What is the significance of the winding inductance being 3,200 mH for system design?

A high inductance helps filter current ripples and reduce switching noise, but also slows the current change rate (dI/dt), which must be balanced by the drive’s current control bandwidth. In aggressive motion profiles, too much inductance can limit how fast torque can respond, so the drive must be tuned accordingly.

What is the thermal time constant and why is it important for duty cycle planning?

The thermal time constant is 100 minutes for this motor, meaning the motor requires that duration to reach ~63 % of final temperature under step power

How does the motor’s design facilitate coupling to gearboxes, and what coupling precautions should I take?

The plain (smooth) shaft allows flexible mounting via clamping sets, sleeves or keyed couplings, but you must ensure proper centering and torque transmission without introducing excessive axial or radial loads

What are the bearings’ expected lifetime under typical industrial radial/axial loads?

If operating within the specified radial and axial limits and maintaining mean speeds per the grease lifetime curves, the L10h bearing life is 30,000 h by ISO 281 standards

What resolution and accuracy trade-offs come from the EnDat 2.1 encoder with 2048 signal periods?

2048 signal periods (per revolution) in combination with multiturn capability gives precise absolute positioning with a resolution of about 2000 steps per rev. But mechanical backlash, cable length, and interpolation errors in the drive may still dominate real-world accuracy.
