How significant is the 11 Nm holding (blocking) brake in system integration?

The holding brake allows the axis to lock when deenergized, which simplifies safety or power-off holds without external brakes. But the brake coil draw and release timing must be considered in the drive logic and control sequence.

What is the practical speed-torque tradeoff when running close to 3000 min⁻¹?

As speed increases, back-EMF rises, reducing available torque margin, so you’ll get less usable torque near nominal speed. Also, voltage and current limits of the drive may further restrict torque at high speed, so lookup the torque curve in drive-motor pairing.

How do shaft sealing and keyway design influence maintenance and reliability?

Shaft seals protect internal components from contamination and improve lifespan in harsh environments, but require precise shaft tolerances to avoid friction. A keyway ensures torque transmission under load spikes, but introduces stress concentrations, so fillet radii and edge chamfers matter in fatigue longevity.

What care is needed in drive selection to support the digital servo feedback interface?

You must use a drive controller compatible with Bosch Rexroth’s DSF (Digital Servo Feedback) protocol to read position, velocity, and commutation data. Incompatible drives may not initialize or may misinterpret encoder signals, resulting in erratic behavior or no motion.

How must the mounting screws and torque values be chosen for a 093 frame motor?

Bosch Rexroth specifies 4 × M10 screws with a tightening torque of 51 Nm for MHD/MDD 093 frame motors to hold the flange securely.
