Product Description:
The MDD112B-N-030-N2L-130GA1 is a synchronous AC servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for digital drive controllers, it turns commanded current into proportionate electromagnetic torque so that automated axes track position and speed references with repeatable accuracy. The integrated motor electronics forward absolute rotor data to the controller, making the unit suitable for high-demand assembly, packaging, and material-handling equipment. Its synchronous design also supports controlled motion where quick response and stable feedback are needed during repeated start-stop cycles.
It supplies a continuous standstill torque of 17.5 Nm, allowing the drive system to maintain force at zero speed. The rotor sustains a nominal speed of 3000 rpm, matching servo drives that modulate current at high frequency. The blocking brake delivers 14.0 Nm of torque so the axis stays fixed when power is removed. A 130 mm centering diameter positions the flange concentrically with adjacent machine parts, while motor size 112 indicates a square stator envelope that fits standard MDD mounting holes. This combination of standstill torque and rated speed supports axes that must start smoothly, accelerate quickly, and hold position accurately between moves.
Electrical and feedback connections exit on Side A, simplifying cable routing inside compact cabinets, and are completed by a sealed circular connector. Position data is transmitted through digital servo feedback (DSF), enabling fine interpolation for coordinated multi-axis motion. A shaft seal protects the front bearing from coolant splash, and the plain shaft interface allows direct coupling to timing belts or planetary gearheads. Keeping power and feedback on the same end reduces cable sweep around the motor body and helps when space behind the machine frame is limited. The absence of a secondary shaft end conserves space, and the standard housing geometry supports responsive acceleration in tightly arranged machinery.
