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.
