MSK101D-0450-NN-M1-AK0-NN02
MSK IndraDyn S Synchronous Motors
MSK101D-0450-NN-M1-AK0-NN02, Bosch Rexroth Indramat, MSK IndraDyn S Synchronous Motors represent a high-performance servomotor family engineered for precision motion control. With a compact Motor Size 101 and tailored Rated Speed Code 0450, this unit delivers exceptional dynamic response and positioning accuracy. The design omits a holding brake, enhancing mechanical simplicity and reducing maintenance points. Integrated A-Side Power Connector wiring streamlines installation and serviceability in tight cabinet layouts.
Detailing its thermal management, the motor employs Natural convection cooling to dissipate heat without auxiliary fans, ensuring silent operation and lower particulate ingress. An Optical encoder technology with a Multiturn Absolute turn type and Hiperface interface provides robust feedback, offering 128 signal periods resolution for sub-microradian control. The rotor and stator windings feature a high Winding Inductivity of 1,700 mH, stabilising current ripple under load. At 100 K, it sustains a Continuous Current at Standstill of 50.6 A and generates a Continuous Torque of 57.0 Nm, while peaking at Maximum Current 187.7 A for a Maximum Torque of 160.0 Nm during rapid accelerations.
Engineers appreciate seamless integration with IndraDrive controllers, leveraging standard Hiperface comms to synchronise multi-axis systems. The robust construction without a holding brake reduces mechanical complexity and enhances long-term reliability in continuous-duty applications. Ideal for robotics, packaging, and CNC machinery, the MSK101D-0450-NN-M1-AK0-NN02 improves throughput and precision with minimal footprint.

Frequently Asked Questions
Why is a holding brake electrically released rather than mechanically in this motor?
An electrically released brake is held closed by default in absence of power, ensuring safe holds during power loss. It releases only when driven, which is ideal for safety in motion systems.
What role does the 1,700 mH inductance play in this motor?
The 1,700 mH winding inductance helps filter current ripple and reduces torque ripple under PWM drive conditions. It also shapes the motor’s dynamic response and influences control loop tuning.
What is the torque constant of MSK101D-0450-NN-M1-AP2-NNNN motor and how is it useful?
The torque constant is about 1.32 Nm/A, linking electrical current to mechanical torque. It is essential for sizing the drive current and control gains in the servo system.
How does the 0.10 Ω winding resistance influence MSK101D-0450-NN-M1-AP2-NNNN motor behavior?
The low 0.10 Ω resistance of MSK101D-0450-NN-M1-AP2-NNNN motor ensures lower I²R losses, increasing efficiency under load. It also means the winding will have lower voltage drop at high currents, improving performance in heavy duty tasks.
How does the electrically released holding brake torque (70 Nm) benefit machine safety?
The 70 Nm holding torque ensures the load remains stable under no-power conditions, preventing drift. It provides sufficient margin against external forces in many robotic and CNC systems.
