MSK101E-0300-FN-M1-RG2-NNNN

The Bosch Rexroth Indramat MSK101E-0300-FN-M1-RG2-NNNN is a high-performance synchronous servomotor in the MSK IndraDyn S Synchronous Motors series, engineered for precision motion control in demanding industrial environments. Manufactured by Bosch Rexroth Indramat, this model delivers robust torque and speed regulation through advanced control algorithms and a compact mechanical design. With a nominal torque constant of 1.85 Nm/A at 20 °C and a maximum current capacity of 187.4 A, the motor supports dynamic load handling and rapid acceleration profiles. Its versatile configuration makes it suitable for a wide range of applications, from machine tools to high-speed handling equipment. The MSK101E-0300-FN-M1-RG2-NNNN combines reliable mechanical integrity with sophisticated electronic commutation for spark-free operation in hazardous areas.

Detailed technical characteristics define the motor’s capabilities and integration requirements. The unit employs Liquid cooling to maintain optimal thermal performance under continuous operation. Electrical connectivity is provided via a Right-Side power connector, while position feedback is achieved through a high-resolution Hiperface encoder interface with 128 signal periods and Optical encoder technology in a Multiturn Absolute configuration. The drive features a Motor Length: E and a Motor Size: 101 housing, complying with the Standard design of the IndraDyn S servomotor family. For applications requiring emergency holding, the motor is equipped with With holding brake, electrically-released hardware delivering 70 Nm of brake torque. Key winding parameters include Winding Code: 0300, Winding Inductivity: 1,960 mH, and thermal constraints denoted by Requires Cooling FN. Performance limits feature a Continuous Current at Standstill 100 K: 47.8 A and Continuous Torque at Standstill 100 K: 80.5 Nm, with a peak Maximum Torque: 231.0 Nm.

Operational features emphasize stability, responsiveness, and environmental resilience. The motor achieves a maximum speed of 4600 rpm, leveraging enlarged air gaps to enhance mechanical stability at high rotational rates. Electronic commutation replaces brushed designs, ensuring consistent torque delivery and eliminating spark generation in sensitive installations. The integrated sealing kit maintains a controlled overpressure barrier against moisture, enabling reliable operation in humid or contaminated atmospheres. The thermal time constant of approximately five minutes supports predictable temperature rise during peak demand, while the system tolerates overtemperatures of up to 60 K and 100 K without performance degradation. Optimal performance is maintained in ambient air temperatures not exceeding 40 °C.

System integration is facilitated through compatibility with Rexroth IndraDrive controllers and drive software, enabling seamless communication and real-time diagnostics. The servomotor’s plain shaft interface and standardized mounting dimensions simplify retrofits and modular machine designs. Target applications include woodworking machinery, printing and paper handling systems, precision assembly lines, and CNC machine tools where high torque density, positional accuracy, and functional safety are paramount. The MSK101E-0300-FN-M1-RG2-NNNN stands as a reliable platform for automation solutions requiring stringent performance and environmental robustness.
