Frequently Asked Questions
With natural convection cooling, what mounting considerations affect continuous torque?
Mount the motor to a rigid, thermally conductive surface and allow free airflow around fins; inadequate heat sinking reduces continuous ratings. If duty cycle demands more cooling margin, the MSK101 accepts retrofit axial or radial fan units
Does the right-side power connector impact cabinet or cable routing?
Yes, plan motor orientation so the right-side exit avoids tight bends and keeps motor power separate from feedback to reduce EMC coupling. The MSK101 type code includes “R” for right-side connection to help specify this at design time.
What does the “shaft with keyway” imply for coupling and vibration?
A keyed shaft eases timing-critical couplings and simplifies torque transmission but requires proper key fit and full-key balancing to minimize runout. The MSK family supports keyed shafts per DIN 6885-1 and is balanced accordingly.
How should I interpret the “0300” winding code when pairing a drive and bus voltage?
Winding code selects back-EMF and current constants, affecting base speed and current demand at your DC bus (e.g., Rexroth data tables reference values at ~750 V). Match winding to the motion profile so the drive current limits and bus voltage headroom meet peak and continuous needs
What are best practices for inertia matching with a Size-101 rotor on high-throughput axes?
Keep reflected load inertia near the motor’s rotor inertia (often within 1:1 to 5:1 depending on servo bandwidth), and use coupling/compliance to damp resonances. Verify with your drive’s autotune and notch filters, then validate by step-response and frequency-response tests.
