Frequently Asked Questions
How critical is the centering diameter (110 mm) for coupling alignment and rigidity?
The centering bore ensures that the motor’s force is transmitted with minimal eccentricity; using a matching flange and rigid coupling minimizes misalignment, vibration, and bearing stress.
What are the trade-offs when using a plain shaft with shaft seal versus a keyed shaft?
A plain shaft with seal gives better radial runout and sealing against contaminants but requires clamping hubs or shrink fits, whereas keyed shafts simplify torque transfer but risk wear or backlash.
In what situations would the left-oriented connector be a constraint in system design?
In compact or tightly spaced systems, left connector orientation may clash with cable routing or adjacent axes; you must reserve clearance or use angled adapters.
How does the nominal speed (3000 min⁻¹) relate to the motor’s usable torque curve?
Up to nominal speed, the motor can deliver near its rated torque; beyond that, the torque typically drops off due to back-EMF limits, so design must respect speed limits.
What mechanical balancing is implied by the “Standard” balancing, and when might you require a higher grade?
“Standard” balancing meets industrial norms for mid-speed operation; for high-speed (≥5000 rpm) or ultra-precise applications (minimizing vibration), an enhanced balance grade may be needed.
