How does the 57 Nm continuous torque rating translate to industrial motion tasks?

It means the motor can sustain ~57 Nm indefinitely (at rated current) under proper cooling. That suffices for many CNC or robot axes where intermittent peaks fall within its 160 Nm capability.

What drive current capability is needed to realize the full 160 Nm torque?

The motor requires up to 137.7 A peak current to achieve 160 Nm output. Your servo amplifier must support that current headroom with minimal voltage drop.

In what scenarios would the shaft keyway design affect coupling to load?

The shaft-with-keyway supports high torque loads and resists torsional slip, making it ideal for gearboxes or direct-drive setups. But ensure key tolerances and alignment minimize stress concentration.

How can thermal sensors (e.g. KTY84) be leveraged in system control?

You can integrate the KTY84 output into your drive logic to monitor motor winding temperature in real time. This enables dynamic derating under overheating conditions before catastrophic failure.

How does the optical Hiperface singleturn encoder affect startup routines?

The encoder provides absolute reference immediately on power-up, eliminating the need for homing routines. That reduces machine initialization time, especially in multi-axis systems.
