MSK100B-0200-NN-M1-RP0-NNNN
MSK IndraDyn S Synchronous Motors
The Bosch Rexroth Indramat MSK100B-0200-NN-M1-RP0-NNNN synchronous servomotor from the MSK IndraDyn S Synchronous Motors series features a voltage constant of 129.5 V/min-1 at 20 °C and delivers a maximum torque of 102.0 Nm at speeds up to 4100 rpm. With a winding inductivity of 7,600 mH and a continuous torque of 33.0 Nm at 100 K using 17.3 A, it ensures precise performance. Designed in a compact Motor Size 100 and Motor Length B frame, the device employs natural convection cooling and an IP65-rated housing with a right-side power connector. The multiturn absolute Optical Hiperface encoder provides 128 signal periods resolution, while the shaft with keyway and 40 μm primary coating support demanding environments. At standstill, it generates 42 Nm torque at 22.1 A, with a maximum current of 66.2 A, all within a standard design without holding brake.

Frequently Asked Questions
What does the 129.5 V·min⁻¹ (at 20 °C) voltage constant imply for MSK100B-0200-NN-M1-RP0-NNNN during field-oriented control?
It defines back-EMF versus speed for guiding drive sizing and DC-bus margins to avoid overvoltage at 4100 rpm. Its Ke streamlines IndraDrive parameterization and helps choose regen handling, braking resistors and speed-loop bandwidth for stable torque production under transients.
How does the 7,600 mH winding inductivity influence current ripple and servo bandwidth?
The inductivity filters PWM current ripple for easing torque ripple and acoustic emissions while shaping current-loop crossover. Its drive tuning must compensate with appropriate Kp/Ki and switching frequency selection to maintain dynamic torque response without saturating at the 66.2 A peak.
What advantages does the optical multiturn Hiperface encoder (128 periods) provide versus single-turn options?
It preserves absolute position across power cycles and multi-revolution moves for eliminating homing sequences and minimizing collision risk. It 128-period Hiperface interface enhances interpolation quality for smooth velocity control and precise contouring on packaging, printing and machine-tool axes.
How should I interpret the continuous 33.0 Nm at 100 K (17.3 A) versus the 42 Nm at standstill (22.1 A) figures on MSK100B-0200-NN-M1-RP0-NNNN?
The 100 K rating reflects permissible temperature rise under thermal steady state, while the higher standstill value is achievable with increased current and shorter thermal time constants.
How does the IP65 rating of MSK100B-0200-NN-M1-RP0-NNNN affect enclosure and washdown strategies?
The IP65 protects against dust and low-pressure jets at the housing and output shaft for simplifying integration near process media. Still, seal wear, shaft runout and lubricant compatibility must be managed to avoid direct coolant exposure at the sealing point and verify varnish adhesion.
