Product Description:
The MKD041B-143-GG1-KN servo motor is built by Bosch Rexroth Indramat as part of the MKD Synchronous Motors series. It converts controlled electrical input into precise rotational motion for automated axes, positioning tables, and pick-and-place modules. By supplying tightly regulated torque and speed, the unit serves as the primary actuator in industrial automation cells that demand synchronous performance and repeatable cycle times. Its synchronous servo design also supports stable response during acceleration, deceleration, and rapid directional changes in coordinated machine motion.
Electrical connection is routed through a connection box mounted on Side B of the stator housing, which helps keep cable routing compact in enclosed machine spaces. At continuous standstill, the rotor can deliver 2.7 Nm of torque, indicating the load the axis may hold indefinitely without excessive heating. The mechanical interface uses an 82 mm square flange that matches common gearhead patterns and keeps alignment straightforward. The housing is sealed to IP65, which keeps out dust and resists low-pressure water jets. For real-time motion feedback, the motor relies on resolver feedback, which produces analog sine-cosine signals for closed-loop control across the full electrical revolution. This feedback method also supports stable signal transmission in industrial environments where electrical noise is present.
An integral holding brake supplies 2.2 Nm of static torque to lock the shaft whenever supply power is removed, providing secure holding on vertical or suspended loads. Positional accuracy is rated at ±8 angular minutes, which is suitable for assemblies that require moderate precision and repeatable alignment. The centering pilot measures 50 mm in diameter, allowing concentric seating on the mating machine face, and the shaft includes a seal to help limit lubricant escape and contaminant entry. Continuous operation is permitted in ambient air from 0 to 40 °C. Within this temperature range, the insulation system supports repeated duty cycles without requiring auxiliary cooling equipment.
