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.

The Rexroth Indramat’s MSK100A-0300-NN-M1-BP0-NNNN servo motor maintains ambient thermal range through natural-convection and it relies on optical multiturn encoder that offers 128-period feedback. It comes with B-side power termination and possess keyed shaft for simplified integration. This motor features 17.0 Nm of continuous torque and 54.0 Nm of peak torque to suits CNC machining, packaging/printing lines, robotic axes and metal-forming cells.
