What is the impact of the 6.5 Nm holding (blocking) brake on system safety and positioning when power is removed?

The holding brake mechanically locks the shaft when power is removed, preventing movement under load; this is useful in applications requiring fail‐safe holding or emergency stops. However, brake release time and wear must be considered, and the system must supply enough energy (voltage/current) to engage/disengage reliably.

What cooling method does the motor employ, and how does it influence ambient temperature and duty cycle?

The motor is sealed with shaft seal and uses natural convection and surface cooling in standard housing design. High ambient temperatures or heavy continuous loading reduce cooling effectiveness, so one must derate torque or ensure enhanced ventilation in harsh conditions.

What speed ranges can be expected from the nominal speed of 3000 min⁻¹, and what factors limit speed beyond nominal?

Nominal 3000 min⁻¹ is the designed operating speed; pushing above increases centrifugal stress, bearing heating, and torque drop (due to back EMF and motor inductance). Cooling, rotor inertia, mechanical load balance, and drive capability are limiting factors for speed overshoot.

What maintenance or lifetime factors are influenced by “cannot be disassembled in the field” for Bosch Rexroth’s digital feedback motors?

Because the DSF feedback module and internal components are sealed and not serviceable, any damage or drift in the feedback encoders typically requires factory service or full replacement. Regular inspection of cable integrity, vibration, and operating environment is critical to avoid premature failures.

How does the product code (MDD090C-N-030-N2L-130GA1) by Bosch Rexroth correlate with motor performance and configuration?

Each segment of the code identifies performance/hardware parameters: for example, “090” is the size class (which influences torque/inertia), “C” is the length code, “030” relates to winding and speed rating, “N2L” to feedback and mounting features, and “130GA1” to centering diameter, brake, shaft sealing, or configuration. Reading the code lets you verify compatibility with existing systems and choose correct matching motor variants
