MKD041B-058-KP1-KN

The Bosch Rexroth Indramat MKD041B-058-KP1-KN synchronous motor from the MKD Synchronous Motors Series provides a high-performance solution for precision motion control with an integrated shaft featuring a Shaft with keyway for secure torque transfer. This motor employs Natural Convection cooling, eliminating the need for external fans or liquid cooling circuits, and supports both Resolver feedback w/ integrated encoder and Absolute (>4096 revs) position detection for reliable feedback. Built to IP65 protection category, the unit resists dust and water intrusion while maintaining High Operational Reliability in challenging industrial conditions. The compact flange design simplifies installation and aligns with standard machine interfaces, making the MKD041B-058-KP1-KN an ideal choice for automated production systems requiring robust servo performance.

The technical specifications of the MKD041B-058-KP1-KN include a Continuous Torque at Standstill: 2.7 Nm and a Peak Torque: Wide Range capability for dynamic acceleration requirements. Mechanical dimensions are defined by a Centering diameter: 50 mm and Motor Size: 041, with a Winding Code: 058 indicating the optimized coil configuration. The integrated Holding Brake provides a Holding Brake Torque: 2.2 Nm to secure the shaft when stationary, and a Shaft Seal: Yes prevents contaminants from entering the bearing assembly. The motor connects via a dedicated Connection box, ensuring standardized cabling and simple field wiring. Mounting is achieved through a Flange Mounting interface, compatible with common machine tool and robotics platforms.

Operational performance is enhanced by a rated current of Rated current: 2.8 A at a winding temperature threshold of 100 K overtemperature, delivering a Rated power: 0.54 kW continuous output. Under peak demand, the motor can handle a Maximum current: 34 A and achieve a Maximum speed: 7500 min-1, giving it ample headroom for high-speed applications. The resolver-based encoder feedback and multiturn absolute encoder eliminate the need for homing cycles on power-up, improving system availability. The integrated shaft key complies with DIN 6885-1 standards, ensuring precise coupling to downstream mechanical components. Built for environments with mild vibration and moderate humidity, the motor’s robust design supports continuous operation in diverse industrial settings.

System integration of the MKD041B-058-KP1-KN is straightforward when paired with Bosch Rexroth servo drives, enabling advanced features such as auto-tuning and torque ripple compensation. The motor’s standardized flange and connection box reduce commissioning time and simplify retrofit projects. Target applications include robotic manipulators, packaging machines, CNC axes, and any automated process requiring precise torque control and high reliability.
