Product Description:
The MKD041B-143-GP0-KN belongs to the MKD Synchronous Motors series from Bosch Rexroth Indramat. As a servo motor, it is used in drive systems that require coordinated positioning, speed regulation, and repeatable cycle times in automated machinery. Its design supports relative position detection so the controller can monitor incremental movement and correct errors in real time, making the unit suitable for pick-and-place axes, compact gantries, and small tool heads. That control behavior is useful on axes that reverse often or operate with short, repeated motion segments.
The motor supplies a continuous standstill torque of 2.7 Nm, allowing it to hold or slowly index loads without overheating. A mounting flange of 82 mm provides a standardized face for coupling to gearboxes or machine frames, and the housing is sealed to IP65 to help protect the internal windings and bearings from dust and low-pressure water jets. Operation is permitted at ambient temperatures of 0–40 °C, and closed-loop performance is supported by a system precision of ±8 angular minutes. The flange size also helps the motor fit common small-axis mounting patterns. Winding code 143 identifies the electrical characteristics matched to the designated inverter, while motor length B and size 041 keep mass and inertia low for rapid acceleration.
A centering diameter of 50 mm aligns the motor concentrically with the gearbox pilot, and the connection box faces Side B for orderly cable routing. The integrated Resolver feedback device provides analog sine-cosine signals that remain stable near switching drives, and torque is transferred through a shaft with keyway. The connection box arrangement keeps the cable exit on one side of the housing, which can simplify routing in cramped installations. The motor is supplied without a holding brake, so load holding must be provided externally. The shaft seal helps protect the bearing area, and the class F insulation supports normal thermal loading in compact automation cells.
