The Bosch Rexroth R911372281 (MSK101D-0300-NN-S1-RG0-NNNN) is an IndraDyn S series synchronous servomotor with frame size 101 and motor length D. It features a plain, chemically resistant shaft, an optical single-turn encoder (Hiperface interface, 128 signal periods), and includes a temperature sensor. The motor provides a maximum speed of 4,600 rpm, maximum torque of 160 Nm, and continuous torque at standstill of 57 Nm (100 K). The winding code is 0300, with winding inductance of 3,200 mH and a continuous current at standstill of 34.9 A. Voltage constant is 113 V/min⁻¹, torque constant is 1.80 Nm/A at 20°C, and noise emission stays under 75 dB. The unit is self-cooling, finished in RAL9005 black epoxy, designed for ambient temperatures from 0°C to 40°C, and installation altitudes up to 1000 m. The power connector is positioned on the right side; no holding brake is included.

Frequently Asked Questions

Why is the MSK101D-0300-NN-S1-RG0-NNNN servomotor used in CNC or robotics?

The combination of 57 Nm continuous torque, precise Hiperface feedback, and compact design of MSK101D-0300-NN-S1-RG0-NNNN servomotor makes it ideal for axes in CNC or robotic arms with high repeatability.

How does ambient temperature influence the MSK101D-0300-NN-S1-RG0-NNNN servomotor operation?

The MSK101D-0300-NN-S1-RG0-NNNN servomotor is rated for ambient 0–40 °C; exceeding this reduces thermal margin. A hotter environment shortens safe current limits and lifetime.

What is the bearing lifetime under design limits?

The bearing lifetime (L10h) is targeted at 30,000 operating hours if radial and axial loads stay within specified bounds. Exceeding limits or poor lubrication reduces expected life

Why is a plain shaft chosen for MSK101D-0300-NN-S1-RG0-NNNN servomotor?

A plain shaft in MSK101D-0300-NN-S1-RG0-NNNN servomotor reduces backlash and torsional play in coupling. It allows clamping or shrink-fit elements to mount loads more rigidly.

How does the 3,200 mH winding inductance affect performance?

The 3,200 mH inductance damps current ripple and smooths torque transition. It also influences dynamic response and filter design in the drive electronics.
