Product Description:
The MKD112B-048-EG0-BN is a servo motor manufactured by Bosch Rexroth Indramat and supplied within the MKD Synchronous Motors series. Designed for closed-loop axis control, it converts drive output into precise rotary motion for positioning tables, packaging stations, and material-handling units on automated lines. When used with a compatible drive controller, it supports rapid acceleration, stable velocity regulation, and repeatable stopping behavior in machines that cycle frequently. This makes it suitable for indexing, transfer, and synchronized motion tasks where short response time matters. The motor uses feedback devices and windings optimized for dynamic duty cycles rather than continuous base-speed rotation.
With a continuous stall torque of 28.0 Nm, the unit can hold or drive moderate loads without exceeding thermal limits. Mounting interfaces follow a flange square of 192 mm and a centering diameter of 130 mm, providing a repeatable fit to gearboxes or machine frames. Power and feedback leads exit on Side B and are routed through an Output connector, which keeps connections compact and simplifies cable routing at the rear of the housing. Winding code 048 indicates the electrical resistance and inductance profile used with compatible inverters. The B-length rotor stack increases magnetic flux, and the motor is supplied without a holding brake to reduce mass and inertia.
The windings use Class F insulation, allowing internal temperatures up to 155 °C. The housing meets IP65, blocking dust and low-pressure water jets when the mating connector seals are engaged. The motor has a plain shaft with a shaft seal, supporting direct-coupled connections while helping prevent lubricant migration and contaminant entry near the bearing area. The shaft seal also supports use in installations exposed to light splash or airborne debris. Operation is specified between 0 – 40 °C ambient, which suits typical indoor industrial installations. The 112 frame size balances torque density with machine footprint for multi-axis equipment.
