Product Description:

The MDD112D-N-020-N2L-130PB2 is an AC synchronous servo motor produced by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. It is engineered for digital drive controllers, giving closed-loop speed and position control to automated machine axes, material-handling gantries, and packaging equipment. By combining a permanent-magnet rotor with high-resolution feedback, the unit converts electrical power from an Indramat drive into precisely regulated mechanical rotation for industrial automation tasks.

The motor can deliver a continuous standstill torque of 38.0 Nm, allowing steady force production when the shaft must hold a load without motion. During routine operation, it reaches a nominal speed of 2000 rpm, which suits drive output frequencies common in rapid-cycle machinery. A blocking brake rated at 40.0 Nm is integrated to secure the axis when power is off, preventing back-driving by gravity or external forces. The 130 mm centering pilot simplifies flange alignment and helps keep rotor concentricity within tight tolerance bands. Standard balancing minimizes residual vibration at full speed, and the shaft’s plain cylindrical journal uses a keyway to transmit torque without slippage.

Cables exit on the rear face because the power and feedback plugs are oriented toward Side B, which can help cable routing when the motor is mounted nose-down. A sealed circular connector handles the three-phase supply conductors and brake leads, while a second plug routes encoder signals based on digital servo feedback for position loops in the controller. An integral shaft seal sits behind the front bearing to block coolant spray or oil mist from entering the housing. The motor uses length code D in the 112 frame, which gives it the housing dimensions and bolt pattern associated with this configuration.
