The Bosch Rexroth Indramat MKD115C-024-KG1-AA from the MKD Synchronous Motors series by Bosch Rexroth Indramat features a rated power of 9.5 kW and operates on a 560V AC supply. It delivers a characteristic motor speed of 2000 rpm while achieving a maximum speed of 9000 rpm, enabling high-dynamic acceleration and deceleration profiles. Certified to IP65 protection class and Insulation class F, this servo motor withstands washdown conditions and resists ingress of dust and liquids. With a mass of 55 kg and a compact motor length C housing, the MKD115C-024-KG1-AA streamlines integration into space-constrained drive cabinets without compromising performance.

As a precision servo motor, the MKD115C incorporates a plain shaft design enhanced by a continuous shaft seal that prevents contaminants from reaching critical bearings. A robust holding brake with size dependent torque provides reliable axial locking during power-off states, securing loads without external brakes. Position feedback is delivered via a resolver feedback with integrated encoder, offering high-resolution data for closed-loop control over multiple revolutions. Standardized on a side A connection direction and identified by winding code 024, this motor ensures consistent mechanical and electrical interfaces across the MKD family.

Despite its substantial power output, the MKD115C-024-KG1-AA maintains a weight of 23 kg and natural convection cooling, eliminating the need for forced-air systems and reducing acoustic emissions. The protection category IP65 rating and rugged F-class insulation support long-term operation in demanding manufacturing environments. This combination of high torque density, compact dimensions, and advanced feedback makes the MKD115C-024-KG1-AA ideal for precision robotics, packaging machinery, and dynamic motion-control applications.

Frequently Asked Questions

Why use a plain shaft with a continuous shaft-sealing ring on MKD115C-024-KG1-AA, and what bearing-protection mechanism results?

The plain output shaft minimizes keyway stress concentrators, while the sealing ring blocks coolant and particulate migration toward the bearing set. It preserves bearing grease life and maintain axial/radial accuracy in contaminated environments.

What is the holding-brake role on MKD115C-024-KG1-AA—dynamic braking or static load-holding?

The integral brake (≈22 Nm per vendor listing) is specified for static holding at standstill and power-off axial locking, not continuous dynamic deceleration. It secures vertical axes and indexers when torque production is removed.

How should natural-convection cooling and insulation class F be considered when housing MKD115C-024-KG1-AA in sealed cabinets?

The surface-cooled MKD units rely on case-to-ambient heat rejection; cabinet airflow or heat-exchanger assistance may be required to avoid thermal limiting. Its class-F insulation adds thermal headroom but doesn’t replace proper enclosure temperature management and drive derating.

How do side-A power-connector orientation and resolver/feedback routing on MKD115C-024-KG1-AA influence harness layout and EMC inside crowded cabinets?

The side-A power exit fixes bend radii and strain-relief direction for simplifying parallel bus routing and reducing loop area. Its feedback cabling segregates from power runs to minimize capacitive/inductive coupling and encoder-channel noise.

How does 9.5 kW rated power, 2000 rpm characteristic speed, and ~55 kg mass of MKD115C-024-KG1-AA guide inertia matching and coupling selection on gantry or indexing axes?

The motor’s electrical point favors mid-speed torque with moderate rotor inertia; coupling selection should target 3:1–10:1 reflected-inertia ratios and torsional stiffness compatible with resolver bandwidth to avoid oscillation.

Internal Product Review

The Bosch Rexroth’s MKD115C-024-KG1-AA servo motor consumes 9.5 kW of power to operates from a 560 V AC soyrce supply. It normal rotational speed is 2000 rpm and it comes in an IP65 housing. This unit possess F-class insulation and uses a plain shaft with sealing ring. It has a resolver-based multiturn feedback and a holding brake to enable precise, power-off positioning. Its natural-convection and side-A connection streamlines machine-tool, packaging and handling-line integration.
