Product Description:

The MKD112A-058-GG0-BN is a servo motor built by Bosch Rexroth Indramat for the MKD Synchronous Motors series. It forms the rotary actuation element in industrial automation lines, turning drive-supplied current into controlled mechanical output so that gantries, packaging stations, or material-handling axes can index or follow motion profiles with consistent accuracy. A 112-frame housing and an A length code place the unit in the mid-power class while keeping envelope dimensions suitable for cabinets with limited depth.

This model supplies a continuous standstill torque of 15.0 Nm, giving servo drives enough holding force to resist static loads without overheating. The motor aligns with adjacent mechanics by means of its 130 mm centering diameter, a pilot surface that keeps the shaft concentric with the driven element. Mounting holes are arranged on a 192 mm square flange, a standardized pattern that matches gearboxes and brackets in the same size range. Power and feedback cabling exit on side B, so routing can remain clear of moving parts on the opposite face. The unit uses an output connector instead of captive leads, allowing rapid connection and shield continuity through circular plug-in hardware.

Position feedback is generated by a resolver, which provides analog sinusoidal signals that the drive uses for relative commutation and speed control. Because the motor is supplied without a holding brake, external locking or drive-generated torque must secure vertical axes during power loss. A plain shaft transmits torque directly and suits couplings that clamp on a smooth journal, while a shaft seal helps protect the interior bearings from coolant splash or dust. The 058 winding code identifies the stator turns and resistance used for this motor, matching its electrical characteristics to compatible MKD drives for resolver-based relative position operation.
