The R911321727 (MSK050C-0300-NN-S2-UG1-RNNN) is an IndraDyn S series synchronous servomotor designed for applications requiring high torque density, precision, and dynamic performance. With a frame size of 050 and a length type C, it features natural convection cooling and encloses a single-turn optical encoder (EnDat2.1) with 2048 signal periods for feedback. The motor operates at a maximum speed of 4700 RPM, with a maximum torque of 15 Nm and a maximum current of 12.4 A. The plain shaft includes a seal for ingress protection, and a 6 Nm holding brake is fitted for controlled de-energization. The motor’s rotor inertia is 3.3 × 10⁻⁴ kg·m², and continuous standstill performance is rated at 3.4 A and 5.5 Nm at 100 K. Additional attributes include a 240° rotatable electrical connector and a winding inductivity of 45,100 mH.

Frequently Asked Questions

How does the MSK050C-0300-NN-S2-UG1-RNNN secure vertical loads or hold position during drive shutdown?

It includes a 6 Nm electrically released holding brake. This provides mechanical locking to prevent load drift during power-off or emergency stop states.

What feedback resolution can be expected from this model in position-critical motion loops?

It uses an optical EnDat2.1 encoder with 2048 signal periods. This delivers high-resolution absolute position tracking with digital robustness.

Can the MSK050C-0300-NN-S2-UG1-RNNN be used in passive-cooling automation cells?

It features natural convection cooling for heat dissipation. This allows quiet, fanless operation in sealed or maintenance-restricted environments.

How does the motor handle brief acceleration spikes without requiring oversizing?

It supports 15 Nm peak torque to handle transient loads. That provides the torque margin needed for rapid indexing or high-inertia starts.

Is the torque output stable for high-precision holding tasks under static load?

It delivers 5.5 Nm continuous torque at 3.4 A. This enables accurate, thermally consistent performance in position-hold or dwell applications.
