Frequently Asked Questions
How should I interpret the 40 mm centering (pilot) diameter during mounting?
The pilot registers the motor concentrically to the machine flange; if it’s off, you’ll see runout and bearing load at 10 krpm. Treat the pilot as the primary datum and set shaft-to-coupling alignment from it
Any balancing notes relevant to high-speed operation and vibration?
Units are delivered in standard (Class N per DIN VDE 0530) balance, which is adequate for most couplings at 10 krpm when alignment is correct. Poor pilot fit or misaligned couplings will dominate vibration more than balance class.
What are realistic use cases where its small frame and 10 krpm help in B2B machinery?
Tight-space auxiliary axes in pick-and-place, screwdriving, and tool changers benefit from the slim MDD02x formats and high feed rates. Packaging, robotics, and tooling lines are common deployments.
How should I think about holding at standstill without a brake?
With 0.33 Nm continuous standstill torque you can maintain smaller loads using closed-loop current, but vertical axes should employ a brake or counterbalance. Relying on torque hold alone risks droop on power loss.
What environmental/installation steps extend life in CNC/semiconductor tools?
Use shock-damped mounts in high-vibration frames and respect IP65 sealing at connectors/shaft to keep abrasive fines and coolant out. Proper sealing and decoupling significantly reduce bearing wear and encoder faults.
