Product Description:

The MDD093B-N-020-N2L-130PB1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is designed for integration with digital drive controllers where precise torque and velocity regulation are required in automated machinery, pick-and-place axes, and packaging lines. The model supports closed-loop operation through its internal encoder and occupies the 093 frame class, making it a mid-range option between the smaller 071 units and the higher-power 112 designs.

The motor delivers a continuous standstill torque of 14.5 Nm, allowing it to hold static loads without overheating when the shaft is locked by the drive. During motion, the rotor can reach a nominal speed of 2000 rpm, which is the rated operating point for sizing gear ratios or belt drives. A blocking brake rated at 11 Nm is mounted to secure vertical or suspended axes whenever power is removed. Feedback to the controller is provided by digital servo feedback (DSF), enabling high-resolution position tracking for interpolated moves. Accurate mechanical alignment is supported by a centering diameter of 130 mm, which mates with standard pilot registers on gearbox flanges and mounting fixtures. Standard housing and rotor balancing eliminate the need for additional counterweights, and the rear connector style simplifies cable installation in tight enclosures.

Protective features include a shaft seal that limits lubricant migration and blocks airborne particles from reaching the bearing set. All power and encoder plugs are oriented toward Side B of the stator, simplifying service access in cabinets where the opposite face abuts other modules. Within the series, size code 093 indicates the overall stator diameter, while length code B corresponds to a medium active core that balances thermal mass and dynamic response. A machined keyway on the shaft end provides positive mechanical locking for couplings or pulleys, and the absence of a second shaft extension on the rear side keeps the motor length compact for inline drive layouts.
