82/131 Bosch Rexroth AG | Electric Drivesand ControlsRexroth MKE Synchronous Motors | Project Planning ManualOperating Conditions and Application NotesThe first characteristic numeral defines the degree of protection against contactand penetration of foreign particles. The second code numeral defines the degreeof protection against water.1st code numberDegree of protection6 Protection against penetration of dust (dust-proof);complete contact protection2nd code numberDegree of protection5 Protection against a water jet from a nozzle directed against thehousing from all directions (jet water)Fig.9-9:IP degrees of protectionThe inspections for the second ID number are executed with fresh water.If cleaning is effected using high pressure and/or solvents, coolants, or penetratingoils, it might be necessary to select a higher degree of protection.The design of the MKE motors complies with the following Degrees of protectionaccording to DIN VDE 0470, Part 1, ed. 11/1992 (EN 60529):Motor areaMotor housing, output shaft, power andencoder connections (only if mountedproperly)Degree of protectionIP 65CommentStandard designFig.9-10:IP degree of protection for the motors9.4 Compatibility9.5 Designs and Installation PositionsAll Rexroth controls and drives are developed and tested according to the stateof the art. However, since it is impossible to follow the continuing further developmentof every material with which our controls and drives could come intocontact (e.g. lubricants on tool machines), reactions with the materials that weuse cannot be ruled out in every case. For this reason, you must execute acompatibility test between new lubricants, cleansers, etc. and our housings anddevice materials before using these products.MKE motors are available in design B05. Please refer to the table below for theconditions of installation permissible according to EN 60034-7:1993.

If motors are attached according to IM V3, fluidpresent at the output shaft over a prolonged time may penetrate andcause damage to the motors.⇒ For that reason, make sure that fluid cannot develop at the output shaft.9.6 Housing VarnishThe housing varnish of the motors consists of a black (RAL9005) 2K epoxyresin coating based on epoxy polyamide resin in water.Chemically resistantagainstLimited resistance againstNo resistance against●●diluted acids and alkalinesolutionswater, sea-water,sewage●●organic solventshydraulic oil●concentrated acids/brines●current mineral oilsFig.9-12:Varnish resistanceIt is permitted to provide the housing with additional varnish (coat thickness nomore than 40 µm). Check the adhesion and resistance of the new varnish coatbefore applying it.9.7 VibrationSinusoidal vibrationsSine-shaped vibrations occur in stationary use; depending on their intensity,they have different effects on the robustness of the motors.Based on DIN EN 60721-3-3 and DIN EN 60068-2-6, the following values resultfor Rexroth motors:
