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

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.

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.

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

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.
