Product Description:

Bosch Rexroth Indramat builds the MSK040B-0600-NN-S1-UG0-NNNN synchronous servomotor for tightly controlled motion axes in packaging, printing, and light assembly equipment. The unit belongs to the MSK IndraDyn S Synchronous Motors series and converts commanded current from a Rexroth inverter into accurate rotary motion for coordinated velocity and position loops. Its compact frame and standard mechanical layout help it fit into tight machine spaces, while the rotor’s surface magnets support fast torque response during high-cycle production. This type of motor is well suited to repeated indexing tasks where the control system must correct speed and position errors quickly.

The motor releases heat through natural convection, so no external fans or liquid circuits are required, which helps simplify use in sealed enclosures. Position feedback travels over the Hiperface interface, allowing absolute angle data and motor information to pass to the drive on the same connection. Inside the encoder, the disk produces 128 signal periods per mechanical revolution, which supports smooth low-speed operation and stable commutation. A plain shaft couples directly to pinions or bell housings, and the unit is supplied without a holding brake, so any static load retention must come from the drive or the machine’s own locking device.

The feedback system uses optical scanning to reduce electrical noise and support fine interpolation of each measured period. The code wheel is single-turn, so the absolute position repeats after one full revolution and is suitable where multi-turn tracking is not needed. Mechanical dimensions follow motor size 040, which keeps the stator compact for limited-space gantries and small automation axes. The motor uses winding code 0600, matching the electrical layout to compatible IndraDrive controllers that can supply the required current.
