Product Description:

The MDD090B-N-040-N2M-130PA0 is a three-phase synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified for use with digital drive controllers, it integrates directly with Rexroth drives in packaging, material-handling, and machine-tool axes. The 090 frame size and B length code give it a mid-range footprint, and the rotor uses the standard balancing grade to help reduce vibration during operation. A cast-aluminum housing encloses the stator windings, and the built-in multi-turn absolute encoder provides position and commutation data to the drive without requiring an external transducer. This combination makes the unit suitable for axes that require repeatable positioning, stable servo response, and compact mechanical integration.

At standstill, the motor can supply 7.2 Nm continuously without thermal overload, and it reaches a nominal rotor speed of 4000 rpm when powered by a compatible drive. The flange face carries a centering pilot of 130 mm that aligns the motor accurately with the machine frame. Closed-loop regulation is achieved through Digital servo feedback, which sends precise position data to the controller for stable motion control. The motor is delivered without a blocking brake, so holding force must be provided externally when the axis is at rest. These operating values suit feed axes, indexing tasks, and handling motions that need fast response from a digitally controlled servo system.

Power and signal terminations are oriented toward Side A, and a keyed connector mates with the drive cable for a secure connection. The shaft exit is protected by a shaft seal, which helps limit the entry of fine dust or oil mist. Output torque is transferred through a keyway machined into the primary shaft, while the opposite face remains blank because the motor has no shaft extension on side B. This arrangement helps keep the motor practical for enclosed machine layouts where cable access and shaft protection both matter.
