A 40 mm centering diameter ensures that the motor can be precisely located in standardized housings to minimize misalignment; this reduces bearing loads and vibration in high-speed operation. In practice, the mating flange must be machined or selected to tight tolerances so that runout is kept low, especially above ~6000-8000 min⁻¹.

A plain shaft provides maximum flexibility for custom attachments but offers no rigid second end support, so radial loads should be kept minimal and bearings carefully selected. Accessories mounted directly to the shaft must account for potential overhang and its effect on shaft bending and dynamic balancing.

The relatively low holding torque means the motor is adequate for light loads or requires external brakes/servo control to avoid drift under load when stopped; for heavier loads, mechanical holding devices or dyn­amic control are needed. Also, thermal rise at standstill must be considered, since the motor may heat without rotation, potentially degrading insulation over time.

At such high speeds, heat generation in windings and bearings increases, so bearings should be high-precision, possibly using lubrication appropriate for high rpm and ambient temperature. Also ensure any shaft seals or external covers allow for proper heat dissipation and avoid trapping hot air.

Resolver feedback is robust under harsh environments (vibration, temperature) and resists electrical noise; it gives good analog/absolute positional data but usually lower resolution than high-pulse encoders. For applications where fine motion (e.g. <0.01°) or high bandwidth is required, check the control loop tuning and possibly augment with external encoder if supported.
