Product Description:

The MDD112C-N-030-N2L-130PB2 is a synchronous AC servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers wherever accurate closed-loop speed and position control is required in automated handling equipment, packaging stations, and gantry axes. Its synchronous design supports repeatable motion during frequent starts, stops, and speed changes in normal machine operation. The rotor is balanced to the standard grade to keep vibration within limits, the housing is supplied in standard form for direct mounting, and a shaft seal at the output end allows use in light oil-spray environments.

The motor produces a continuous stall torque of 28.0 Nm, allowing constant load support without exceeding thermal limits. Under drive excitation, it reaches a base speed of 3000 min⁻¹, providing a direct mechanical match for many high-speed transmission stages. Cables exit through a connector on Side B, which keeps the shaft face clear for coupling and mounting access. Mechanical power is delivered through a shaft with a keyway that accepts standard taper bush couplings. Rotor position is reported through Digital servo feedback (DSF), allowing the controller to regulate phase current and position accurately. The design omits a shaft extension on the opposite side, which shortens the overall motor length and simplifies guarding.

An integral blocking brake delivers 40.0 Nm of static torque, preventing back-driving on suspended or vertical axes during power loss. The machined pilot has a diameter of 130 mm, which aligns the stator concentrically with gearboxes and mounting plates. The motor uses frame code 112 and length code C. This combination gives the motor the deepest lamination stack in this family and increases thermal mass for short overload periods.
