MS2N03-D0BYN-CSSK0-NNANN-NN

The Bosch Rexroth Indramat MS2N03-D0BYN-CSSK0-NNANN-NN from the MS2N Synchronous Servo Motors series features a Winding Code BY and a Number of Phases 3 design for high-precision motion control. Its Insulation Class 155 ensures robust electrical protection, while the half-key Motor Balancing method minimizes vibration. Rated for installation at elevations from 0 to 1000 m Above Sea Level, the motor can be stored horizontally according to its Transportation and Storage Orientation specification without compromising performance. After extended storage, it reliably restarts up to Run-In Speed After Storage 1000 RPM.

Externally, the motor is built around a Keyway Output Shaft Type of 23 mm Output Shaft Length and a Cylindrical Shaft End for easy coupling with transmission elements. Its single-turn encoder design (as noted in the product description) complements the DS M5 centering hole per DIN 332 on the shaft end. Although this unit is not equipped with a holding brake, the fixed bearing on Side B and the M23 single-cable electrical connection provide secure mechanical and electrical interfaces. Provisions for a minimum 100 mm clearance around the housing allow for adequate vertical convection cooling when installed with the output shaft facing up or down.

For safe handling, note that the motor’s hot surface temperature can exceed 60 °C during operation; protective gloves and a cooldown period are mandatory before maintenance. The device must be worked on only in standstill mode, with plug connections made or broken exclusively in the de-energized state. Bearing replacement is recommended after 30 000 operating hours to sustain performance and longevity. This synchronous servo motor must be replaced only by an identical type and should not be operated directly on a three-phase network.
