Product Description:
The MKD112B-058-GG0-AN is a three-phase servo motor manufactured by Bosch Rexroth Indramat within the MKD Synchronous Motors series. This motor provides closed-loop rotary actuation for positioning axes, indexing tables, and similar automation elements where accurate speed and torque delivery are required. By combining permanent-magnet excitation with resolver feedback, the unit operates as the electromechanical link between the drive amplifier and the mechanical load, converting commanded current into precise angular motion for factory machinery. Its construction follows the demands of modular drive systems used in packaging, printing, and material-handling lines.
Mechanically, the motor attaches through a standard IEC flange whose outside dimension is 192 mm, while centering is achieved with a 130 mm pilot to maintain concentricity during installation. When energized, it can sustain a continuous standstill torque of 28.0 Nm, allowing high holding force without overheating. The rotor corresponds to motor size 112 and the B length code, so thermal mass and stack height balance dynamic acceleration against available machine space. Output power is transmitted through a plain shaft, and contamination ingress at this interface is limited because a shaft seal is fitted. These features support use in moderate-duty environments without added mechanical covers.
Electrical interfacing is simplified because the power and feedback leads exit on Side A and use an output connector for a compact connection point. Rotor position is measured by resolver feedback, providing analog angle information suited for drives that sample high-resolution sine-cosine signals. The stator uses the 058 winding code, which indicates the voltage constant and nominal speed range so drive matching can stay within amplifier current limits. Because the motor is supplied without a holding brake, any vertical axis must rely on external clamping if power-off locking is required. Relative position detection allows incremental homing routines at system startup.
