Product Description:

The MDD090B-N-030-N2L-110PL0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts commanded current into controlled rotary motion for positioning, feed, or spindle functions on automated machinery. Its synchronous design gives the drive precise control over torque and speed, which helps the axis remain stable during acceleration, steady running, and short dwell periods. The motor is suited to closed-loop applications where repeatable motion and predictable response are required throughout continuous production cycles.

At standstill, the rotor can deliver a continuous torque of 7.2 Nm, indicating the sustained load it can hold without exceeding its thermal limit. The winding supports a nominal speed of 3000 rpm, so the axis can reach common machining or conveying velocities when supplied by a compatible AC drive. Position and velocity are reported through digital servo feedback, which sends high-resolution signals to the controller for closed-loop correction. A centering diameter of 110 mm aligns the flange to the machine frame, and the output shaft uses a keyway for positive torque transfer. All power and feedback plugs are oriented on the left side, which helps keep cable routing consistent in multi-axis layouts, and a fitted shaft seal helps keep oil or dust from migrating into the motor interior.

The motor is supplied without a blocking brake, so vertical or suspended loads need external holding when power is removed. Size code 090 places the unit in a midrange frame, while length code B gives additional active motor length without changing the general mounting concept. A single-ended shaft leaves side B without a shaft extension, which can simplify coupling and guarding in compact assemblies. Electrical termination is handled by a molded connector, providing a fixed interface for motor power and feedback leads. Standard balancing and the standard housing pattern support smooth running and reliable mechanical fit in machine assemblies.
