Product Description:

The MKD112B-048-KG2-AN is a servo motor built by Bosch Rexroth Indramat for the MKD Synchronous Motors series. It converts electrical energy into controlled rotary motion for positioning tasks in automated machinery, where repeatable speed and torque are required for axes such as conveyors, gantries, or tool spindles. The design is intended for closed-loop servo applications that need stable response during repeated acceleration, deceleration, and holding periods. Power and feedback leads exit on Side A, which keeps cable routing on one side of the machine and simplifies installation in compact equipment.

This unit produces a continuous standstill torque of 28.0 Nm, allowing it to hold or slowly index loads without overheating. That output is useful for axes that spend time at standstill while maintaining a commanded position. A centering diameter of 130 mm aligns the housing to the driven machine frame and helps reduce radial runout during installation. Motion feedback is provided by resolver feedback with an integrated encoder, combining commutation data with position signals for use with compatible drives. The enclosure is rated IP65, which keeps out dust and resists low-pressure water jets for use on open production lines.

A flange size of 192 mm provides a broad mounting face that spreads loads across the machine interface. System precision is specified at ±8 angular minutes, and acceptable ambient temperatures of 0–40 °C suit typical factory floors without external chillers. Winding code 048 corresponds to electrical values used with matching drives, and the motor also includes an output connector, F-class insulation for 155 °C winding limits, absolute position detection over more than 4,096 revolutions, and a B motor length within the 112 frame. The motor uses a plain shaft for external couplings, and the shaft seal helps keep coolant away from internal components.
