Product Description:

The MDD112D-N-030-N2L-130PB2 is a synchronous motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it delivers precise rotary motion to automated machine axes where rapid positioning and repeatable speed regulation are required. The unit combines electronic feedback, mechanical alignment features, and a standardized connection layout for use in packaging, material-handling, and tooling equipment. This arrangement allows the motor to work in servo systems that depend on closed-loop feedback for fast response during indexing, positioning, and speed-controlled travel.

At standstill, the motor can sustain a continuous torque of 38.0 Nm, allowing it to hold load without exceeding thermal limits. During operation, it reaches a nominal speed of 3000 rpm, providing stable velocity for servo loops. A centering diameter of 130 mm aids concentric alignment with gearboxes or mounting flanges, which helps reduce radial runout. The frame uses size code 112, giving a larger stator cross-section for the rated torque. Power and feedback leads exit on side B, and the single connector interface keeps wiring compact. Standard housing and balancing limit vibration to normal industrial levels, and a shaft seal helps keep airborne contaminants out of the bearing cavity.

The motor body uses length code D, which provides extra stack height for higher thermal mass and a longer shaft extension. A built-in blocking brake supplies 40.0 Nm of static torque so vertical or oscillating axes remain fixed when power is removed. Position data returns to the drive through digital servo feedback (DSF), allowing high-resolution commutation without an external encoder. For mechanical coupling, the shaft uses a keyway to provide positive drive engagement and reduce slippage during repetitive start-stop cycles. The motor has a standard shaft end on the drive side, and there is no secondary output on side B.
