MSK100A-0300-NN-M1-BP0-NNNN
MSK IndraDyn S Synchronous Motors
The Bosch Rexroth Indramat MSK100A-0300-NN-M1-BP0-NNNN is a high-performance servo motor from the esteemed MSK IndraDyn S Synchronous Motors series. Designed for precision motion control, this IndraDyn S Synchronous Servomotor features Natural convection cooling and an advanced Optical encoder technology. Its Multiturn Absolute encoder turn type and Hiperface interface provide reliable position feedback, making it ideal for demanding industrial automation applications such as CNC machining, robotics, and automated assembly systems.
This servomotor is built around a Motor Size 100 frame with a Motor Length A design, offering a compact yet powerful solution for modern drive systems. The Rated Speed Code 0300 denotes its optimized speed handling capability. At standstill and 100 K, it delivers a Continuous Current of 11.6 A and a Continuous Torque of 17.0 Nm, while a Maximum Current of 45.9 A and a Maximum Torque of 54.0 Nm support peak performance demands. The motor’s Winding Inductivity of 11,200 mH ensures stable current flow and smooth torque delivery. A robust Shaft with keyway and a B-Side Power Connector complete the mechanical and electrical interfaces, ensuring secure integration into drive units.
Built without a holding brake, the MSK100A-0300-NN-M1-BP0-NNNN offers streamlined integration where external braking is managed by system controllers or drive electronics. The standard Design emphasizes durability and maintenance-free operation, while Natural convection cooling eliminates the need for auxiliary fans or liquid circuits, reducing potential failure points. With an encoder resolution of 128 signal periods, this motor guarantees fine-grained control for high-precision positioning tasks. Engineers will appreciate its compatibility with common industrial drives and the benefit of continuous, efficient operation under varying load conditions. In industrial environments, this servo motor delivers exceptional reliability, precise speed and position control, and long-term operational efficiency, enhancing overall system productivity and reducing downtime.

Frequently Asked Questions
Why choose natural-convection cooling, and when would I add fans on this motor?
Its natural convection minimizes parts count and airflow dependency. It’s ideal where continuous losses are moderate and acoustic limits apply. For higher duty cycles, Rexroth specifies retrofit axial/radial blower units or liquid cooling to raise continuous torque without exceeding temperature rise.
What’s the benefit of the B-side power connector on MSK100A-0300-NN-M1-BP0-NNNN, and what ingress protection applies?
Its B-side routing eases cable dressing in certain cabinets and reduces bend-radius conflicts. Its connector carry IP66/IP67 ratings when correctly mated for supporting harsh environments with proper strain-relief and sealing practices.
How do 11.6 A continuous (100 K), 45.9 A peak, and 11,200 mH inductivity shape the drive setup on MSK100A-0300-NN-M1-BP0-NNNN?
Its current controllers and DC-bus components RMS/peak meet thermal rise and overload timing; the high inductivity reduces ripple and switching losses. Its current loops tuning helps the motor’s electrical time constant to avoid phase lag under regenerative events.
The encoder resolution lists “128 signal periods.” How does that translate into positioning with an IndraDrive?
The Hiperface’s 1 Vpp sin/cos tracks provide 128 mechanical periods; with drive-side interpolation, effective counts per revolution increase dramatically for improving velocity granularity and cogging suppression. It allows tighter position/velocity loop gains without quantization-noise penalties.
What does the “0300” speed code on MSK100A-0300-NN-M1-BP0-NNNN indicate in practice?
It denotes a winding/speed class defined in Rexroth tables; for the MSK100A-0300 variant the catalog lists a maximum speed around 5,200 rpm at a 750 V DC link. It is important to select gearing/inertia accordingly for bandwidth and thermal headroom.
