The R911330444 (MSK101D-0300-FN-S1-AP0-NNNN) is a Bosch Rexroth IndraDyn S synchronous servo motor designed for applications involving high-load repetitive operations. This liquid-cooled unit features a 101 motor size and D motor length with a shaft that incorporates a keyway and radial sealing ring for torque transmission and fluid ingress protection. It integrates an optical Hiperface singleturn encoder, providing ±80 angular second accuracy, 128 signal periods, and automatic communication of motor-specific data. The motor delivers up to 160.0 Nm maximum torque, 34.9 A standstill current, and supports a maximum speed of 4,600 rpm. Its continuous torque at standstill is 57.0 Nm, and winding inductivity is 3,200 mH. The motor is equipped with a KTY84 thermal sensor for overload protection and achieves IP65 protection in accordance with EN 60529. The design is standard and lacks a holding brake.

Frequently Asked Questions

How does the 57 Nm continuous torque rating translate to industrial motion tasks?

It means the motor can sustain ~57 Nm indefinitely (at rated current) under proper cooling. That suffices for many CNC or robot axes where intermittent peaks fall within its 160 Nm capability.

What drive current capability is needed to realize the full 160 Nm torque?

The motor requires up to 137.7 A peak current to achieve 160 Nm output. Your servo amplifier must support that current headroom with minimal voltage drop.

In what scenarios would the shaft keyway design affect coupling to load?

The shaft-with-keyway supports high torque loads and resists torsional slip, making it ideal for gearboxes or direct-drive setups. But ensure key tolerances and alignment minimize stress concentration.

How can thermal sensors (e.g. KTY84) be leveraged in system control?

You can integrate the KTY84 output into your drive logic to monitor motor winding temperature in real time. This enables dynamic derating under overheating conditions before catastrophic failure.

How does the optical Hiperface singleturn encoder affect startup routines?

The encoder provides absolute reference immediately on power-up, eliminating the need for homing routines. That reduces machine initialization time, especially in multi-axis systems.
