Product Description:

The MDD112B-L-030-N2L-130PB0 is produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts controlled DC bus energy from a Rexroth inverter into mechanical motion for indexing tables, gantries, and coordinated axes in automated lines. Its electromagnetic design works with external surface-cooled machine frames, allowing the drive to issue precise current commands while the motor returns positional data through an internal encoder loop.

At standstill, the motor can deliver 17.5 Nm of continuous torque, so it can hold static loads without overheating. During motion, it reaches a nominal speed of 3000 rpm, so the paired inverter and drive train must support that operating speed. A centering diameter of 130 mm provides a concentric reference between the flange and the driven machine, which helps reduce radial misalignment. All power and feedback leads exit on Side B, which can simplify cabinet routing when the shaft faces the operator, and they terminate on a sealed connector. Rotor position is reported through Digital servo feedback (DSF), allowing accurate commutation and stable current control across the speed range. The balancing is standard, which helps reduce vibration during operation.

The housing uses surface cooling, so heat is conducted into the mounting plate rather than removed by an internal fan. A shaft seal helps prevent lubricant escape and protects the bearings, while the keyway shaft provides a secure mechanical connection for pulleys or couplings. Frame designation 112 and motor length code B provide the active iron volume needed for the stated torque. The standard shaft end omits a second output on side B to conserve space. The unit is supplied without a holding brake, so external mechanical locking may be needed when the application must maintain position during a power loss.
