Product Description:

The MKD112A-058-GG0-AN is a servo motor produced by Bosch Rexroth Indramat for the MKD Synchronous Motors series. As a permanent-magnet AC unit, it provides closed-loop torque and velocity control for positioning axes, conveyors, and handling equipment in automated cells. The motor couples directly to digital drive electronics, converting commanded current into mechanical rotation without an intermediate gear stage. Its frame dimensions fit common mounting patterns used in industrial machinery.

At standstill, the motor can supply 15.0 Nm of continuous torque, supporting low-speed feed operations without thermal overload. A centering collar of 130 mm keeps the stator concentric with the machine plate, while the 192 mm square flange carries fastening holes that transfer reaction forces into the frame. Motion feedback is obtained from an RSF device that provides resolver feedback for rotor position sensing and commutation. The housing is rated IP65, which helps keep dust out and protects the windings from water jets. Thermal endurance relies on F insulation, allowing winding temperatures up to 155 °C. A plain shaft transmits torque directly, and a shaft seal helps block lubricant migration while the lack of a holding brake keeps the assembly lighter.

Power and feedback connections leave on side A through an output connector that faces the drive cabinet, which can simplify cable routing inside the machine. With motor size 112 and length A, the unit fits a mid-range mechanical envelope while keeping inertia moderate for responsive control. Its 058 winding matches nominal bus voltages used in standard drive controllers, and the feedback system supports homing with an external reference at startup. Closed-loop accuracy remains within ±8 angular minutes, and continuous duty is permitted when ambient air stays between 0–40 °C.
