The R911330939 (MSK050C-0600-NN-S1-UG0-NSNN) is a Bosch Rexroth IndraDyn S synchronous servo motor featuring a size 050 and C-length frame. Designed in compliance with EN 60079 standards, it employs a natural convection cooling method and standard smooth shaft geometry, providing IP65 ingress protection. Integrated is a single-turn optical encoder with Hiperface interface, 128 signal periods, and a rotatable connector. The motor operates without a holding brake, delivers 6.8 A continuous current and 5.5 Nm continuous torque at standstill (100 K), with a maximum current of 24.8 A and maximum torque of 15.0 Nm. Winding inductivity is rated at 11,100 mH. The unit weighs 5.4 kg and functions in ambient temperatures from 0 to 40°C.

Frequently Asked Questions

What does the “S1” length code indicate physically?

The “S1” designates a shorter motor length than the “C” version, reducing axial footprint. The compact design aids integration into space-constrained machine axes.

How does the motor’s flange shape aid mounting compatibility?

The motor uses a standard square flange with four tapped holes for rigid mounting. The geometry ensures easy alignment with machine frames and coupling interfaces.

What shaft end features belong to the S1 variant?

The motor shaft includes a keyway and a flat in standard form for torque transfer. The design supports conventional couplings and backlash-controlled joints.

How does the motor housing profile support thermal management?

The housing has fins and a ribbed exterior to increase surface area. The profile enhances natural convection cooling and dissipates waste heat effectively.

Why does the housing use a cylindrical body over block shapes?

A cylindrical housing allows uniform temperature distribution and mechanical strength. The shape accommodates symmetric radial stresses and simplifies enclosure design.
