Product Description:

The MKD112D-027-KG0-AN belongs to the MKD Synchronous Motors series produced by Bosch Rexroth Indramat. It is a servo motor intended for closed-loop positioning and speed control on automated axes, where rapid response and repeatable motion are required for packaging lines, machine tools, and material-handling stages. Its synchronous design supports quick correction of load changes so the axis can maintain accurate motion during repeated starts, stops, and speed changes.

This model supplies a continuous standstill torque of 48.0 Nm, allowing the drive to hold loads without overheating during prolonged dwells. A centering diameter of 130 mm aligns the housing precisely with the mating machine bore, and the 192 mm flange provides the mounting pattern that secures the motor to the machine face. Rotor electrical characteristics correspond to winding code 027, so the paired drive must provide a matching current and voltage profile. The feedback system uses resolver feedback integrated into the end bell, and this analog device produces sine and cosine signals that give rotor position to the controller. Because the unit is supplied without a holding brake, any vertical load must be restrained by external mechanics or by drive torque during shutdown.

Cabling exits on side A, which can simplify panel layout when the motor is mounted close to the cabinet wall, and the power and feedback lines are consolidated in an output connector to reduce wiring errors. The shaft is a plain shaft, so torque is transmitted with a compression coupling rather than a keyed hub, which helps reduce stress concentrations during reversals. Position detection is absolute for more than 4096 revolutions, letting a multi-turn counter track the shaft through many turns without battery support. A shaft seal is included to limit lubricant leakage and protect the resolver cavity from coolant or dust ingress, and the D-length housing provides additional active material within the same frame family.
