The R911321968 (MSK040B-0450-NN-S1-UG1-NNNN) is a Bosch Rexroth IndraDyn S synchronous servomotor with a motor size of 040 and motor length B. It features natural convection cooling, a plain shaft, and a standard design. Electrical connection is universal across frame sizes. The motor operates within an ambient temperature range of 0 to 40°C and is equipped with an optically based singleturn encoder (Hiperface interface, 128 signal periods, 240° rotatable connector). Specifications include a maximum speed of 6000 RPM, maximum current of 6.0 A, maximum torque of 5.1 Nm, continuous current at standstill (100 K) of 1.7 A, continuous torque at standstill (100 K) of 1.9 Nm, and a winding inductivity of 64,700 mH. The voltage constant is 77.8 V/min⁻¹ at 20°C. An electrically-released holding brake provides 4 Nm of torque and requires inspection before installation. The unit weighs 3.1 kg, maintains a noise level below 75 dB, is rated to IP65, and has an insulation class of 155.

Frequently Asked Questions

What distinguishes the Bosch Rexroth Indramat MSK040B-0450-NN-S1-UG1-NNNN from similar motors

The combination of convection cooling and integrated brake makes it well suited for compact automation cells. The motor balances torque delivery with low maintenance needs.

Why is a singleturn encoder sufficient for many industrial automation tasks?

The encoder resolves position within one revolution with fine accuracy. The setup suits packaging and robotic arms where only short-cycle precision is required.

How does continuous torque capability at standstill improve performance in servo-driven processes?

The torque at zero speed allows stable clamping and pressing operations. The process continues without vibration or torque drop.

What impact does the plain shaft design have on application adaptability?

The plain shaft allows straightforward coupling with external gears or pulleys. The design fits well in modular drive systems.

In which industries is this synchronous motor most commonly integrated?

The motor is used in packaging lines where accuracy is vital. The same motor also supports machine tools and printing presses.
