What does the “continuous torque at standstill = 0.33 Nm” mean for dynamic performance?

It means the motor can hold 0.33 Nm without moving at zero speed without overheating; dynamic or starting torque will often be higher but limited by drive current and thermal constraints. In applications needing frequent starts or stopping under load (e.g. robotics), make sure the drive can supply greater peak current and that design accounts for inertia.

How does the nominal speed of 10,000 min⁻¹ affect gearbox or coupling selection?

At such high speed, any coupling or gearbox must handle high RPM with minimal imbalance, low backlash, and sufficient lubrication to avoid resonance or mechanical fatigue. Also ensures that bearing life is reduced unless load, vibration, and radial/axial shaft forces are well controlled.

What are the implications of resolver feedback for control precision and reliability?

Resolvers are highly robust in harsh environments (temperature, vibration, EMI) and don’t need optical alignment or lenses, but their angular resolution is lower than high-end digital optical encoders (≈ ±7 angular minutes for many MDD models with resolver feedback). So in ultra-high precision servo loops you may experience more positioning error or longer settling times compared to using an absolute encoder.

How does the shaft seal with plain shaft affect protection and mounting in dirty/wet environments?

The shaft seal increases ingress protection (up to around IP 65 in many MDD models) protecting against water jets and foreign particles along the shaft; plain shaft designs allow use of clamping hubs or pulleys but stress the bearing on the shaft end. Ensure seal choice and plain shaft coupling do not transmit radial or axial loads that exceed specified limits.

What are the mechanical mounting constraints given the 40 mm centering (pilot) diameter?

The 40 mm centering diameter (pilot) ensures compatibility with standard flanges of size MDD 025; precise machining of the mating flange surface is required to maintain concentricity. Misalignment or poor pilot fit leads to increased vibration, bearing loads, and possible early failure.
