Product Description:

The MDD112C-N-020-N2M-180GB2 is a synchronous motor built by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. It is intended for direct coupling to digital drive controllers, providing closed-loop rotary motion in automated machinery, material handling axes, and packaging equipment. The motor converts regulated stator current into controlled shaft torque and speed for coordinated multi-axis operation. This type of drive arrangement is commonly used where repeatable positioning and stable speed control are required during frequent start-stop cycles.

The motor develops a continuous standstill torque of 28.0 Nm, allowing it to hold or slowly position mechanical loads without overheating. Its nominal speed rating is 2000 rpm, which suits medium-inertia applications that require controlled acceleration and deceleration. Mechanical alignment in the mounting flange is supported by a centering diameter of 180 mm, which provides an accurate locating fit against the machine frame. Power, brake, and feedback conductors exit on Side B, which can help keep cable routing away from the driven load. Rotor position is measured by an integrated multi-turn absolute encoder, so the controller receives absolute position data over multiple revolutions after power is restored.

An internal blocking brake supplies 40.0 Nm of holding torque to secure vertical or suspended loads whenever the drive is disabled. Command and diagnostic signals return to the controller as Digital servo feedback (DSF), which supports accurate commutation and motion control during reversals and low-speed operation. The output shaft is a plain shaft that can be matched with suitable external hubs or clamping elements, and all electrical terminations are made through a single connector housing that resists loosening from vibration. The motor also includes standard dynamic balancing, a shaft seal for dust and coolant exclusion, motor length code C, and a size 112 frame for installations that need a medium-power servo motor with a compact mounting format.
