MSK100A-0200-NN-M1-BP0-NNNN
MSK IndraDyn S Synchronous Motors
The Bosch Rexroth Indramat MSK100A-0200-NN-M1-BP0-NNNN from the MSK IndraDyn S Synchronous Motors series is a precision-engineered IndraDyn S Synchronous Servomotor featuring a motor size 100 frame and a compact motor length A housing. This standard design motor is equipped with a robust shaft with keyway for secure coupling and a versatile B-Side power connector configuration. With a rating optimized for medium-duty automation, this model comes without holding brake to streamline integration in closed-loop systems. The unit’s natural convection cooling ensures quiet and maintenance-free operation under continuous loads.
Performance excellence is delivered through a rated speed code 0200 configuration, providing reliable operation at defined synchronous speeds. At 100 K, the motor sustains a continuous current at standstill of 10.4 A and generates a continuous torque at standstill of 17.0 Nm without derating. For dynamic loads, the rotor can tolerate a maximum current of 41.4 A and develop a maximum torque of 54.0 Nm in peak duty cycles. The high winding inductivity of 13,900 mH contributes to smooth torque production and reduced ripple, supporting precise motion control under variable acceleration profiles.
Precision feedback is achieved with an optical encoder technology employing a multiturn absolute encoder turn type and a high-resolution encoder resolution of 128 signal periods. Communication is facilitated via the industry-standard Hiperface encoder interface, enabling seamless integration with Rexroth drives and controllers. Designed for synergy with the MSK Series ecosystem, this servomotor offers stable performance in diverse automation applications such as robotics, packaging, and assembly. Compact, reliable, and designed for high torque density, it is an ideal choice for systems requiring accurate positioning and regenerative braking capabilities.

Frequently Asked Questions
Why choose a multiturn optical Hiperface encoder (128 signal periods) on MSK100A-0200-NN-M1-BP0-NNNN?
Its multiturn absolute sensing preserves position across power cycles and many revolutions for avoiding homing. It Hiperface interface with 128 periods integrates readily with Rexroth IndraDrive controllers and provides fine interpolation for accurate positioning.
How does natural-convection cooling on MSK100A-0200-NN-M1-BP0-NNNN influence continuous torque and noise?
The motor delivers 17.0 Nm continuous at 100 K for remaining quiet since no fan is used. If higher continuous torque is needed than its surface-cooled variants (Mo,S up to 22.5 Nm) are available in the family.
What practical benefit does the B-side power connector bring on MSK100A-0200-NN-M1-BP0-NNNN?
Its B-side exit eases cable routing in tight cabinets and keeps encoder and power leads segregated for aiding EMC practices. It also improves serviceability when the machine’s mechanical layout favors rear or side entry.
What environmental and thermal classes apply to MSK100A-0200-NN-M1-BP0-NNNN, and how do they affect installation?
The series specifies IP65 for shaft and housing and insulation class 155 (F) for enabling installation in dusty industrial spaces with appropriate seals. Its allowable ambient temperature and cable glands to maintain the protection rating is important to notice.
How do the 4 pole pairs and ~0.011 kg·m² rotor inertia in the MSK100A family influence servo response?
Its four pole pairs yield electrical frequency and back-EMF constants suitable for standard 400 V-class drives. Its rotor inertia guides gain scheduling and acceleration limits to avoid resonance while meeting step-response targets.
