Product Description:
The MDD112D-N-040-N2M-130PB2 is a servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for direct coupling to digital drive controllers, the unit converts commanded current into tightly regulated rotary motion for positioning, cutting, and indexing tasks across automated machinery. It is intended for use with digital drive controllers, and the standard housing style maintains mounting consistency within the series. This layout supports compact axis assemblies where the motor, feedback device, and mounting features need to fit within a predictable installation envelope.
The stator-rotor system produces a continuous standstill torque of 38.0 Nm, which keeps loads steady when the axis is energized but not moving. Under rated electrical conditions, the shaft can spin at 4000 rpm, supporting high-speed tooling requirements in cutting, transfer, and indexing applications. A blocking brake rated for 40.0 Nm holds the shaft when power is removed, helping prevent back-driving on vertical axes and other gravity-loaded mechanisms. Precise centering during installation is set by a 130 mm pilot diameter, and standard dynamic balancing reduces vibration throughout the speed range. Position feedback is handled through digital servo feedback generated by an integrated multiturn absolute encoder that reports absolute position over multiple revolutions. The motor has frame size 112 and length code D, which provide high thermal mass while keeping the footprint manageable for retrofit work.
Power and feedback leads exit through a connector on side B of the enclosure, allowing cleaner cable routing inside tight cabinets and along machine frames. The primary shaft end has a keyway for positive torque transfer, and no secondary shaft is provided on the opposite end. The motor is supplied with a shaft seal, which helps limit lubricant loss and blocks coolant splash during operation. This arrangement is useful in enclosed machinery where routing space is limited and shaft-end contamination must be controlled.
