What kind of current ripple or torque pulsation can I expect at 4000 min⁻¹ with this motor?

Due to synchronous operation with digital servo feedback, current ripple and torque ripple are minimized as the controller compensates for harmonics; residual ripple depends mostly on drive resolution and filter bandwidth. In practice, high-quality digital drives keep torque ripple below a few percent of nominal torque.

How does the 130 mm centering diameter affect mounting stiffness and alignment tolerance?

A larger centering diameter raises the bending stiffness of the coupling interface and reduces sensitivity to misalignment; you can tolerate slightly higher radial and angular offset without inducing excessive bearing loads. It also improves load distribution across the bearing housing and helps with dynamic stability at high shaft speeds.

How should I size the cable and connector given its nominal speed and digital servo feedback?

Because digital servo feedback demands low-latency and low-noise signals, use shielded twisted-pair or shielded multi-pair cables per Rexroth guidelines, and size power conductors so that voltage drop is <5 % at peak current. Keep cable runs short and route power and feedback separately to minimize EMI coupling.

Which dynamic loads (axial, radial, or torsional) should I particularly limit in a CNC or robotic application using this motor?

The motor bearings are typically optimized for radial loads; axial loads should be kept minimal (e.g. via thrust bearings or external supports) to avoid degrading bearing life. Torsional loads beyond the rated torque could lead to rotor demagnetization or stress in the shaft—so avoid torque spikes beyond ~1.5–2× continuous during acceleration.

What is the effect of ambient temperature or altitude on performance and cooling?

In high ambient temperatures or elevated altitudes (lower air density), natural convection cooling is less effective, which will reduce continuous torque capability before reaching thermal limits. For such environments, forced-air or external cooling may be required to maintain performance.
