Product Description:
The MKD112B-024-KG1-BN is a servo motor built by Bosch Rexroth Indramat for the MKD Synchronous Motors series. As an electromechanical actuator, it converts drive current into controlled rotary motion, allowing CNC stations, packaging lines, or gantry axes to position loads with repeatable accuracy. Its integrated feedback and plain shaft design make it suited for closed-loop control tasks where speed and torque must track the command profile generated by the automation controller. This operating principle allows the motor to respond quickly to command changes during indexing, contouring, and synchronized axis movement. It is suited for applications that require repeatable starts, stops, and speed changes over frequent duty cycles.
At standstill, the motor can deliver 28.0 Nm of continuous torque, providing the baseline force for static holding or low-speed moves without overheating. A square 192 mm front flange mates directly to ISO gearboxes, while the 130 mm centering diameter aligns the housing with minimal runout. The flange and centering shoulder help maintain accurate alignment between the motor and the driven machine element. Power and feedback leads exit on side B, and the single output connector keeps cable routing compact. This connection layout can simplify cable management when the motor is mounted close to guarding or adjacent axes. The B length code balances thermal mass against footprint, and the size 112 frame provides adequate magnetic area for medium-duty axes. A plain shaft transmits torque through clamp or keyed couplings without additional interface parts.
When power is removed, an integrated brake supplies 22 Nm of holding torque, preventing drift on vertical or suspended loads. The brake supports load retention while the drive is disabled. Motion feedback comes from resolver feedback combined with an integrated encoder that supplies absolute position data over more than 4096 revolutions, eliminating homing cycles after power-up. This feedback arrangement helps the controller identify shaft position immediately after startup. Electrical characteristics follow winding code 024, which corresponds to resistance and inductance values used by matched drive amplifiers in the Indramat ecosystem.
