Product Description:

The MDD112D-N-040-N2L-130GA0 synchronous motor is produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor intended for digital drive controllers, it converts controlled electrical input into rotary motion used in positioning axes, gantries, and material-handling stations. The unit belongs to size 112 of the family and carries length code D. This frame format suits servo installations that require repeatable positioning, stable speed regulation, and predictable integration with compatible control hardware.

A continuous standstill torque rating of 38.0 Nm allows the rotor to hold static loads for extended periods when thermal conditions remain within the motor's operating range. The motor reaches a nominal operating speed of 4000 rpm, giving the connected axis a broad speed range for conveyors, transfer systems, and indexing mechanisms. Position and velocity are monitored through integrated digital servo feedback, enabling the drive controller to correct load disturbances quickly and maintain smooth response during acceleration and deceleration. Power and sensor conductors exit on Side A through a keyed connector, which keeps both cable groups aligned in one direction and simplifies routing inside enclosed machinery.

Mounting alignment is assisted by a centering pilot of 130 mm, allowing repeatable shaft concentricity with couplings or gearbox inputs. The motor uses a plain shaft with a shaft seal, which supports straightforward coupling while helping limit lubricant escape at the drive end. The rotor and external fan are trimmed to a Standard balancing grade, reducing vibration during high-speed operation. Because the design is supplied without a blocking brake, holding force at standstill must be provided by drive torque or by an external mechanical locking device.
