MKD071B-061-EG0-KN

The MKD071B-061-EG0-KN is a servo motor produced by Bosch Rexroth Indramat within the MKD Synchronous Motors series. It is used in automation cells to deliver commanded torque and speed to conveyors, actuators, or tooling spindles under closed-loop control from a Rexroth drive. The motor mounts to the machine frame through a 115 mm square flange and is centered by a 95 mm pilot, giving installers an easy way to align the rotor with coupled loads. Because the unit is supplied without a holding brake, external locking or continuous drive excitation must be employed to maintain position during power-off states.

Mechanical interface details support flexible wiring and repeatable assembly. Power and feedback conductors exit on Side B, and the terminations are housed in a sealed connection box, so cable glands can be fitted without exposing internal windings. The flange dimension of 115 mm matches common gearbox and actuator patterns, while the centering diameter of 95 mm ensures concentric alignment that minimizes radial run-out. At standstill the motor can sustain a continuous torque of 8.0 Nm, allowing it to hold static loads or follow low-speed motion profiles without overheating. A plain front face is provided by the plain shaft configuration, eliminating key stresses associated with keyed assemblies. The shaft seal present at the output end blocks lubricant migration and protects the interior against splash water or dust.

Internal characteristics further define drive selection. Winding code 061 specifies the stator copper pattern and associated electrical constants chosen for medium voltage inverters. Frame coding starts with motor size 071, a diameter class that balances inertia and peak speed for general-purpose machinery. The length designation B offers a moderate axial dimension and contributes to the 8.0 Nm continuous rating without requiring forced cooling. Together, these parameters let system engineers match the motor to gear ratios, duty cycles, and ambient conditions while relying on a factory-installed shaft seal for basic environmental protection.
