Product Description:
Bosch Rexroth Indramat manufactures the MDD112B-N-030-N2M-130PA3, a servo motor in the MDD Synchronous Motors series. This motor is intended for direct coupling to digital drive controllers that require fast torque buildup in automated material-handling lines, packaging machines, and machining centers. By converting drive current into controlled mechanical output, it serves as the drive element in closed-loop axes where positional repeatability and high cycle rates are important. It is well suited for positioning and feed applications that need stable response under changing load conditions.
The motor provides a continuous standstill torque of 17.5 Nm, allowing steady force output during prolonged positioning or low-speed feed movements. Under rated voltage and excitation, it reaches a nominal speed of 3000 rpm, so many systems can achieve working speed without additional reduction stages. A built-in blocking brake supplies 60.0 Nm of holding torque to secure vertical loads when power is removed. Mounting accuracy is supported by a centering diameter of 130 mm, which helps align the motor on the machine interface. Cable exit is arranged on side A for straightforward routing, and the motor also uses an integral shaft seal, standard balancing, a standard cast-alloy housing, and length code B within the 112 frame size.
Control precision is supported by an integrated multiturn absolute encoder that reports rotor position through digital servo feedback (DSF), allowing the drive to close position loops without external sensors. Because the feedback system is absolute and multi-turn, position information remains available after startup without a reference run. Power and feedback conductors connect through a connector interface, which keeps the electrical connection compact and direct. The output uses a shaft with a keyway, so it mates with standard couplings and pulleys. The motor also has a single-ended shaft configuration, which reduces rear extension and helps when installation space is limited.
