MKD112B-073-KG0-BN

The MKD112B-073-KG0-BN is a servo motor produced by Bosch Rexroth Indramat for the MKD Synchronous Motors series. This model converts drive controller output into rotary motion for positioning, feed, and auxiliary axes in automated machinery. Integrated resolver electronics deliver electrical angle data to the drive so the motor can close the velocity or position loop in demanding industrial environments.

The housing centers on a 130 mm centering diameter, aligning the 192 mm flange precisely to gearboxes or machine frames; the flange’s 192 mm square pattern matches standard mechanical interfaces in this size class. At standstill the electromagnetic package delivers 28.0 Nm of continuous torque, allowing static load holding without overheating. Rotor position is monitored by a Resolver feedback unit that integrates an encoder for hybrid analog–digital reporting, enabling smooth commutation even during slow creep speeds. Power and feedback conductors exit on Side B, and an output connector simplifies removal because cables stay with the cabinet harness. Motor identification within the family is helped by the “112” size code and the “B” length code, both indicating mid-range inertia suitable for moderate acceleration profiles.

The drive shaft uses a Plain shaft design, eliminating keyway stress concentrations in coupling arrangements, and there is a shaft seal that limits lubricant migration into the stator cavity. Mechanical parking torque must be provided externally because the unit ships without a holding brake. Absolute feedback resolution of >4096 revs lets CNC or PLC systems resume motion sequences after power cycling without homing. Because the motor length is coded “B,” overall package depth remains compact for retrofits, while the output connector orientation maintains low enclosure depth. Position detection, centering geometry, and connector routing together support tight installation envelopes common on material-handling gantries and indexing tables.
