The R911321151 (MSK075E-0450-FN-M2-UG1-RNNN) is an IndraDyn S synchronous servomotor from Bosch Rexroth featuring liquid cooling, a plain shaft, and a rotatable power connector. It is equipped with an electrically released 23 Nm holding brake operating at 24 V DC, 0.79 A. The motor integrates an optical multiturn absolute encoder with EnDat2.1 interface, 2048 signal periods resolution, and a 240° rotatable connector. The shaft incorporates a sealing ring to protect the bearings from dust and moisture. The aluminum die-cast design includes a coolant duct requiring a minimum flow rate of 1.5 l/min. Key electrical ratings include a winding code 0450, continuous current at standstill of 15.6 A, continuous torque at standstill of 23.0 Nm, maximum current of 63.9 A, and maximum torque of 88.0 Nm, with a winding inductivity of 4,460 mH.

Frequently Asked Questions

How does liquid cooling in the MSK075E-0450-FN-M2-UG1-RNNN improve torque consistency?

Liquid cooling keeps winding temperature stable. This ensures consistent torque delivery during extended high-load operation.

Why is a 2048-signal-period encoder beneficial for the IndraDyn S motor?

The encoder provides precise rotor feedback. This ensures smoother motion control and minimal positional error.

How does the EnDat2.1 interface in MSK075E-0450-FN-M2-UG1-RNNN support reliable communication?

The EnDat2.1 transmits absolute position digitally. This ensures accurate feedback and improved noise immunity in harsh environments.

Why is a rotatable 240° connector important in this servomotor?

The connector allows flexible cable orientation. This ensures easier installation within compact or complex machine layouts.

How does a 23 Nm holding brake benefit the IndraDyn S servomotor?

The brake secures the shaft during power loss. This ensures safe machine positioning and prevents drift on shutdown.
