Product Description:

The MKD112C-058-GG3-BN is a servo motor manufactured by Bosch Rexroth Indramat for the MKD Synchronous Motors series. It is intended for regulated drive axes where closed-loop motion is required in assembly lines, palletizers, and general material-handling stations. By converting drive current into controlled rotary torque, the motor serves as the electromechanical element of an automation loop. Its resolver interface and coded winding allow compatible digital drives to regulate speed and position with repeatable response during indexing, transfer, and positioning tasks.

The motor frame uses size code 112, which places it in a mid-frame class for industrial motion systems. Length designation C increases stack height for higher continuous torque without enlarging the flange footprint. A flange of 192 mm and a centering diameter of 130 mm help align the housing to machine plates or gearbox faces with accurate shaft positioning. The rotor uses a plain shaft, so couplings clamp directly without keys and can help reduce backlash in precision linkages. Power and feedback conductors exit on side B through an output connector, which helps keep cable routing clear of the mounting face.

Electrical characteristics follow winding code 058, which sets the phase resistance, inductance, and thermal loading used with standard Rexroth inverters. Position data is supplied by resolver feedback, giving relative measurement for drives that calculate absolute position in software. A spring-applied brake provides 70 Nm of holding torque so vertical or high-inertia loads can remain stationary when the drive is disabled. A dedicated shaft seal blocks coolant and dust from entering the bearing cavity during washdown or dusty operation. This combination of feedback, holding brake, and shaft sealing supports steady motor operation in transfer systems and other multi-axis machinery that cycle frequently.
