Product Description:
The MSK050B-0600-NN-M2-UP1-RNNN is a servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servomotor, it converts drive-supplied electrical energy into precisely regulated rotary motion for positioning and cyclic tasks in automated machinery. The unit follows motor size 050 with length code B, giving it a compact profile for axes that need accurate torque delivery and integrated feedback control. It can be paired with a compatible drive for speed regulation, indexing tasks, and repeatable point-to-point moves in compact automation cells.
Cooling is handled by natural convection, so heat leaves the housing without fans or liquid circuits and the installation remains mechanically simple. The motor housing attains IP65 protection, blocking dust ingress and low-pressure water jets, while position data travel through the EnDat 2.1 digital interface and the optical encoder supplies 2048 signal periods per revolution for closed-loop operation. An electrically released brake provides 6 Nm of static torque for load holding during power-off conditions, and the increased concentricity design helps reduce runout during rotation. These features make the motor suitable for medium-torque feed axes, Cartesian gantries, and compact packaging equipment that use sealed housings and fanless cooling.
The encoder connector is rotatable through 240°, allowing the cable exit to align with surrounding hardware and reducing strain during installation. The encoder also provides multiturn absolute feedback, so the control system retains position information across multiple revolutions and does not require a homing move after shutdown. The winding code 0600 is matched to IndraDrive controllers, and class 155 insulation supports continuous winding temperatures consistent with F-class operation. Reliable performance is specified for ambient air from 0 to 40 °C, which supports stable operation in standard industrial environments. The connector arrangement also helps when cable routing space is limited near gearboxes, slides, or machine guards.
