Product Description:
The MKD112B-073-KG1-AN belongs to the MKD Synchronous Motors series produced by Bosch Rexroth Indramat. As a servo motor for industrial automation, it converts regulated AC power into precise rotary motion so that positioning axes, gantries, or transfer stations can follow programmed speed and torque commands. It is intended for closed-loop motion tasks where stable response and repeatable positioning are required throughout automatic machine cycles. This makes it suitable for machine sections that depend on accurate speed regulation during indexing, feeding, and synchronized transfer movements.
The motor body is guided into the machine frame by a centering recess of 130 mm, while a 192 mm square flange carries the mounting bolts that secure the stator housing. Power and feedback conductors exit on Side A; this fixed connection direction simplifies cable routing in cabinets that share a common service corridor. An output connector carries the phase lines and protective earth. When energized, the motor can provide 28.0 Nm of continuous torque at standstill, a rating used for thermal sizing of the inverter and any external cooling. Inside the housing, a resolver-based sensor provides resolver feedback, allowing the control loop to calculate instantaneous rotor position even during rapid accelerations. The physical envelope is identified as length code B and size 112, so retrofit designs can compare stack height and magnetic capacity against other MKD units.
A factory-installed holding brake supplies 22 Nm of static torque to maintain axis position when mains power is removed. Coupled with the encoder's absolute (>4096 revs) capability, the axis can recover its coordinates immediately after a restart without homing routines. A plain shaft transfers torque to couplings or gearboxes, and a shaft seal helps prevent lubricant migration along the journal in enclosed machine sections. This combination supports controlled motion and secure standstill behavior in automated equipment.
