Product Description:

The MKD112B-048-GP0-LN is a servo motor manufactured by Bosch Rexroth Indramat within the MKD Synchronous Motors series. It is intended for industrial automation axes that demand repeatable rotation, stable torque, and direct feedback to the drive controller. In a motion system, this motor transforms drive current into controlled mechanical output so that positioning tables, pick-and-place gantries, or packaging spindles can follow programmed profiles with minimal tracking error. Its operating role suits machines that require accurate speed changes, smooth indexing, and reliable response during repeated start-stop cycles.

The motor delivers a continuous stall torque of 28.0 Nm, allowing it to hold or start heavy loads without overheating. A centering diameter of 130 mm aligns the housing inside matching machine bores, while the square flange measuring 192 mm provides the bolt pattern for rigid mounting. Winding code 048 identifies the electrical setup that must be matched by the drive for proper current control, and rotor position is reported through resolver feedback (RSF), which gives analog sine-cosine signals that support fine interpolation even at standstill. This combination supports steady control response during low-speed positioning as well as during acceleration and deceleration in cyclic machine motion.

Cabling exits on the left side of the frame, and power is introduced through a single indexed power connector that keeps the connection layout straightforward. A shaft with keyway transmits torque to pulleys or couplings without slip, and a shaft seal is fitted to help reduce dust or coolant entry along the journal. The feedback system provides relative position data, so the axis must complete a homing routine before absolute machine position is known. The unit is supplied without a holding brake, making it suitable for horizontally oriented applications or systems that use external clamping, while size code 112 and length code B determine the motor's housing dimensions.
