MSK101C-0300-NN-M1-BP0-NNNN
MSK IndraDyn S Synchronous Motors
The MSK101C-0300-NN-M1-BP0-NNNN, Bosch Rexroth Indramat, MSK IndraDyn S Synchronous Motors series offers a high-performance, modular servomotor solution designed for precision motion control. This IndraDyn S Synchronous Servomotor features a Motor Size of 101 and a Motor Length designation of C, delivering dynamic response without compromise. With a Rated Speed Code of 0300, the unit achieves rapid acceleration profiles while maintaining positional accuracy. The motor’s Design is optimized for compact integration in high-density machine architectures.
Equipped with Natural convection Cooling, the MSK101C operates maintenance-free across a broad temperature range. It includes a robust Shaft Type of Shaft with keyway and a Power Connector on the B-side for streamlined cabling. The integrated Hiperface Encoder Interface provides high-resolution feedback at 128 signal periods, ensuring repeatable positioning. Continuous current ratings reach 28.1 A at standstill and 18.7 A at 60 K, producing 48.0 Nm of torque at standstill and 36.5 Nm at 100 K. Peak performance is marked by a Maximum torque of 110.0 Nm and a Voltage constant at 20°C of 115.7 V/1 000 min-1.
The standard Without holding brake variant simplifies system design and reduces overall mass, while its rugged construction supports reliable operation in industrial environments. Seamless compatibility with Bosch Rexroth IndraDrive controllers facilitates rapid commissioning and plug-and-play integration. Engineers benefit from the motor’s consistent torque delivery, high overload capacity, and low acoustic profile, making it an ideal choice for packaging machines, robotics, and dynamic assembly systems where uptime and precision are paramount.

Frequently Asked Questions
When is natural-convection cooling appropriate for the MSK101C-0300-NN-M1-BP0-NNNN, and what are the sizing implications?
The convection is suited to moderate thermal loads where airflow around the frame is unobstructed for avoiding fans and associated maintenance. For higher duty cycles, consider forced-air/surface-cooled MSK variants to maintain continuous torque without exceeding thermal limits.
How does the B-side power connector on MSK101C-0300-NN-M1-BP0-NNNN aid machine layout and EMC practices?
The side-B feed allows cleaner cable routing away from moving elements for simplifying bend-radius management and separation from feedback lines. Its shorter, segregated runs reduce common-mode noise and ease panel integration with IndraDrive hardware.
Why choose the “shaft with keyway” option on this MSK101C variant instead of a plain shaft?
The keyed shaft provides positive torque transmission and repeatable hub alignment That is useful for couplings and belt pulleys. Its plain shafts are available on related MSK101C variants when backlash, sealing or alternative hub designs are prioritized.
How does the encoder data memory simplify commissioning this motor on IndraDrive systems?
The Rexroth motors store key parameters in the encoder; when connected, IndraDrive reads them and auto-sets motor protection and base settings. It accelerates startup and lowers parameterization errors for MSK machines.
What does the voltage constant (≈115.7 V per 1000 min⁻¹) imply for MSK101C-0300-NN-M1-BP0-NNNN in DC-bus and regen sizing?
The back-EMF scales with speed, while the voltage constant helps verify margin versus the drive’s DC-bus under maximum operating rpm. It also informs braking-chopper and resistor selection to safely dissipate regenerated energy.
