Product Description:
The MKD112B-073-KP1-BN belongs to the MKD Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is a servo motor intended for closed-loop positioning and speed regulation on automated machinery such as gantry axes, presses, and packaging stations. By combining resolver-based feedback with an integrated encoder, the unit supplies real-time rotor data to a drive controller so that commanded motion profiles can be executed with minimal following error. This feedback arrangement helps the drive correct load-related deviations during acceleration, deceleration, and steady-speed operation.
The motor’s centering pilot of 130 mm keeps the stator concentric with adjacent mechanical frames, while a flange size of 192 mm provides standardized mounting points. During continuous operation, the rotor can deliver 28.0 Nm of torque without overheating, making it suitable for medium-load duty cycles. An enclosure rating of IP65 shields the internal windings from dust ingress and low-pressure water jets, allowing direct installation outside a cabinet. System accuracy is specified at ±8 angular minutes. This value reflects the combined mechanical and electrical tolerance the drive can maintain during interpolated motion.
The unit is equipped with a holding brake that clamps the shaft with 22 Nm of static torque, preventing drift when power is removed. Class F insulation allows the stator winding to withstand temperatures up to 155 °C, and the motor can run at ambient temperatures from 0–40 °C without derating. Absolute position tracking over >4096 revs eliminates homing cycles after each startup. Connections exit on side B through an output connector, which helps simplify cable routing along the machine frame. The B-length housing and size 112 frame balance inertia with peak torque, while the keyed shaft, shaft seal, and resolver feedback support stable mechanical integration.
