Product Description:
The MKD041B-143-KG0-KN is a servo motor in the MKD Synchronous Motors series from Bosch Rexroth Indramat. In automated production cells, the unit delivers coordinated rotary motion to positioning stages, feed drives, and packaging spindles where closed-loop speed and position control are required. Its 041 size with the B length keeps the housing compact, which helps the motor fit into space-limited axis arrangements. This makes it suitable for equipment that needs accurate motion in confined machine layouts.
The motor uses an 82 mm flange for direct front mounting on compact gearboxes and machine plates. A 50 mm centering pilot aligns the stator concentrically on the machine frame and helps limit radial runout. At standstill, the drive can exert 2.7 Nm continuously, so small axes can hold steady loads without overheating. All power and feedback conductors exit on side B and terminate in a sealed connection box that simplifies wiring. The housing has an IP65 rating to resist dust and low-pressure water jets, and the motor uses insulation class F for thermal endurance. The sealed box also helps protect the cable entry point during routine washdown cleaning. Because the design is supplied without a holding brake, any required static locking must be provided externally.
Motion feedback is supplied by resolver feedback with an integrated encoder, and absolute tracking beyond 4096 revolutions supports repeatable startup positioning. Mechanical accuracy is characterized by a system precision of ±8 angular minutes, which helps reduce cumulative error in multi-axis assemblies. The motor has a plain output shaft with a positive shaft seal, which removes keyways that can contribute to micromotion at the coupling. Reliable operation is specified from 0–40 °C, matching typical enclosed machine conditions. The shaft seal also helps keep contaminants away from internal bearings during normal machine operation. Internal copper geometry follows winding code 143 to match the current ratings expected by compatible MKD drives.
