines,packagingmachines,

etc.withhighrequirementsfordynamicsandstability.ThemotorsfromtheAL2xxxseriesareintendedtobe

operatedexclusivelybythedigitalservodrivewithspeedandtorquecontrol.

Thelinearservomotorsareequippedwithpermanentmagnetsinthemagneticplate.Thisadvanced

neodymiummagneticmaterialmakesasignificantcontributiontothemotors'exceptionaldynamic

properties.Athreephasecoilsuppliedbytheservodriveishousedinthecoilunit.Themotorhasno

brushes;thecommutationbeingimplementedelectronicallyintheservodrive.

Furthermore,afeedbacksystemisnecessaryforoperation.Thesuitablefeedbacksystemmustbeselected

onthebasisoftheapplicationrequirements.Dynamics,speed,contaminationlevels,resolutionandthe

servodriveemployedmustbeconsidered(seealsothesectionentitledMagnetic Encoder System ﴾MES﴿
