Product Description:

The MKD112B-024-GG1-AN is a servo motor produced by Bosch Rexroth Indramat for the MKD Synchronous Motors series. In automation cells, this motor couples to digital drive controllers to deliver programmable speed and torque, ensuring accurate motion profiles for machining centers, transfer lines, and material-handling stations. The motor’s electromechanical design allows rapid response, while its integrated holding brake maintains load position when power is removed, making the device suitable for vertical axes and indexed conveyors.

At standstill, the motor can provide a continuous torque of 28.0 Nm, allowing it to hold or slowly index heavy loads without overheating. A built-in holding brake supplies an independent braking torque of 22 Nm, so additional mechanical locking devices are not required in gravity-loaded axes. Installation is guided by the square mounting flange that measures 192 mm, while the centering pilot of 130 mm aligns the housing to the machine frame to minimize runout. The rotor uses a plain shaft for connection to suitable couplings or clamping hubs. The motor has length code B and frame size 112, which set the overall envelope and inertia profile. A shaft seal is fitted to limit lubricant migration into the feedback cavity.

Electrically, the three-phase stator uses winding code 024, which sets the voltage constant and current requirements expected by standard Indramat power modules. Rotor position is measured by the integrated Resolver feedback (RSF) device that provides analog sine-cosine signals for relative position detection, enabling smooth vector control across the full speed range. Both power and feedback conductors exit on Side A of the housing through a single output connector, which simplifies cable routing inside cabinets or gantry carriers. This arrangement helps reduce harness complexity and supports stable operation in multi-axis systems.
