The Bosch Rexroth synchronous servomotor R911372678 (MSK101D-0300-NN-S3-AP0-NNNN) is designed for use in rotary main and servo drive applications. It features a maximum speed of 4600 RPM, a keyway shaft for torque transmission, and a sealing ring for environmental protection. Electrical characteristics include a resistance of 0.19 ohms, a winding inductance of 3.200 mH, a maximum current of 137.7 A, continuous current at standstill of 34.9 A (100 K), and maximum torque of 160.0 Nm, with continuous torque at standstill of 57.0 Nm (100 K). The motor operates at a maximum ambient temperature of +40°C and has a thermal time constant of 100 minutes. It utilizes a single-turn capacitive encoder (Hiperface interface, 16 signal periods), supports natural convection cooling, and offers a primary coating thickness of 40 microns. The design includes IP65 water resistance, insulation class 155, standard shaft with keyway, no holding brake, power connection on the A side, size 101, and D motor length. Sound pressure is rated at 75 dB.

Frequently Asked Questions

How does the capacitive Hiperface singleturn encoder improve accuracy?

The singleturn capacitive Hiperface encoder ensures minimal noise and drift in absolute position feedback. It maintains absolute angular reference within one revolution even after power cycles.

How does the winding inductance 3.2 mH of MSK101D-0300-NN-S3-AP0-NNNN servomotor affect servo performance?

The 3.2 mH inductance of MSK101D-0300-NN-S3-AP0-NNNN servomotor helps smooth current ripple and supports stable control loops. It also influences the motor’s electrical time constant and dynamic response.

What is the role of the motor’s thermal time constant (100 min)?

The 100 minute thermal time constant indicates how quickly the motor equilibrates temperature. It helps in predicting temperature rise under sustained loads.

How does the 101 frame and D-length affect mounting?

The 101 frame defines flange and shaft dimensions, while D-length sets axial size. These ensure compatibility across the MSK101 series and modular interchangeability.

What advantage does the A-side power connector provide to MSK101D-0300-NN-S3-AP0-NNNN servomotor?

The A-side connector of MSK101D-0300-NN-S3-AP0-NNNN servomotor centralizes cabling on one side of the housing, simplifying layout and service access. It helps align cable routing in compact installations.
