Product Description:

The MSK050B-0300-NN-S1-UP1-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. This model belongs to motor size 050 and uses length code B, which gives it a compact mechanical envelope for tightly spaced axes and similar motion assemblies. It is intended for precision motion tasks in industrial automation where closed-loop speed and position control are required. In typical use, the motor works with a compatible drive to provide controlled acceleration, stable running speed, and repeatable positioning on automated equipment.

Thermal management relies on natural convection, so heat dissipates through the housing without fans or liquid circuits. The encoder connector is rotatable through 240°, allowing the cable exit to be aligned with cabinet or drag-chain layouts and reducing tight bends near the connection point. Feedback signals are exchanged over the Hiperface interface, which carries position data for closed-loop control over a compact feedback link. The optical sensor provides 128 signal periods per mechanical revolution, and the drive can use interpolation to achieve finer position resolution during motion. The encoder technology is optical, which supports stable signal quality and avoids magnetic sensing elements.

The encoder is a single-turn device, so it reports absolute angle information within one full revolution while the control system tracks additional turns separately. An electrically released holding brake supplies 6 Nm of static torque, which helps hold a vertical or indexing axis in place after power is removed. Power is transmitted through a shaft with keyway, allowing the motor to connect to standard keyed couplings for positive torque transfer. The motor uses winding code 0300, which corresponds to the electrical data expected by compatible IndraDrive combinations. It follows the standard design variant and uses a common optical feedback cartridge in this product range.
