The R911374859 (MSK101C-0450-FN-M2-AG2-RNNN) is a Bosch Rexroth IndraDyn S synchronous servomotor designed for environments requiring liquid cooling (cooling type FN) and a plain output shaft. This motor features a size code of 101 and motor length C, with a winding code of 0450. It supports continuous current at standstill of 28.6 A and continuous torque at standstill of 36.5 Nm at 100 K. Maximum current is rated at 113.0 A and maximum torque at 110.0 Nm. The holding brake is electrically released and delivers a torque of 70 Nm. The unit utilizes an EnDat2.1 optical multiturn absolute encoder interface with 2048 signal periods and a maximum current consumption of 250 mA. The design includes increased concentricity, an operating temperature range of 0°C to 40°C, and supports operation without a fan, achieving a motor housing temperature up to 155°C. Winding inductivity is 3,300 mH. Power connection is available at the A side.

Frequently Asked Questions

Why use an optical multiturn absolute encoder (EnDat 2.1, 2048 signal periods) on MSK101C-0450-FN-M2-AG2-RNNN instead of incremental feedback?

Multiturn absolute feedback retains position and revolution count at power-up for eliminating homing moves and reducing collision risk. Its EnDat 2.1’s bidirectional digital link carries diagnostics/parameters, while 2048 periods permit fine interpolation for smooth velocity loops.

How does the FN liquid-cooling variant in MSK101C-0450-FN-M2-AG2-RNNN influence continuous torque at standstill and thermal headroom?

The liquid circulation lowers thermal resistance to let the 36.5 Nm continuous torque at 100 K remain stable. Its improved heat removal increases duty-cycle headroom and defers thermal limiting if the specified coolant flow and temperature differential are maintained.

What advantages does the electrically-released 70 Nm holding brake provide on vertical or Z-axes?

The brake clamps the shaft to prevent load drift during power loss when de-energized for protecting tooling and payloads. Its electrical release during motion avoids drag, while 70 Nm static torque secures moderate inertial loads during emergency deceleration.

Is MSK101C-0450-FN-M2-AG2-RNNN compatible with Rexroth IndraDrive controllers and A-side power connectors?

Yes, the MSK motors are engineered for the IndraDrive ecosystem with standardized power/encoder plug connections for fast commissioning. Its A-side power orientation supports right-hand cable routing while maintaining bend-radius and strain-relief practices.

How does the EnDat 2.1 multiturn system on MSK101C-0450-FN-M2-AG2-RNNN aid maintenance and functional checks?

Its digital diagnostics, parameter memory and absolute position enable quick, deterministic axis verification after faults or service. It eliminates homing to reduce risk in collaborative cells and simplifies replacement logistics and traceability.
