Product Description:

The MKD041B-144-GG1-KN is a servo motor produced by Bosch Rexroth Indramat and supplied within the MKD Synchronous Motors series. With a size code 041 and a length designation B, the motor fits compact machine axes while still providing the dynamic torque needed for packaging lines. It is delivered with an integrated holding brake so vertical or suspended loads can be secured when power is removed. Its feedback system supports relative position detection for coordinated multi-axis motion in assembly cells and handling gantries. Its compact frame also suits indexing stations and small transfer mechanisms where fast starts, stops, and accurate synchronization are required.

The motor has a centering diameter of 50 mm and a flange size of 82 mm, so it can mount to compact gearboxes or direct-coupled loads without additional adapters. Motor power and feedback conductors exit on side B through a sealed connection box, which helps keep cable routing organized. A shaft seal is fitted to limit the entry of lubricant or coolant along the output shaft. Under continuous stall conditions, the rotor can deliver 2.7 Nm of torque. Position signals are generated by resolver feedback, which provides noise-resistant analog sine-cosine outputs in electrically demanding environments.

The output end uses a plain shaft, which permits backlash-free clamping with couplings or pulleys. The shaft format also works well with clamp hubs that do not require a keyed connection. The integrated brake provides 2.2 Nm of static holding torque to help keep the axis from moving at standstill. Winding code 144 identifies the electrical design used for this motor and the values expected by a matching Indramat drive. This arrangement supports stable torque production and repeatable motion during continuous operation.
