MSK101C-0300-NN-M1-AP2-NNNN
MSK IndraDyn S Synchronous Motors
The Bosch Rexroth Indramat MSK101C-0300-NN-M1-AP2-NNNN from the MSK IndraDyn S Synchronous Motors series is a high-precision IndraDyn S Synchronous Servomotor featuring a motor size of 101 and length C. It delivers a continuous torque at standstill of 36.5 Nm (100 K) at 21.3 A and a maximum torque of 110.0 Nm with a maximum current of 84.2 A. The motor includes a with holding brake, electrically-released producing 70 Nm of brake torque and requires Cooling FN for thermal management via natural convection. It employs an optical encoder with multiturn absolute turns, an Hiperface interface and 128 signal periods resolution. The shaft with keyway and A-Side power connector ensure secure mechanical and electrical connections, while its standard design and 6,000 mH winding inductivity provide robust performance.

Frequently Asked Questions
How does the M1 optical multiturn Hiperface encoder in MSK101C-0300-NN-M1-AP2-NNNN improve servo loop stability and positioning repeatability?
It provides absolute multi-turn feedback with 128 signal periods for enabling precise commutation and immediate position availability after power-up to eliminate homing. Its Hiperface interface delivers deterministic communication with IndraDrive controls for crisp velocity and position control.
What are the thermal and duty-cycle implications of the “NN” natural-convection cooling on MSK101C-0300-NN-M1-AP2-NNNN?
Its self-cooling favors clean, low-airflow installations and reduces maintenance but continuous torque is bounded by ambient and mounting conditions. For higher continuous torque, consider surface/forced cooling variants.
Why is a keyed shaft specified, and how does it influence coupling design on this motor?
The shaft with keyway simplifies torque transmission into pulleys, synchronous belt drives or rigid couplings for minimizing slippage. It also aids angular indexing for cams or print registers, while allowing predictable shear-stress calculations during peak-torque transients.
What role does the 70 Nm electrically released holding brake play in vertical axes using MSK101C-0300-NN-M1-AP2-NNNN?
The spring-applied, power-off brake secures the load during e-stop or power loss and short maintenance interventions. It reduces Z-axis drift that streamlines safe maintenance and limits the need for external mechanical locks on moderate-inertia vertical mechanisms.
How do 21.3 A continuous current (100 K) and 6,000 mH winding inductivity affect current-loop tuning and EMC?
The higher inductance smooths ripple current for easing current-controller stability at moderate PWM frequencies and reducing motor-cable EMI. Its drive current-loop bandwidth should be matched to the motor’s electrical time constant to avoid overshoot during torque steps.
