The Bosch Rexroth MPN R911377455 (MSK100D-0300-NN-M2-LP2-RNNN) is an IndraDyn S synchronous servo motor from the MSK series featuring a 100 frame size and D-length housing. It provides continuous torque up to 57 Nm at 100 K with a continuous current of 24.8 A, reaching a maximum torque of 187 Nm and maximum current of 93.2 A. The unit uses natural convection cooling and incorporates an optical multiturn absolute encoder with EnDat 2.1 interface, 2048 signal periods, and a left-side power connector. The shaft includes a keyway and a shaft seal, with an electrically released holding brake rated at 70 Nm. The motor housing is designed for high concentricity, is not available in length A, and has an IP65 ingress protection rating. Operating parameters include an ambient temperature of 0 to 40°C and an elevation up to 1000 meters.

Frequently Asked Questions

How does the MSK100D-0300-NN-M2-LP2-RNNN ensure safe shaft locking in vertical or suspended axes?

It includes a 70 Nm electrically released holding brake. This prevents unintentional motion and secures the load during shutdown or fault conditions.

What enables precise multi-turn feedback in synchronized drive applications?

The optical multiturn absolute encoder with EnDat2.1 interface delivers 2048 signal periods. This ensures accurate positioning over multiple revolutions with high signal resolution.

How does the MSK100D-0300-NN-M2-LP2-RNNN maintain thermal balance in fully enclosed control enclosures?

It uses natural convection cooling to manage internal temperatures passively. This allows fanless integration while preserving continuous torque delivery under normal load.

What mechanical benefit supports clean integration into rigid couplings and linear drives?

The motor features a plain shaft for backlash-free engagement. This ensures precise torque transfer and alignment in direct-drive or servo-driven assemblies.

How does the left-side connector design optimize control cabinet layout in lateral-mounted systems?

It includes a left-side power connector to simplify wiring paths. This improves accessibility and routing efficiency in densely packed or narrow control enclosures.
