Frequently Asked Questions
How is the 60 Nm blocking brake on MDD115D-N-015-N2L-130GA2 typically used in vertical axes or safety holds?
The brake holds the load when power is removed or during E-stops for preventing back-drive. Its blocking brake is rated at 60 Nm for secure holding during standstill.
Why does the 130 mm centering diameter on MDD115D-N-015-N2L-130GA2 matter for machine alignment?
The centering fit defines the mechanical datum for minimizing radial runout and easing coaxial alignment with gearboxes or couplings. Its consistent centering dimensions across the series simplify interchangeability and fixture design.
What does “57 Nm continuous torque at standstill” imply on MDD115D-N-015-N2L-130GA2?
It indicates the motor can deliver 57 Nm indefinitely at zero speed under rated thermal conditions without exceeding temperature limits. It is useful for static holding or tensioning applications requiring sustained torque.
How does the sealed plain shaft on MDD115D-N-015-N2L-130GA2 affect coupling choices and contamination control?
Its plain, keyed-less shaft broadens coupling options (clamp, friction, or shrink-fit). Its integrated shaft seal helps limit ingress of lubricants or particulates at the bearing journal during continuous duty.
How does MDD115D-N-015-N2L-130GA2 pair with Bosch Rexroth digital drive controllers in single-axis modules?
The DDC/DKS controllers support DSF feedback, commutation and diagnostics tailored to MDD motors. It can shorten feedback/power cable runs and reduce noise pickup in large plants.
