Product Description:

The MDD112B-N-020-N2L-130GA0 is a synchronous AC servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for direct use with digital drive controllers, delivering the closed-loop rotary motion required for positioning axes, conveying stations, and coordinated machine tools. A standard housing and an internally balanced rotor support consistent dynamic response in automation cells. This layout also helps the motor fit machine spaces where predictable servo behavior and compact installation are both important. It is well suited for applications that repeat short positioning moves and require stable response during frequent starts and stops.

The motor reaches a nominal speed of 2000 rpm, allowing the drive to command precise velocity profiles without excessive mechanical stress. Continuous torque at standstill is rated at 17.5 Nm, so the shaft can support static loads while staying within thermal limits. Mounting is centered by a 130 mm pilot diameter that aligns the flange with gearboxes or machine frames. Power and feedback cabling exit on the A-side, and a removable connector allows straightforward cable attachment. The B length uses an intermediate lamination stack, which helps balance rotor inertia with the acceleration demands of medium-torque motion systems, while the plain shaft couples directly to pulleys or couplings without a keyway.

The motor is supplied without a blocking brake, so holding force at standstill must be provided by drive torque or an external locking device. High-resolution rotor position is reported by integrated digital servo feedback, allowing tight closed-loop control across the full speed range. Frame size 112 provides a balance of torque output and manageable mass for transfer axes and gantry modules. A durable shaft seal protects the front bearing from coolant splash and airborne particles, and the single-ended shaft leaves no extension on side B, which helps reduce overall machine depth.
