The Bosch Rexroth R911334593 (MPN: MSK101D-0300-FN-M2-BG2-RNNN) is an IndraDyn S synchronous servomotor from the MSK series, featuring liquid cooling and a B-side power connector. It includes an optical multiturn absolute encoder (EnDat 2.1, 2048 signal periods) with ±20 angular seconds accuracy. The motor has a plain shaft, a length D housing, and a 101 mm frame size. Continuous current at standstill (100 K) is 34.9 A, delivering 57.0 Nm continuous torque, with peak figures of 137.7 A and 160.0 Nm. An electrically released 70 Nm holding brake is integrated. The unit provides IP65 protection and is suitable for ambient temperatures 0°C to 40°C and installations up to 1000 m altitude. Winding code is 0300 with an inductance of 3,200 mH.

Frequently Asked Questions

What precautions are needed for using the electrically released 70 Nm holding brake?

The brake must be driven by a dedicated DC supply and released before motion; mis-timing brake release vs motor torque can stall or jerk the system.

How does the plain shaft influence coupling choices in high-speed applications?

Without a keyed or flanged hub, you’ll need shrink disk, clamp, or flexible couplings that maintain concentricity, especially at high RPMs.

What thermal limitations should be considered under continuous duty?

The motor’s thermal time constant and liquid cooling capacity set limits—exceeding its continuous rating without enough cooling can cause insulation degradation.

What is the impact of the 3,200 mH winding inductance on servo loop tuning?

High inductance smooths current ripple but slows current slew rate, requiring slower PI current loops and careful feedforward compensation.

How does the “increased concentricity” design benefit dynamic accuracy?

Tighter rotor/stator alignment reduces eccentricity-induced disturbances, improving repeatability under acceleration and load changes.
