Frequently Asked Questions

What is the practical implication of 38.0 Nm continuous torque at standstill on MKD112C-024-KP0-BN for vertical or index axes without a holding brake?

The drive can command steady electromagnetic torque at zero speed without thermal runaway under rated cooling that enables precise dwell or clamping via closed loop.

How do the IP65 enclosure, keyed shaft, and shaft seal of MKD112C-024-KP0-BN mitigate contamination-induced runout or slip in packaging and printing environments?

The IP65 resists dust ingress and wash-down spray, while the seal reduces capillary lubricant loss and particulate intrusion at the journal. Its keyway establishes positive torque transmission to limit micro-slip that would otherwise degrade register or index accuracy in converting lines.

What mounting tolerances are driven by the 130 mm centering diameter and 192 mm flange on MKD112C-024-KP0-BN, and how do they affect coaxiality with precision gearheads?

The pilot diameter establishes radial location that maintain tight H7/h6 fits and face squareness to limit angular misalignment. Its correct pilot engagement reduces bearing side-load and ensures smooth backlash characteristics with DIN-compliant keyed couplings or adapter plates.

Why is natural-convection cooling acceptable for MKD112C-024-KP0-BN, and when should auxiliary airflow be introduced to arrest thermal droop during aggressive cycles?

The housing dissipates losses via surface convection and radiation without forced air, while under frequent start-stop or higher RMS torque demand, project planning guidance recommends blower assistance or derating to stabilize winding temperature and insulation life.

What benefits does resolver technology confer versus pure digital encoders on MKD112C-024-KP0-BN when subjected to vibration, electrical noise, or temperature excursions?

The resolver provide analog sine/cosine signals tolerant of EMI and high temperatures, with integrated multi-turn absolute tracking in this series. Its resulting commutation and position feedback remain stable under mechanical shock or cabling noise typical of heavy automation.

Internal Product Review

The Bosch Rexroth’s MKD112C-024-KP0-BN motor delivers 38 Nm at standstill and uses 10 A nominal current. It is housed in an IP65 frame and it possess a keyed shaft with an imposed seal for maximum protection. This unit has a resolver absolute feedback system of 4096 rounds for accurate positioning. It uses natural-convection for maintaining ambient temperature and its applications are usually in packaging, printing and in food processing lines.
