Frequently Asked Questions
How does the 57.0 Nm continuous standstill torque on MDD115D-N-015-R2L-130GL0 translate to sizing margins for vertical axes?
Its designers can counter static loads and friction while keeping copper losses predictable during holding. It simplifies thermal modeling for Z-axes in machining centers or pick-and-place gantries.
Why is the 130 mm centering diameter significant for retrofit projects using MDD115D-N-015-R2L-130GL0?
The Ø130 mm register standardizes pilot fit for easing alignment to legacy Rexroth/Indramat gearheads and frames. It reduces concentricity error during swapping for minimizing runout and coupling preloads.
How does the “plain shaft with shaft seal” on product code MDD115D-N-015-R2L-130GL0 affect coupling choices and ingress protection?
The plain shaft supports backlash-free clamp or keyless couplings, while the shaft seal limits lubricant egress and dust ingress at the front end. It preserves bearing life in particulate-prone cells.
How does the 1500 min⁻¹ nominal speed of MDD115D-N-015-R2L-130GL0 map to mechanical transmission selection?
The nominal 1500 rpm favors direct drive on moderate-speed axes or pairing with 3–5:1 gear ratios for torque densification. It keeps motor within thermal envelope while meeting cycle-time targets.
What housing and cooling assumptions apply to the MDD115 size-115, length-D frame, and how should clearances be planned?
The standard housing supports surface cooling/natural convection, it is important to maintain ventilation paths and ambient limits when panel-mounting or shrouding the motor. Its proper clearances avoid thermal throttling and loss of continuous torque.
