Product Description:
The MKD041B-058-KP1-KN is a servo motor manufactured by Bosch Rexroth Indramat within the MKD Synchronous Motors series. The unit is intended for industrial automation axes that demand repeatable speed and position control, such as light gantries, indexing tables, and packaging machinery. As the electromechanical element in a drive system, it receives three-phase power from an Indramat drive, converts it to mechanical rotation, and returns encoder feedback for closed-loop regulation.
Its mechanical interface uses a centering diameter of 50 mm and an 82 mm square flange, allowing direct mounting to gearboxes or machine frames without additional adapters. Power and feedback enter through a connection box positioned on Side B of the housing, simplifying cable runs in cabinets where drives are mounted below the axis. At standstill, the motor can deliver 2.7 Nm of continuous torque, a level supported by the 058 winding and the Class F insulation system. The stator and enclosure are sealed to IP65, and a shaft seal helps prevent fluid ingress at the output end. Integrated resolver feedback supplies position data, and size code 041 with length code B keeps the overall length modest for tight machinery layouts.
A holding brake is fitted for vertical or indexing loads, and it clamps the shaft with 2.2 Nm of torque when power is removed. During motion commands, control accuracy is supported by a system precision of ±8 angular minutes, and absolute position detection spans more than 4096 revolutions. The unit operates at ambient temperatures between 0–40 °C without derating, matching the thermal limits of its insulation. A shaft with a keyway transfers torque to couplings or pulleys, while the feedback channel maintains a stable reference during dynamic reversals.
