Product Description:

The MDD090C-N-040-N2M-110PL1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it converts electrical energy into controlled rotary motion for positioning, feeding, and indexing tasks on automated production lines. An integrated multi-turn absolute encoder delivers precise rotor position data so the drive can maintain commanded speed and torque under changing load conditions. Because feedback is built into the motor, the controller can read position immediately after startup and coordinate motion without relying on external sensing devices.

At stall, the motor can supply a continuous torque of 10.4 Nm, enabling it to hold or start loads without external gearing. Under rated electrical frequency, it reaches a nominal speed of 4000 rpm, matching fast-cycle packaging, pick-and-place, or spindle applications. A blocking brake provides 6.5 Nm of holding torque to help prevent shaft rotation during power-off or emergency-stop events. The centering diameter of 110 mm aligns the motor with the machine mounting pilot, while the power and feedback leads exit on the left side to simplify cable routing in layouts where connections must clear guards, frames, or adjacent axes. The brake also supports applications where the shaft must remain in place after the power supply is removed.

Electrical terminations are made through a sealed connector, and real-time position information is delivered through digital servo feedback (DSF). The motor has length code C, which indicates a longer active stack for this frame size and supports higher torque than shorter versions in the same diameter. The output uses a keyway shaft, and a shaft seal helps keep coolant or dust away from the output-end bearing area. A standard housing encloses the windings, and the single-ended shaft arrangement keeps the overall package compact when the motor is installed inside confined machine frames. The compact format also reduces the space needed behind the machine plate for couplings and protective covers.
