Product Description:

The MKD112C-058-KG3-BN belongs to the MKD Synchronous Motors series and serves as a servo motor for controlled rotary motion in automated machinery. It converts commanded current from a digital drive into precise shaft torque and speed, making it suitable for positioning tables, packaging axes, and material-handling gantries in multi-axis systems. It is intended for closed-loop motion tasks that require repeatable speed regulation and stable positioning under changing loads.

During continuous standstill operation, the motor sustains 38.0 Nm of electromagnetic torque, letting a drive hold loads without additional gearing. Accurate centering on a 130 mm pilot keeps the stator concentric with coupled mechanics, which helps reduce vibration and bearing wear. Power, brake, and sensor leads exit through an output connector that supports quick cable changes. Motion feedback is supplied by resolver feedback with an integrated encoder, giving the controller sine-cosine signals with strong noise immunity. A plain shaft is provided to mate with compression couplings or shrink discs, allowing slip-free transmission while avoiding backlash associated with keyed designs.

Load security is handled by an integrated brake that applies 70 Nm of holding torque, permitting vertical axes to remain fixed when power is removed. Installation uses a 192 mm square flange, which provides a consistent bolt pattern for compatible machine frames. All connectors face Side B, so cable runs stay parallel to the motor body and clear of moving tooling. The stator uses winding code 058, and the assembly follows the medium motor length C designation. A shaft seal isolates the bearing cavity from splash or dust. Position feedback remains valid over power cycles because the system provides absolute tracking for more than 4096 revolutions, eliminating homing sequences after power is restored.
