Frequently Asked Questions
How does the plain shaft with shaft seal affect coupling to other equipment?
The shaft seal protects against ingress of dirt and fluids, so mating components need to respect sealing surfaces and tolerances. Also, alignment precision matters more since there is no keyway to absorb minor misalignments.
In what situations would the lack of a blocking brake be problematic?
Without a holding brake, the motor cannot resist load torque when unpowered, which is risky in vertical or inclined loads. An external brake or mechanical lock would be required for safe holding in such applications.
How does the 95 mm centering diameter influence mounting precision?
It enforces exact centering on the mounting hub or flange, minimizing radial run-out and vibration under high speed. Poor matching leads to imbalance and shortened bearing life.
How does the digital servo feedback (DSF) shape control loop design?
DSF provides fast, precise digital feedback, allowing high bandwidth control and tighter error tolerances. Controllers must be compatible with the feedback format and ensure low latency to make full use of it.
How important is inertia matching for this motor’s application?
Matching the motor’s inertia to the load inertia (aiming for ratios like 1:1 to ~10:1) reduces overshoot and improves dynamic response. If the load inertia is far higher, acceleration will suffer and stability in motion control degrades.
