MSK101D-0450-NN-M1-BP2-NNNN
MSK IndraDyn S Synchronous Motors
MSK101D-0450-NN-M1-BP2-NNNN, Bosch Rexroth Indramat, MSK IndraDyn S Synchronous Motors offers a high-performance servo solution in a compact footprint. This Product Type features a Motor Size of 101 with a Rated Speed Code of 0450, delivering precise motion control in demanding industrial settings. Engineered with a Design classification of Standard and cooled by Cooling via natural convection, it eliminates the need for auxiliary fans or complex thermal systems. The sturdy housing integrates a Power Connector on the B-Side for secure power feed and seamless machine integration.
In continuous operation at 100 K, the motor provides a Continuous Current at Standstill 100 K of 50.6 A and a Continuous Torque at Standstill 100 K of 57.0 Nm, while peak performance reaches a Maximum Current of 187.7 A and a Maximum Torque of 160.0 Nm. The robust Winding Inductivity of 1,700 mH ensures smooth current transitions and fine velocity regulation. Position feedback is handled by an advanced Encoder Technology optical system with Encoder Turn Type multiturn absolute sensing, an industry-standard Encoder Interface Hiperface, and a resolution of 128 signal periods per revolution. Safety and hold-in-place integrity come from a built-in Holding Brake that is electrically released, delivering Holding Brake Torque of 70 Nm under power-off conditions.
Designed for fault-tolerant servo networks, this motor meets the Constraint requirement for cooling FN, ensuring reliable operation across variable ambient conditions. The Shaft Type with keyway facilitates direct coupling to gearboxes or load shafts, streamlining assembly and maintenance. With its proven Bosch Rexroth Indramat pedigree, the MSK101D-0450-NN-M1-BP2-NNNN enhances system uptime, simplifies integration into existing controllers, and delivers consistent torque for precision positioning in robotics, packaging, and CNC applications.

Frequently Asked Questions
Why is natural convection cooling (no fan) chosen over forced cooling in this motor?
The natural convection eliminates moving parts, reducing maintenance and failure points. It is sufficient given the motor’s thermal design and continuous power dissipation limits.
What is the function of the 70 Nm electrically released holding brake in MSK101D-0450-NN-M1-BP2-NNNN motor?
In power-off conditions the MSK101D-0450-NN-M1-BP2-NNNN motor mechanically locks the shaft, preventing back-driving of the load. On power-up the brake releases quickly, resuming motion with minimal delay.
What applications are common for the MSK101D-0450-NN-M1-BP2-NNNN motor?
The MSK101D-0450-NN-M1-BP2-NNNN motor is widely used in CNC axes, robotics joints, and high-speed packaging machines due to its high torque, compact frame, and absolute encoding. Its torque density and robustness suit dynamic industrial tasks.
Why is the shaft keyed rather than smooth in this IndraDyn S model?
A keyway ensures positive torque transmission to gearboxes or couplings, preventing slippage under high torque loads. It simplifies mechanical alignment under load.
What is the advantage of using an absolute rather than incremental encoder in this motor?
The absolute encoders preserve the exact rotor position upon power-off or fault, eliminating rehoming routines. This reduces downtime and enhances system resilience.
