It integrates seamlessly into Rexroth’s modular automation ecosystem, compatible with a wide range of drives, HMIs, and programming software. For engineers designing mid-sized systems, the REXROTHMKD041B-144-KG1-KN provides a balanced combination of power, precision, and adaptability, ensuring it can meet the demands of diverse industrial applications.

MKD041B-144-KG1-KN

Main features and advantages:

The REXROTH MKD041B-144-KG1-KN stands out for its exceptional balance of power and responsiveness. With a rated torque of 2.8 Nm, it can handle moderate loads with ease, making it perfect for applications like conveyor belt drives that need to maintain consistent speed while accommodating varying product weights. Its optimized rotor design allows for quick response times, enabling precise positioning in tasks such as automated screw driving, where accuracy within fractions of a millimeter is crucial to avoid damaging workpieces.

In terms of hardware, the motor features a rugged cast aluminum housing that offers durability without excessive weight, tipping the scales at 5.2 kg. It operates reliably in temperatures ranging from 0°C to 40°C (with derating up to 60°C) and boasts an IP65 protection rating, making it suitable for use in environments with light dust or moisture, such as food processing auxiliary equipment or automotive component assembly lines. The integrated multi-turn encoder provides detailed position feedback, ensuring that even repeated movements over extended cycles maintain consistent accuracy—essential for batch production where uniformity across products is key.

Compatibility is another strong suit of the REXROTH MKD041B-144-KG1-KN. It integrates smoothly with Rexroth’s IndraDrive Cs and IndraDrive Mi controllers, supporting communication protocols like PROFINET and CANopen for seamless integration into modern Industry 4.0 systems. This flexibility allows it to work alongside other components in the MKD series, as well as larger motors like the MHD115C-058-PG1-BA, creating scalable solutions that can adapt to changing production needs.

MKD041B-144-KG1-KN

Application areas:

In the realm of mid-sized industrial automation, where precision meets moderate power demands, the need for a reliable servo motor that can handle diverse tasks is paramount. Consider the packaging industry, where filling machines require consistent torque to handle varying container sizes while maintaining precise fill levels. In the textile sector, winding machines depend on accurate speed control to ensure uniform thread tension, preventing snags and material waste. Even in automated guided vehicle (AGV) systems, motors must deliver smooth acceleration and deceleration to navigate factory floors safely while carrying payloads. This is where the REXROTH MKD041B-144-KG1-KN excels. Used in industrial automation across these sectors, it bridges the gap between compact precision and robust performance, making it a versatile choice for applications that require more power than micro-motors but don’t need the full capacity of large industrial motors. Whether integrated into material handling systems or automated assembly stations, the REXROTH MKD041B-144-KG1-KN ensures consistent, reliable operation in the heart of mid-scale manufacturing processes.

Installation and maintenance:

Before installing the REXROTH MKD041B-144-KG1-KN, ensure the mounting surface can support its 5.2 kg weight without vibration, as uneven mounting can lead to premature bearing failure. Alignment with the driven load is critical; use a laser alignment tool to ensure concentricity within 0.1 mm, reducing shaft stress during operation. The motor’s IP65 rating allows for use in damp environments, but verify that cable entries are properly sealed with compatible glands to maintain protection. For systems with multiple motors, route encoder cables separately from power cables to minimize electromagnetic interference, which can affect position accuracy.

Maintenance for the REXROTH MKD041B-144-KG1-KN focuses on preserving its performance over extended cycles. Conduct monthly visual inspections to check for loose connections or signs of overheating, such as discolored wiring. The motor’s bearings are lifetime-lubricated, but if unusual noise occurs, inspect for misalignment or excessive load. Verify encoder functionality quarterly using the drive’s diagnostic tools to ensure position feedback remains accurate. Clean the motor’s exterior with a dry cloth; avoid high-pressure water or chemical cleaners, as they can damage the housing’s protective coating and compromise the IP65 rating.
