High rotational speed increases friction in bearings and air resistance (windage), so cooling (via convection or forced air) must dissipate that heat to avoid exceeding insulation class limits or degrading lubricant in bearings. Also, torque drops off at higher RPM due to increased losses, so thermal derating curves are essential to maintain reliability over long duty cycles.

The centering diameter ensures that the motor aligns with mating components concentrically, reducing misalignment-induced vibration and bearing load. A cable connection on Side A with coupling unit influences how routing is done; tight cable bends, length, and connector quality affect signal integrity (especially for encoder/resolver signals) and ease of maintenance.

A standard housing and shorter length (length code A) generally reduce footprint and mass, making it easier in space-limited or lightweight robotic arms or lab automation. However, shorter motors may have lower continuous power capacity or less margin for overloading, so careful matching of torque/speed profile to task is necessary.

The resolver requires analog-to-digital conversion and possibly filtering (resolver-to-digital converters) which add latency and requires compatible drive electronics; the absolute encoder output also must be read correctly and synchronized. The controller must support both feedback channels (or at least accept their outputs) and be tuned for combined feedback to avoid oscillations or position error due to phase shifts.

Holding the motor at standstill under load means minimal airflow, so heat generated by copper losses (current draw) accumulates, risking insulation damage or overheating unless the motor housing and installation allow sufficient heat dissipation. Mechanically, constant torque at zero speed stresses bearings and shaft keying, so regular maintenance or design for bearing preload is important.
