The R911376955 (MSK050C-0300-NN-M1-UP0-NSNN) is a Bosch Rexroth IndraDyn S synchronous servomotor, motor size 050 and length C, with a winding code of 0300. It features a shaft with a DIN 6885-1 keyway, provides a continuous torque at standstill of 5.5 Nm and a maximum torque of 15 Nm, with a continuous current at standstill of 3.4 A and a maximum current of 12.4 A. Stator temperature is monitored via integrated sensors, and encoder technology is multiturn absolute, optical, Hiperface interface, offering 128 signal periods and a rotatable connector (240°). The motor is cooled by natural convection, complies with Device Group II and IP65 standards, and is resistant to salt mist and ice formation. It weighs 5.4 kg, does not include a holding brake, and should be handled using eyebolts or chain suspension to avoid damage. Visual bearing inspection is recommended annually.

Frequently Asked Questions

Does the MSK050C-0300-NN-M1-UP0-NSNN support clean cabinet designs with simplified wiring paths?

It features a 240° rotatable encoder connector, ideal for tight-space routing. This improves assembly flexibility without compromising signal orientation.

What position feedback reliability can I expect in high-precision axis applications?

The Hiperface multiturn absolute optical encoder ensures accurate shaft tracking across power cycles. It integrates both power and communication through a single connector.

How can the MSK050C-0300-NN-M1-UP0-NSNN be used in silent or sealed machinery?

The natural convection cooling enables fanless, low-noise operation. It's suitable for environments with noise restrictions or cabinet airflow constraints.

What current behavior should be expected during prolonged standstill phases?

It draws 3.4 A under standstill conditions to maintain holding torque. Proper thermal planning is advised to avoid buildup during dwell time.

Can this motor be used for vertical or safety-relevant axes requiring passive shaft locking?

It lacks a holding brake and cannot retain position without active torque. External braking or mechanical locking is required in fail-safe scenarios.
