The Bosch Rexroth R911311681 (MSK050C-0300-NN-M2-UP0-RNNN) is an IndraDyn S synchronous servomotor featuring a frame size of 050 and a length code C. It is capable of a maximum speed of 4300 RPM, with a continuous standstill current of 1.8 A and torque of 3 Nm at 60 K, increasing to 2.0 A and 3.4 Nm at 100 K. Maximum values reach 7.2 A current and 9 Nm torque; design specifications include a winding code of 0300 and winding inductivity of 45.1 mH. The shaft features a keyway; there is no holding brake. The motor employs an optical multiturn absolute encoder with 2048 signal periods via EnDat 2.1, using a rotatable 240° connector. The IP65-rated housing provides protection against dust and moisture, and enables cooling by natural convection or forced air. The assembly weighs 4 kg and offers enhanced run-out and concentricity.

Frequently Asked Questions

Does the MSK050C-0300-NN-M2-UP0-RNNN allow high-resolution position control in servo feedback loops?

It uses an optical multiturn absolute encoder with EnDat2.1 interface. This enables high-precision tracking across cycles with single-cable data and power transfer.

How well does this model dissipate heat in fanless cabinet designs?

The natural convection cooling supports continuous operation without forced ventilation. It's suitable for sealed enclosures where airflow is limited.

How does the MSK050C-0300-NN-M2-UP0-RNNN respond to intermittent torque spikes in indexing tasks?

It handles up to 15.0 Nm peak torque reliably. This accommodates short-duration load surges without compromising motor health.

Can I maintain stable torque output under constant-load positioning conditions?

It delivers 5.5 Nm continuous torque for precise holding during dwell states. This ensures consistent performance across sustained positioning cycles.

What effect does the winding inductivity have on system dynamics in responsive applications?

A 45.100 mH inductivity smooths current ripple and improves low-speed control. It may introduce slight lag during fast dynamic shifts.
