Product Description:

The MDD112A-N-020-N2M-130GB0 is a three-phase AC servo motor manufactured by Bosch Rexroth Indramat for use with digital drive controllers. As part of the MDD Synchronous Motors series, it converts commanded current into controlled rotational motion for positioning, conveying, and other cycle-driven tasks in industrial automation. The motor is intended for closed-loop axis control, where the drive regulates torque and speed in real time during starts, stops, and repeated direction changes. It can be used on feed drives, transfer units, and rotary indexing stations where quick response is important.

With a centering diameter of 130 mm, the frame aligns precisely to mounting flanges, while the standard housing and standard dynamic balancing help limit vibration during operation. Power and feedback plugs are oriented on Side B, and a factory-installed Connector keeps the electrical interface compact at the rear of the motor. At standstill, the motor can deliver 10.5 Nm of continuous torque, which supports holding force during dwell periods or slow indexed movement. Under rated excitation, it reaches a nominal speed of 2000 rpm, a value matched to the 112-size stator for medium-capacity handling axes. The A-length construction keeps the motor short, which helps when surrounding machine space is limited.

Position data are generated by the integrated multiturn absolute encoder, allowing the controller to recover rotor position after power is restored. Absolute position retention is useful on axes that should resume control without a reference move after a power interruption. Closed loops receive digital servo feedback (DSF), which provides stable electronic feedback without relying on analog signal behavior. Because the unit is supplied without a blocking brake, vertical or suspended loads need a separate holding method when power is off. A shaft seal protects the internal bearings from contamination, and the plain shaft is intended for use with external couplings. These features support accurate servo operation in compact machine axes that need repeatable motion and direct feedback from the motor.
