MKD112C-024-KP3-BN
MKD Synchronous Motors
MKD112C-024-KP3-BN, Bosch Rexroth Indramat, MKD Synchronous Motors. The synchronous servo motor delivers a continuous torque of 36 Nm and supports a power range up to 4 kW within an ambient temperature of 0 to 40 °C. With a maximum speed of 6000 RPM and an IP65 protection rating, this motor excels in harsh industrial environments. Its Winding Code 024 ensures precise thermal characteristics during extended duty cycles.
Featuring a robust Shaft Design with keyway and integrated Shaft Seal, the unit withstands contamination and axial loads. An electromechanical Holding Brake provides 70 Nm holding torque, securing the axis when de-energized. The built-in Resolver feedback w/ integrated encoder offers absolute position detection over >4096 revolutions, paired with an Insulation Class F winding for elevated thermal endurance. The motor’s Centering diameter of 130 mm and overall Motor Length C facilitate straightforward integration into existing flanged assemblies.
Integration is simplified by the factory-mounted electric box with connectors, eliminating on-site terminal wiring. The combination of standard cooling, rugged enclosure, and high-resolution feedback guarantees reliable closed-loop control in servo drives. Ideal for machining centers, robotics, and packaging lines, the MKD112C-024-KP3-BN delivers consistent performance, easy commissioning, and peak uptime in demanding automation applications.

Frequently Asked Questions
Why specify a keyed output shaft with an integrated shaft seal in this code variant?
The keyway provides positive torque transmission and repeatable phasing for couplings and pulleys, while the seal mitigates ingress that accelerates bearing and resolver wear. It tolerates axial/radial loads in coolant- or dust-laden cells typical of machine tools and packaging machines.
What control advantages arise from resolver-based absolute position detection (>4096 revs) compared with incremental feedback?
The resolver supply sine/cosine vectors tolerant to EMC and temperature for enabling deterministic commutation at startup without homing. Its absolute multi-turn data preserves position after power loss that shrinks cycle recovery time and improves closed-loop stiffness in multi-axis kinematics.
How does the 70 Nm holding brake option affect vertical-axis safety and servo tuning?
The brake secures the drivetrain when de-energized for reducing back-drive on Z-axes and gantries. Its 70 Nm static torque allows lower standby current and softer detune of position loops during e-stop scenarios without load drop.
How does Centering Ø 130 mm with Motor Length “C” simplify retrofit into legacy flanged assemblies?
The 130 mm pilot controls run-out and shear loading to ease concentric alignment with gearboxes or belt stages. It keeps stack length predictable to preserving shaft overhang factors and simplifies spacer/bell-housing reuse.
Why is Insulation Class F significant for MKD112C-024-KP3-BN in extended duty cycles at 0–40 °C?
The class F materials tolerate higher winding hot-spot temperatures for enabling sustained torque without premature varnish breakdown. It extends bearing grease life indirectly by limiting heat soak into the end-shields during prolonged S1 operation.
