Product Description:

The MKD112A-058-KP0-BN is a servo motor built by Bosch Rexroth Indramat for the MKD Synchronous Motors series. As a rotary actuator, it converts drive current from a digital controller into precise shaft rotation for positioning and velocity loops in automated machinery, packaging stations, and material-handling axes. Its construction follows the standard dimensions of the series for consistent mechanical integration. The motor also returns feedback to the drive, which supports coordinated multi-axis motion and repeatable changes in speed and position.

The motor develops a continuous standstill torque of 15.0 Nm, allowing static holding or low-speed feed operation without thermal overload. It mounts through a 192 mm square flange and uses a 130 mm centering diameter to align the housing with gearboxes or direct couplings. Power and sensor leads exit on Side B through a sealed connector, which keeps cable routing at the rear of the motor. The shaft uses a keyway for torque transmission, and a factory-installed shaft seal helps prevent lubricant migration. The housing is rated IP65, while Class F insulation supports elevated internal temperatures. The motor is supplied without a holding brake, so power-off load retention must be provided by external machine hardware.

Rotor position is measured by a resolver with integrated encoder functions, and the feedback system provides Absolute (>4096 revs) data immediately after power-up. That arrangement can reduce the need for a reference move when the axis is restarted. Control accuracy is held within ±8 angular minutes, which suits indexing tables and synchronized belt drives. Winding code 058 identifies the electrical characteristics used by the matching drive. Operation is specified for ambient temperatures from 0–40 °C, allowing rated performance in typical enclosures without forced cooling.
