Product Description:

The MKD112A-058-KG1-AN is a servo motor produced by Bosch Rexroth Indramat and supplied within the MKD Synchronous Motors series. In industrial automation, this motor converts controlled three-phase electrical input into accurately regulated mechanical rotation for positioning axes, feed drives, and handling modules. Integrated resolver feedback, a built-in holding brake, and a sealed housing let the unit operate as a closed-loop actuator where compact size and dependable synchronous torque are required.

At standstill, the rotor can sustain a continuous torque of 15.0 Nm, allowing it to hold mechanical loads without overheating. The mounting interface follows a 192 mm square flange pattern and centers on a 130 mm pilot to keep the stator concentric with attached machine frames. The housing is sealed to IP65, so dust and water jets do not affect the windings or bearings. Thermal performance remains stable between 0–40 °C, matching typical cabinet or shop-floor conditions. Position and velocity signals are generated by resolver feedback, and the connection is routed through an output connector on Side A, which simplifies cable runs in multi-axis assemblies. Insulation class F supports higher winding temperatures, while the A-length body and size 112 stator outline help reduce overall mass. A plain shaft transmits torque directly to couplings or pulleys without key slots. This shaft style is commonly used with clamp couplings or similar hub connections.

A holding brake delivers 22 Nm of static torque to secure vertical loads during power loss. This is useful where the load must remain in place when electrical power is removed. Motion accuracy is aided by a system precision of ±8 angular minutes, and the absolute position detector tracks more than 4,096 revolutions to eliminate homing cycles. Winding code 058 indicates the resistance and inductance values used for drive matching. A fitted shaft seal helps block lubricant escape and contaminant entry, and the plain output journal supports smooth coupling engagement for low-vibration service.
