Product Description:
The MSK071E-0300-NN-M2-UG2-RNNN belongs to the MSK IndraDyn S Synchronous Motors series produced by Bosch Rexroth Indramat. It is an IndraDyn S synchronous servomotor intended for closed-loop positioning and velocity control in industrial automation systems such as pick-and-place gantries, packaging axes, and CNC feed drives. With a motor size 071 frame and the E length variant, it offers an increased concentricity design that limits shaft runout, and its plain shaft simplifies coupling to gearboxes or belt pulleys without keyways.
Thermal behavior is managed through natural convection, so heat dissipates into surrounding air without additional fans, although the model is marked with a cooling FN requirement for system planning. The encoder connector can be positioned within a rotatable 240° window, facilitating cable routing in tight cabinets. Position feedback uses the digital EnDat2.1 interface; this optical system delivers 2048 signal periods per revolution and stores absolute position over multiple turns via a multiturn absolute mechanism, eliminating the need for homing after power-up. An electrically released holding brake supplies 30 Nm of static torque, securing vertical loads when the drive is de-energized.
The housing carries a protection rating of IP65, so internal components resist dust ingress and low-pressure water jets during washdown procedures. Continuous operation is specified within an ambient range of 0–40 °C, matching typical factory floor climates, and insulation class 155 allows winding temperatures up to 155 °C before thermal aging accelerates. Winding code 0300 indicates the electrical characteristics used with IndraDrive controllers, while the multiturn encoder, rotatable connector, and increased concentricity support precise interpolation and smooth rotation across the whole speed range.
