Product Description:
The MKD041B-144-GP1-KN is a servo motor produced by Bosch Rexroth Indramat within the MKD Synchronous Motors series. As a compact drive element for industrial automation, it delivers closed-loop torque and speed control to axes on packaging lines, handling robots, and CNC equipment. The motor integrates seamlessly with Rexroth digital drive controllers, providing the response profile required for precise positioning tasks in multi-axis assemblies.
This model supplies a continuous standstill torque of 2.7 Nm, allowing it to hold load without overheating during static phases. Mechanical interfacing is based on an 82 mm square mounting flange, and centering is achieved through a 50 mm pilot to maintain concentric alignment. Power is transmitted through a shaft with keyway, so couplings can lock axially without slip. Rotor position is monitored by a resolver feedback (RSF) unit, and the feedback scheme works with relative position detection rather than absolute scaling. The motor is designated Size 041 and Length B, a geometry that limits overall mass while still accommodating the internal winding set and magnetic circuit.
For dynamic stops during power loss, the brake can exert 2.2 Nm of holding torque on the shaft. Cables exit on Side B, a layout that simplifies routing when the motor is installed deep inside machinery. Termination occurs in a sealed connection box, protecting signal pairs and power leads from oil splash and metal chips. The stator is wound to pattern 144, matching it electrically to MKD drives that supply the correct current profile. An internal resolver manages relative position data, and the connection architecture is completed by the motor’s RSF channel, its B-length housing, and the keyed shaft interface, forming a package intended for repetitive indexing and mid-range torque duties.
