Product Description:
The Bosch Rexroth Indramat MKD112B-048-KP0-BN is a servo motor in the MKD Synchronous Motors series. It is built for closed-loop drive systems where accurate torque and velocity control are required on production lines, machining centers, and automated handling stations. When paired with a compatible drive controller, the unit converts commanded current into proportional rotary motion so machine axes can follow speed changes and positioning commands with repeatable accuracy. This operating role makes it suitable for applications that need stable response during both continuous movement and frequent start-stop cycles.
Its continuous torque at standstill reaches 28.0 Nm, so the axis can support static loads while staying within rated thermal limits. Mechanical alignment to gearboxes or machine frames is simplified by a 130 mm centering diameter and a square flange measuring 192 mm on each side. Power and feedback conductors exit on side B, and the integral output connector keeps the cable interface compact at the motor housing. The output uses a shaft with a keyway, which provides a positive drive connection for couplings or pulleys. Size code 112 and length code B indicate the housing envelope used for this motor variant.
Control resolution is provided by resolver feedback, which is mounted behind the shaft and supplies position information over over 4096 revolutions for operation that must recover position after a power interruption. The electromagnetic design follows winding code 048, so the matching drive setup must use the appropriate voltage and current characteristics for normal motor performance. The motor is supplied without a holding brake, so any load retention during power-off conditions must come from external mechanical restraint or drive-controlled torque where applicable. A factory-installed shaft seal helps keep coolant splash and dust away from the output end, while the keyed steel shaft and connector arrangement remain consistent with the mechanical layout used on compatible MKD112 units.
