Product Description:

The MDD112C-N-020-N2L-130PA0 is a synchronous servo motor produced by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts electrical power into regulated mechanical motion for positioning and velocity control in automated equipment. The design follows the motor size 112 platform, uses a standard housing, and carries standard rotor balancing that suits a broad range of panel-mounted axes.

Its continuous torque at standstill is 28.0 Nm, so the axis can maintain load force without motion when energized. The rotor is rated for a nominal speed of 2000 rpm, matching drive controllers that require precise speed loops. A centering diameter of 130 mm aligns the stator to the machine frame and helps limit radial runout during installation. All power and feedback conductors terminate through a connector on the motor end bell, and these connections are routed on side A to simplify cable routing. Closed-loop position data is supplied by digital servo feedback, allowing the drive controller to monitor rotor position continuously during operation. The motor length code is C, which gives the unit an intermediate stack height and moderate inertia.

A keyway shaft transmits torque positively into couplings, while a factory-installed shaft seal helps limit internal contamination when the motor is mounted in IP65 enclosures. The model is supplied without a holding brake, so vertical or suspended loads must be secured by external means whenever the drive is de-energized. The shaft end is present only on the drive side, which avoids extra projection on the opposite end of the motor. Standard housing cooling relies on convection, with no liquid cooling or forced-air provisions included. With its standard balancing grade, the rotor can be directly coupled to gearboxes or belt pulleys without additional trim.
