The Bosch Rexroth MPN R911321027 (MSK070E-0300-NN-M2-UP1-RNNN) is an IndraDyn S synchronous servomotor featuring a shaft with keyway and electrically released holding brake providing 23 Nm holding torque at 24 VDC. It employs a multiturn absolute optical encoder with EnDat 2.1 interface, supporting 2048 signal periods and up to 4096 revolutions, operable at a maximum speed of 12,000 RPM with a DC supply between 7–12 V. The motor's size is 070 with motor length E and incorporates rotatable 240° encoder connectors. Continuous current at standstill (100 K) is 16.7 A, continuous torque 25.0 Nm, maximum current 49.3 A, and maximum torque 65.0 Nm. Winding inductivity is 3,900 mH. Cooling relies on natural convection, and the design ensures increased concentricity. The motor is intended for operation in 5–95% relative humidity, recommended ambient temperatures from 0 to 40°C, with derating between 45–55°C and at altitudes from 1000 to 3000 meters. Power and feedback use separate cabling to the drive controller.

Frequently Asked Questions

What advantage does the 240° rotatable encoder connector offer?

The 240° rotatable encoder connector provides flexible mounting options. This helps with motor integration in various configurations or limited-space installations.

How does the natural convection cooling system support motor longevity?

Natural convection cooling reduces overheating risks. This supports longer motor life and consistent performance in environments with low airflow.

How does the 2048 signal periods encoder resolution affect feedback precision?

The 2048 signal period encoder resolution ensures ultra-fine position tracking. This allows for more accurate and responsive control over motor movements.

Why is a multiturn encoder beneficial in high-demand industrial applications?

A multiturn encoder tracks position over multiple rotations. This ensures accurate feedback even in systems requiring continuous, high-precision motion.

How does the increased concentricity affect motor vibration?

Increased concentricity ensures more even rotation. This minimizes vibration that improves smoothness and reducing wear on motor components.
