BOSCH REXROTH MKD071B-061-KP0-KN – Compact AC Servo Motor for Fast, Repeatable Positioning

The Bosch Rexroth (Indramat) MKD071B-061-KP0-KN is a proven synchronous AC servo motor built for high-speed, high-precision axes. From my experience, this size 071, B-length motor fits nicely on mid-range feed drives and pick-and-place axes where quick acceleration and smooth velocity control matter. The “061” winding typically corresponds to a high-speed class (often used around 6,000 rpm applications), while the “K…N” tail signals a keyed shaft and standard sealing configuration. You might notice how easily it drops into existing DIAX04/DDS or EcoDrive (DKC) systems—most retrofits take less time than expected if the cabling set is on hand.

Key Features

• High-speed MKD platform – The 071 frame with “061” winding is commonly used in fast positioning axes and continuous-duty feed drives where tight speed loop control is needed.
• Precision feedback for closed-loop control – MKD motors are equipped with Rexroth’s integrated servo feedback and thermal sensing for reliable commutation and accurate speed/position regulation.
• Keyed shaft, standard sealing – “K…N” indicates a shaft with keyway (DIN-style) and standard sealing, simplifying coupling alignment and torque transfer.
• Rugged build, IP65 front – Typically supplied with high ingress protection at the shaft/flange and insulation class F; suitable for industrial cabinets and machine frames.
• Drive compatibility – Works with Bosch Rexroth DIAX04 (DDS) and EcoDrive (DKC) controllers; many users also migrate to newer IndraDrive with the correct feedback interface and cables.
• Low maintenance – No brushes, sealed bearings, and temperature monitoring. In many cases, these run for years with only connector checks and periodic cleaning.
• Typical applications – Packaging infeed rollers, labeling heads, SMT conveyors, indexing tables, gantry Y/Z axes, and printing line feeds where repeatability and uptime drive output.

Technical Specifications

Related or Supporting Products

• MKD071B-061-GP0-KN – Similar mechanical size; “G” feedback variant. Often chosen when a different encoder interface is required by the installed drive.
• MKD071B-058-… – Same frame with alternate winding (lower base speed). Good when higher torque at lower speeds is preferred.
• MKD090B-… – Larger frame for higher torque axes. Useful when upgrading to heavier payloads.
• DDS02.1 / DDS03.1 servo drives (DIAX04) – Native pairing for MKD motors; straightforward parameter sets and connectors.
• DKC03.3 (EcoDrive 03) – Compact drive controller; many lines use this with MKD071 for packaging and handling machines.
• Power/feedback cable sets – Rexroth cable kits for MKD series (shielded motor power cable and encoder cable) reduce noise and commissioning time.

Installation & Maintenance

• Mounting & alignment – Use the B5 flange with proper dowel/centering. The keyed shaft simplifies coupling; check runout and alignment to minimize bearing load.
• Cabinet environment – Keep the drive in a ventilated control cabinet (IEC standards). Maintain clean air paths; avoid oil mist and conductive dust near motor connectors.
• Wiring – Use shielded motor power cables with correct PE bonding, and the listed Rexroth feedback cable. From my experience, good shielding solves 90% of nuisance encoder alarms.
• Thermal & loading – Respect permissible radial/axial loads and ambient limits. If the machine runs hot, consider airflow across the motor body or slight derating.
• Routine checks – Inspect connectors for tightness, clean vents and exterior, verify ground continuity. Run the drive’s autotune after mechanical changes to keep servo performance tight.
• Firmware & parameters – Keep the drive firmware within the revision Bosch Rexroth recommends for MKD motors. Back up parameter sets before any updates.

Quality & Certifications

• CE compliant; UL recognition and RoHS conformity are commonly available on MKD series motors.
• Manufactured to Bosch Rexroth quality standards; insulation class F, industrial-duty IP protection.
• Warranty: 365 days from our side, with fast replacement/repair handling in most cases.

One thing I appreciate is how forgiving the MKD071 is during commissioning—tuning usually lands quickly, and the keyed shaft makes coupling swaps easier. If you’re matching an installed drive, share your drive type and cable lengths and I’ll confirm feedback compatibility and exact motor data before you place the order.
