What is the impact of side B cable connection with coupling unit on cabling layout, service accessibility, and maintenance?

Side B connection means cable exits from a non-front face, which can complicate cable routing or mounting in constrained enclosures. The coupling unit adds coupling tolerance but also an extra potential failure point, so ensure compatibility, cable strain relief, and easy access for replacement or inspections.

What are the trade-offs of having a 40 mm centering diameter in terms of mounting rigidity and footprint in compact systems?

A 40 mm centering diameter provides a good compromise between stiffness and compactness; large enough for stable mounting under torque but small enough to fit in tight spaces. However, smaller centering diameters may flex more under radial loads, affecting positioning accuracy and causing additional load on shaft bearings.

What controller requirements (drive resolution, current capability, thermal overload protection) must a drive provide to fully exploit this motor?

The drive must support resolver interface with sufficient resolution and update rate to maintain precision at high speed, be capable of delivering sufficient current during peak torque demands, and include thermal monitoring or overload protection since continuous torque at standstill generates heat. Also, the drive should accommodate the motor’s inductance and resistance to avoid overshoot or oscillation.

What does “continuous torque at standstill” of 0.33 Nm mean in terms of motor cooling and thermal management?

At standstill, delivering 0.33 Nm means the motor windings are generating heat without airflow from rotor motion, so adequate cooling (e.g. conduction to frame, forced air) or thermal sizing of duty cycles is essential to avoid overheating. In B2B systems, this sets limits on how long the motor can hold torque without motion before needing rest or external cooling.

How does the resolver feedback affect precision, noise, and mechanical robustness compared to encoder feedback?

A resolver is more robust in harsh environments (resistant to dust, vibration, temperature) but generally has lower resolution than high-end optical encoders, so it may produce larger position quantization error. Noise immunity is better for resolvers, which helps in industrial settings where EMI is present.
