Product Description:
The MSK050B-0600-NN-S2-UG1-RNNN is a synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop positioning and velocity control in industrial automation, where compact rotary axes require high accuracy and low maintenance. The motor combines feedback, power transmission, and a holding brake in one housing, which helps reduce external components around the axis. This layout supports direct connection to IndraDrive amplifiers in compact handling and packaging equipment.
Cooling is handled by natural convection, so heat leaves the housing through ambient airflow without auxiliary fans. The enclosure is rated IP65, which protects internal parts against dust and low-pressure water jets on open machine frames. Digital position data is transmitted over an EnDat2.1 interface, and the encoder provides 2048 signal periods per revolution for precise commutation and position control. An electrically released holding brake supplies 6 Nm of static torque, which helps secure vertical or indexing loads when power is removed.
For mechanical alignment, the rotor uses an increased concentricity design, and the plain shaft works with standard clamp couplings. A rotatable 240° angled feedback connector helps with cable routing in tight spaces. The encoder uses an optical sensing method with a single-turn data format, so it reports absolute position within one mechanical revolution. Rated operation is permitted in ambient temperatures from 0 to 40 °C, and insulation class 155 supports winding temperatures up to 155 °C during overload peaks. Size 050, length code B, and winding code 0600 correspond to the magnetic stack and electrical winding arrangement used with 230 V class IndraDrive units while keeping inertia low for rapid cycle tasks.
