Product Description:
The MKD112B-048-KG0-BN is a servo motor produced by Bosch Rexroth Indramat for the MKD Synchronous Motors series. It converts controlled drive current into repeatable rotary motion so that indexing tables, packaging stations, and material-handling axes can reach commanded positions with stable response. The motor uses a 112 mm frame with medium B length, giving a balance between torque density and installed mass for direct machine mounting. This makes it suitable for machinery that performs frequent starts, stops, and short indexing moves. In closed-loop service, the motor supports steady acceleration and repeatable stopping behavior with compatible Rexroth digital drives.
The motor can deliver a continuous standstill torque of 28.0 Nm, allowing long-term holding or low-speed operation without thermal overload. Accurate mechanical alignment is supported by a 130 mm centering diameter, while a square 192 mm mounting flange provides standardized bolt spacing for gearboxes or couplings. Position feedback is produced by integrated resolver feedback; this analog sensor, together with absolute tracking of more than 4096 revolutions, feeds the drive with precise angle data for each electrical revolution. The feedback system lets the controller monitor rotor angle continuously during acceleration, low-speed positioning, and direction changes. The flange and centering geometry also help reduce alignment error when the motor is coupled to driven equipment.
The electrical winding is identified as 048, a code that sets the resistance and inductance needed for pairing with designated power modules. Power and feedback leads exit on side B through a single output connector, simplifying cable routing where right-side service access is preferred. The single-connector arrangement keeps the connection area compact and helps simplify routing in crowded machine layouts. The motor has a plain shaft for coupling to bell housings or pulleys, and it includes a shaft seal that limits lubricant migration and the ingress of fine particles. Because the unit is supplied without a holding brake, stationary loads must be secured by external mechanics or drive torque when power is removed.
