Bosch Rexroth IndraDyn S - MKE Project Planning Manual

8/131 Bosch Rexroth AG | Electric Drivesand ControlsRexroth MKE Synchronous Motors | Project Planning ManualIntroduction to the ProductStructure and components●●●●●High performance dataHigh dynamics (owing to the favorable ratio of torque to inertia mass)High overload capability (owing to the favorable heat dissipation from thestator windings to the outside wall of the motor housing)Peak torque utilizable across a wide speed range (owing to electroniccommutation)Continuous start-stop operation possible with high repeat frequencies(owing to electrical commutation)● Easy attachment to the machine (owing to flange according to DIN 42948)11.65)●●Any installation positionSimple and fast startup (thanks to data memory)MKE motors are permanent-magnet motors with electronic commutation. Specialmagnet materials permit the motors to be designed with low inertia masses.The following figure shows the principal design of MKD motors.1.1.2 Versions(1) Drive shaft(2) Stator with winding(3) Bearings(4) Motor encoder(5) Connection unit(6) Terminal box lid(7) Holding brake (optional)(8) Grounding clamp(9) Shaft sealing ring(10) Rotor with permanent magnetsFig.1-2: Design of MKE motorsMHE motors are available in various designs. On the basis of existing nationalregulations and standards, the MKE motors have to be subdivided into housingtypes●●.E according to European Standard (EU) andU according to American Standard (UL)
