Product Description:
The MDD112B-L-030-N2M-130GB2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and included in the MDD Synchronous Motors series. Designed for use with digital drive controllers, it provides closed-loop torque and position control for automated machine axes, conveyors, and press drives. Its plain shaft, integrated blocking brake, and standard dynamic balancing make it suitable for mid-frame industrial installations where accurate motion and repeatable stopping are required. Because the motor works as part of a servo system, the paired controller can continuously correct for load variation, speed error, and positional drift during cyclic machine operation.
The motor can sustain a continuous stall torque of 17.5 Nm, allowing an axis to hold load without thermal overload while still producing rapid torque response when commanded. Its rated mechanical speed is 3000 rpm, so the connected drive must supply the electrical frequency needed for synchronous operation at that speed. During power-off states or emergency stops, a blocking brake rated at 40.0 Nm secures the shaft against back-driving. Mounting alignment is supported by a centering flange diameter of 130 mm, which helps maintain concentric coupling with gearboxes or belt pulleys. Rotor position is reported by an integrated multi-turn absolute encoder, which sends multi-revolution angle data to the controller and allows startup without a homing cycle. This feedback arrangement also helps the drive maintain stable positioning during indexing and speed changes.
The housing uses surface cooling, so heat is transferred through the motor body to the surrounding mounting structure. A shaft seal helps protect internal bearings from dust and coolant splash common in industrial equipment. All electrical terminations exit on side B, which can simplify cable routing when the driven load is located on the opposite face of the motor. Position and velocity loops receive high-resolution data through digital servo feedback (DSF), supporting tight control response in coordinated multi-axis motion. The grouped connection layout can also reduce cable bending near moving machine elements.
