Product Description:
The MKD112B-058-KP2-AN is a brushless AC servo motor produced by Bosch Rexroth Indramat for the MKD Synchronous Motors series. It is intended for closed-loop positioning and velocity control in automated machinery where stable torque output and accurate feedback are required. In typical use, the motor works with a compatible drive amplifier to convert commanded current into controlled rotary motion for indexing axes, transfer systems, and other synchronized machine functions. Integrated position feedback lets the controller monitor rotor angle during operation so motion remains stable during acceleration, deceleration, and low-speed holding.
The housing uses a 130 mm pilot diameter to align the motor with the machine flange and help limit runout during installation. Its continuous stall torque is 28.0 Nm, which supports load holding at low speed without exceeding the motor’s thermal limits during normal operation. Position data is supplied through resolver feedback, a feedback method that remains reliable under shock and temperature variation. Mounting is based on a 192 mm square flange, and the output connector exits on Side A so cables can be routed parallel to the motor body. The enclosure is rated to IP65, and the winding system uses F-class insulation for the motor’s thermal design.
Power is transmitted through a shaft with a keyway, and a shaft seal is fitted to reduce lubricant loss when the axis is mounted vertically. The sealed shaft area also helps protect the bearing zone from contaminants near the driven machine. Repeatability is supported by a system precision band of ±8 angular minutes, which helps the motor maintain consistent positioning in cyclic motion. Ambient operation is permitted from 0–40 °C, matching typical conditions in fan-cooled industrial cabinets and enclosed machine sections. The motor uses size code 112 with length designation B, and winding code 058 identifies the electrical configuration used with the matching drive amplifier.
