The Bosch Rexroth Indramat MSK050B-0450-NN-S1-UP0-NNNN is part of the MSK IndraDyn S Synchronous Motors series and embodies the robust precision of the Product Type IndraDyn S Synchronous Servomotor family. This Standard design features a motor size 050 frame with a motor length B profile and a shaft type Shaft with keyway for secure torque transmission. Rated at a speed code 0450, the unit delivers dynamic motion control without a holding brake while relying entirely on natural convection for passive cooling. Its compact footprint and modular architecture facilitate straightforward mounting in diverse automation cabinets and motion assemblies.
An integrated optical encoder employs a singleturn mechanism paired with a Hiperface interface to guarantee high-resolution feedback and minimal latency. The encoder’s rotatable, 240° connector simplifies cable routing in tight installations, and its 128 signal periods ensure precise position monitoring down to sub-micron increments. On the power side, the MSK050B-0450-NN-S1-UP0-NNNN sustains a maximum current of 11.2 A and can deliver a maximum torque of 9.0 Nm for peak performance. For stationary holding at 100 K, it provides a continuous current at standstill of 3.2 A and a continuous torque at standstill of 3.4 Nm, supporting secure load retention under static conditions.
With a substantial winding inductivity of 33,600 mH, this servomotor offers exceptionally smooth current transitions and low electrical ripple under dynamic acceleration and deceleration. The combination of thermally resilient windings and passive natural convection cooling ensures uninterrupted operation in temperature-sensitive applications without the need for forced-air systems. Designed for seamless integration with Bosch Rexroth Indramat drives and controllers, the MSK050B-0450-NN-S1-UP0-NNNN is ideal for precision robotics, packaging machinery, and high-performance positioning systems where durability and feedback accuracy are paramount.
