Product Description:

The MKD112A-058-GG1-BN is a servo motor manufactured by Bosch Rexroth Indramat as part of the MKD Synchronous Motors series. Designed for integration with digital drive controllers, the unit converts electrical energy into rotational motion so automated machinery can follow commanded velocity and position profiles with repeatable accuracy on assembly, packaging, and material-handling lines. Its electromagnetic design supports rapid acceleration and precise stopping, making it suitable for interpolated axes and synchronized multi-motor applications. This operating profile also supports smooth response during indexing and other repetitive motion sequences where stable control is important.

The mechanical interface includes a flange size of 192 mm and a centering diameter of 130 mm, permitting direct mounting to gearboxes or machine frames without adapter rings. When held at standstill and supplied with rated current, the motor develops 15.0 Nm of continuous torque; this value corresponds to the continuous load capability for constant-duty operation. A built-in holding brake rated at 22 Nm locks the shaft during power loss or emergency stops. For position and velocity monitoring, the unit employs resolver feedback, a low-impedance analog transducer that withstands high ambient temperatures and vibration while supplying rotor-angle data for commutation and speed regulation.

Power and feedback cables exit on Side B through an output connector, keeping service access clear on the opposite face of the housing. The rotor uses a plain shaft for clamped coupling arrangements, and a factory-installed shaft seal helps block coolant or oil ingress at the bearing seat. Winding code 058 indicates the electrical resistance and inductance used for this 400 V class platform. The motor follows length code A and size code 112, giving it a compact envelope for medium-inertia loads, and its relative position detection mode suits applications that reference a homing sensor at startup.
