Parker servo motors were designed tomeet the requirements for variable speed drives.SMH synchronous servo motorsAn outstanding characteristic of SMH synchronous servomotors is their low rotormoment of inertia. Typical areas of usage for these motors are for packingmachines or automatic pressing and assembly machines for which rapidaccelerations and delays are required.SMH servo motors have smooth surfaces as well as depressions in the mountingareas that make it very easy to mount them on the gearbox.3 design sizes in 5 different flange sizes with edge lengths 60, 70, 82 and 100 mmand with 6 different shaft diameters are available in a output range from 1.4 to 6Nm (Over-temperature 65K).MH synchronous servo motorsMH series servo motors stand out due to their wide output range as well as amultitude of available options. Stall torques of the MH motor series cover a rangeof 0.2 to 90 Nm (Over-temperature 65K). 5 design sizes are available in 7 flangesizes with 56, 70, 96, 105, 116, 145 and 205 mm. The motors can be equippedwith different moments of inertia, which facilitates the adaptation to differentapplications. Active and passive ventilator fans complement a variety of options.Typical areas of application for these motors are therefore tool and printingmachines as well as handling robots.Both series, SMH as well as MH may, if desired, equipped with a holding brake. Asan alternative to the Resolver feedback, SinCos© single turn or a SinCos©Multiturn absolute value encoder are available.Together with the compact COMPAX servo control system and the intelligentCompax3 servo drive, these motors form a drive concept for use on powernetworks from 230 V to 400 V (460 V) AC.A wide range of gearboxes is available for all types of motors. The gearboxes canbe mounted if necessary.
