Product Description:

The MSK050B-0450-NN-S2-UG1-RNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As a compact rotary drive, it converts electrical energy from a servo amplifier into controlled torque and speed for pick-and-place gantries, tool spindles, and conveyor axes. The motor includes position feedback and an electrically released holding brake, allowing the axis to execute rapid motion and then remain secure at standstill without an external locking device. This combination supports precise rotary motion where compact installation space and repeatable stopping behavior are important.

The housing uses natural convection for cooling, so no forced-air or liquid circuit is required. Position data is transmitted through the EnDat2.1 interface from an optical encoder with 2048 signal periods, which supports stable feedback quality for speed and position control. The encoder connector can rotate 240 degrees, making cable routing easier when surrounding machine parts limit available space. An electrically released brake provides 6 Nm of holding torque to keep the shaft still after motion stops. The enclosure has an IP65 rating, which helps protect internal components from dust and low-pressure water jets during washdown exposure.

The motor uses winding code 0450 with a size 050 stator and a B-length frame, allowing it to fit compact mechanical layouts. Continuous operation is permitted within 0–40 °C, and Class 155 insulation supports elevated winding temperature without reducing basic thermal durability. The feedback system is single-turn, so absolute position is retained within one mechanical revolution and can be paired with external homing methods when needed. A plain shaft supports clamp-style couplings and avoids the stress concentration associated with a keyed output. The internal design also uses increased concentricity to reduce runout at the output flange, which helps maintain smooth rotation in accuracy-sensitive axes.
