Product Description:

The MKD112B-058-KG2-BN servo motor is produced by Bosch Rexroth Indramat within the MKD Synchronous Motors series. Designed for closed-loop drive systems, this AC machine converts electrical energy into controlled torque and speed for packaging lines, material handlers, and machine tools. By combining resolver feedback with an integrated encoder, the unit supplies absolute rotor position data to the drive, enabling synchronous operation and fast dynamic response in automated cells.

Mechanically, the motor mounts through a centering pilot of 130 mm and a square flange that measures 192 mm. Its winding code 058 gives the stator a continuous standstill torque rating of 28.0 Nm, so the axis can hold load without overheating at zero speed. Power and feedback leads exit on side B, where the connection interfaces use a single output connector for quick installation. The plain shaft is protected by a factory-installed seal, and the F-class insulation system withstands winding temperatures up to 155 °C. Size designation 112 and length code B place the motor in the mid-frame range of the series, balancing inertia with compact length.

Environmental and measurement features support dependable field use. The housing carries a protection rating of IP65, blocking dust ingress and low-pressure water jets when the mating connectors are fitted. Normal operation is specified for ambient conditions between 0–40 °C without derating. Integrated resolver electronics provide absolute position detection over more than 4096 revolutions, which simplifies homing routines and permits multi-turn monitoring. Combined with a system precision of ±8 angular minutes, the motor maintains tight path accuracy in multi-axis gantries. A plain shaft geometry minimizes backlash, and the sealing arrangement keeps lubrication contaminants away from the bearings.
