The Bosch Rexroth Indramat MSK071C-0300-NN-M3-UG0-NNNN motor from the MSK IndraDyn S Synchronous Motors series is a compact IndraDyn S Synchronous Servomotor designed for precision control. It features a motor size of 071 and a motor length C, delivering a maximum torque of 44.0 Nm and continuous torque at standstill (100 K) of 14.0 Nm. The drive supports a maximum current of 32.9 A and continuous current at standstill (100 K) of 8.5 A. Natural convection cooling ensures reliable thermal management, while a plain shaft design simplifies integration. The multiturn absolute capacitive encoder uses the Hiperface interface with 16 signal periods resolution and a rotatable, 240° connector, providing robust feedback. This standard design servomotor comes without a holding brake, facilitating versatile installations.

Frequently Asked Questions

What encoder architecture is on MSK071C-0300-NN-M3-UG0-NNNN, and how does it influence control loops?

It employs a multiturn absolute capacitive encoder with Hiperface and 16 signal periods that supplys deterministic position over multiple revolutions. Its stable absolute feedback tightens velocity/position loops and reduces homing cycles after power events.

How does natural-convection cooling affect sizing and duty on the MSK071C-0300-NN-M3-UG0-NNNN?

Its passive heat rejection sets thermal limits of enclosure airflow and mounting surfaces rather than forced cooling hardware. Its correct thermal modeling preserves the specified 14 Nm continuous torque at standstill (100 K) without fan maintenance.

How does the plain-shaft configuration impact coupling design on MSK071C-0300-NN-M3-UG0-NNNN?

The keyed/plain shaft simplifies use with standard zero-backlash couplings and planetary gear inputs. Its proper misalignment compensation and radial-load verification keep bearing life within L10h targets from Rexroth guidance.

What are the current limits and their implications for drive selection on MSK071C-0300-NN-M3-UG0-NNNN?

Its maximum current is 32.9 A and continuous at standstill is 8.5 A that dictates inverter current class and cabling gauge. It ensures the IndraDrive module supports these peaks while respecting thermal time constants.

How does winding inductivity (≈10,900 mH stated) influence servo performance and filtering on MSK071C-0300-NN-M3-UG0-NNNN?

The winding inductance shapes current-loop bandwidth and dictates dV/dt filtering needs with long motor cables. Its drive autotuning uses this parameter to stabilize current regulators while maximizing dynamic torque response.
