Product Description:

Bosch Rexroth Indramat manufactures the MDD115B-N-030-N2L-130GA0 as part of its MDD Synchronous Motors series. The unit is a permanent-magnet servo motor built for direct connection to digital drive controllers, where it supplies closed-loop torque and speed control for positioning axes, material handling stations, and similar automation tasks.

The motor can maintain a continuous holding capability of 38.0 Nm at standstill, so actuators remain stable when motion is paused. A nominal speed of 3000 min⁻¹ defines the reference operating point that pairs with typical 8-kHz PWM inverters for rapid cycle work. The centering diameter is 130 mm, providing a precise locating fit on machine endbells or adapter plates and keeping radial runout low. Rotor position is reported through Digital servo feedback; this encoder format sends absolute data packets that allow drives to recover position after power interruptions without homing. Power and feedback plugs are mounted on Side A, and the connector style streamlines cable replacement while keeping the housing—specified as standard—free of fixed glands. Standard dynamic balancing minimizes residual vibration at full speed, protecting adjacent bearings and couplings.

Mechanical options complete the adaptation to the load. The unit is supplied without a blocking brake, so external clamps or drive torque must hold vertical loads during shutdown. A sealed output end prevents lubricant escape because the shaft is equipped with a shaft seal. Frame size 115 establishes the stator diameter, while length code B increases the active iron for higher thermal capacity. The rotor carries a plain shaft that accepts friction-locked hubs; no second shaft end is present on side B, reducing overhung mass. Connection type is a circular industrial connector, and the product type tag lists this model as a motor for digital drive controllers, aligning it with Rexroth DDS and DKC inverters.
