Product Description:

The MDD115A-N-030-N2L-130GA0 is a synchronous servo unit manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it delivers commanded motion to automated tooling, pick-and-place axes, and packaging stations. The 115 frame size combined with the compact length code A allows the motor to fit where installation space is limited while still meeting inertia targets. A standard housing encloses the windings and bearings, providing the durability expected for general-purpose plant floor service. This layout suits compact machine sections where guards, conveyors, or adjacent tooling leave little room around the motor body.

At a nominal speed of 3000 rpm, the stator field steps fast enough to support rapid machine cycles. At standstill, it can sustain 28.0 Nm of continuous torque, so the motor can maintain load under commanded current without overheating the windings. The mounting flange centers on a 130 mm pilot diameter, ensuring concentric alignment with gearboxes or belt pulleys. Rotor position is returned through digital servo feedback (DSF), giving the controller repeatable sub-milliradian data for commutation and speed regulation. A plain shaft simplifies hub coupling and minimizes radial runout, and the rotor is balanced to limit vibration at full speed.

Power and feedback plugs are oriented toward Side A, and an integrated connector reduces assembly time by eliminating loose glands. A factory-installed shaft seal guards the front bearing against fluid ingress, while the shaft end is supplied in the standard configuration without a side-B extension to save envelope length. That arrangement keeps the rear of the motor compact and helps simplify cable routing in tight cabinets or machine frames. The unit is delivered without a blocking brake, so holding force during power-off conditions must be supplied by drive torque or an external clamp.
