Product Description:

The MDD090B-N-030-N2L-110GL2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed as a motor for digital drive controllers, it converts commanded current into precise rotary motion for axes that must start, stop, and reverse rapidly in automated assembly lines, pick-and-place units, and packaging cells. Its construction supports closed-loop control so that position and speed follow controller setpoints accurately, even when load inertia or friction changes during a cycle.

At standstill, the motor supplies a continuous torque of 7.2 Nm, allowing fixtures or feed screws to hold a load without thermal drift. When power is removed, an integrated blocking brake resists back-drive with 11.0 Nm of static torque, keeping vertical or suspended axes locked. The rotor can spin up to 3000 rpm, a rating that pairs with standard inverter frequencies used in machine tools and test rigs. Precise alignment to the machine bed is achieved by a centering diameter of 110 mm, and the rotor is built to a standard balancing grade to minimize residual vibration. All power and feedback connections exit on the left side, an arrangement that streamlines conduit routing when the motor sits on right-hand bearing blocks.

The standard aluminum housing is complemented by a shaft interface that comes with a shaft seal, protecting internal bearings from coolant spray. Position data is returned through digital servo feedback (DSF), allowing the drive to re-establish absolute commutation immediately after power-up. Frame size code 090 and length code B give a compact stack height while still supporting the motor's thermal load. The shaft end remains plain, with no side-B extension, which simplifies press-fit coupling to pulleys or bellows couplings. A single locked connector handles both power and sensor conductors, helping reduce wiring complexity.
