The Bosch Rexroth MPN R911342558 (MSK100A-0300-NN-M2-LG0-RNNN) is an IndraDyn S series synchronous servomotor designed for automation applications requiring precise control. It utilizes an optical, multiturn EnDat2.1 encoder with 2048 signal periods for accurate position feedback. The motor achieves a continuous torque of 15 Nm at 60 K and 17 Nm at 100 K, with a continuous current at standstill (100 K) of 11.6 A and a maximum current of 45.9 A. The maximum torque output is 54.0 Nm and top speed reaches 5200 rpm. The motor features natural convection cooling, a left-side power connector, plain output shaft with sealing ring, and increased concentricity design. It meets IP65 protection and thermal class 155, operates optimally between 0 and +40°C, and withstands transport from -20 to +80°C. The motor weighs 23 kg and produces less than 75 dB of noise during operation.

Frequently Asked Questions

How does the 11,200 mH winding inductance influence current ripple and EMC behavior in the MSK100A family?

The inductance moderates di/dt for reducing current ripple into the inverter and smoothing torque production. It helps with conducted emissions and allows current controllers to run stable with modest switching frequencies and typical cable lengths.

What benefits come from the “increased concentricity” and plain-shaft configuration on MSK100A-0300-NN-M2-LG0-RNNN?

The tighter rotor/runout tolerances minimize radial vibration for easing alignment with bellows or clamp couplings. Its plain shaft broadens coupling choices and simplifies assembly when backlash and compliance must be tightly controlled in precision axes.

How do the 17.0 Nm continuous @ 100 K and 54.0 Nm max torque ratings on MSK100A-0300-NN-M2-LG0-RNNN translate to motion profiles?

The continuous torque sets sustained feed forces without exceeding thermal limits, while 54 Nm accommodates bursts for acceleration, cornering or tool approach. Its drive parameterization should constrain duty cycles to avoid cumulative heating beyond the 100 K benchmark.

How does the left-side (LG0) power connector orientation on MSK100A-0300-NN-M2-LG0-RNNN aid cabinet and machine layout?

Its routing aligns cable exits with left-hand raceways in many gantries for reducing bend radii and strain at the motor head. It also helps segregate power from feedback harnesses to improve EMC margins.

Why choose natural-convection cooling on MSK100A-0300-NN-M2-LG0-RNNN for machine enclosures with acoustic limits?

The convection eliminates fans for reducing acoustic emissions and particulate ingress paths while simplifying maintenance. Its thermal design still supports significant continuous torque when paired with proper mounting surfaces and ambient derating in sealed cabinets.
