Product Description:

The MKD112B-073-GP1-AN is a brushless servo motor produced by Bosch Rexroth Indramat for the MKD Synchronous Motors series. It is used on CNC machinery, packaging lines, and automated transfer gantries to deliver tightly controlled rotary motion under drive-controller commands. Integrated cooling fins dissipate heat directly to ambient air, so the motor can be mounted on the machine without external blowers. Its electromagnetic design supports continuous duty while maintaining consistent positioning during repeated start-stop cycles. This makes the motor suitable for axes that require smooth acceleration, stable speed control, and repeatable motion.

A centering diameter of 130 mm fits within a 192 mm square flange to keep the motor aligned with the driven load. Motor size 112 with frame length B provides a continuous standstill torque of 28.0 Nm, which is useful for low-speed cutting and indexing tasks. Cables exit on Side A through an output connector, which helps simplify cable routing in compact machine layouts. Resolver feedback (RSF) provides sine-cosine signals for speed and relative position processing, allowing the connected drive to track shaft movement accurately. The motor uses F-class windings, and it is intended for operation in ambient areas of 0–40 °C without derating.

The housing has an IP65 rating, and an integral shaft seal helps keep dust and low-pressure water away from the bearings. A permanent-magnet brake supplies 22 Nm of static torque to secure vertical axes when the drive is disabled. The keyed shaft provides positive torque transfer to couplings and driven components. During closed-loop operation, the control system can hold commanded positions within ±8 angular minutes, which supports accurate stopping and steady dwell behavior. This combination is useful in motion systems that must pause precisely before the next move begins.
