The Bosch Rexroth synchronous servo motor MPN R911321150 (MSK075E-0300-FN-S2-UG0-RNNN) is designed for high precision motion control applications. It has a plain shaft with shaft sealing and supports installation in multiple orientations via four standard through holes. This model utilizes a single-turn optical EnDat 2.1 encoder, providing 2048 signal periods per revolution. Electrical connections are facilitated by rotatable plugs with 240° adjustment. The motor offers a continuous standstill torque of 23.0 Nm at 15.6 A (100 K), a maximum torque of 88.0 Nm, and a maximum current of 63.9 A. The winding inductance is specified at 4,460 mH. The shaft run-out and axial run-out comply with DIN 42955 increased concentricity standards. It is specified for operation within an ambient temperature range of 0–40°C, and cooling is achieved through liquid cooling. No holding brake is included in this configuration.

Frequently Asked Questions

How does liquid cooling benefit the MSK075E-0300-FN-S2-UG0-RNNN motor’s performance?

Liquid cooling enhances heat dissipation, allowing the motor to sustain higher torque levels during continuous operation. It also ensures stable thermal management, reducing wear and extending service life.

Why is a 240° rotatable encoder connector advantageous in this motor?

The rotatable design provides flexible cable routing, simplifying installation in space-limited assemblies. It also reduces mechanical strain on connectors during maintenance or reconfiguration.

How does the optical encoder in the MSK075E-0300-FN-S2-UG0-RNNN improve accuracy?

Optical encoders offer precise position feedback with minimal signal noise. This ensures smoother control in demanding automation or motion systems.

What is the benefit of using the EnDat 2.1 interface in this motor?

The EnDat 2.1 interface provides digital, bidirectional communication between motor and controller. It allows for faster data transfer and integrated diagnostics for improved reliability.

How does the singleturn encoder configuration affect the MSK075E-0300-FN-S2-UG0-RNNN’s operation?

Singleturn encoders measure position within one motor revolution, providing high precision for short, repetitive movements. They are ideal where multi-turn tracking is unnecessary.
