Product Description:

The MDD090B-N-020-N2M-130PA2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for connection to digital drive controllers, it converts commanded current into precisely regulated rotary motion for automated axes. By coupling directly to feed screws, indexing tables, or gantry joints, the unit supplies controlled torque without mechanical backlash and supports accurate velocity and position profiles in industrial machinery. This operating role suits equipment that depends on repeatable motion during positioning, interpolation, and speed-controlled travel.

During continuous operation, the rotor reaches a nominal speed of 2000 rpm, which stabilizes velocity at the electrical frequency selected by the drive. At standstill, it can deliver 7.2 Nm of torque, allowing systems to overcome static loads before acceleration begins. The flange incorporates a centering shoulder of 130 mm, which helps seat the motor concentrically against the machine face. All power and feedback conductors exit on side A, which can simplify cable routing when the control cabinet is located on that side. A single locking connector is used instead of fixed pigtails, so the wiring interface remains compact and secure.

For axes that must remain stationary when power is removed, an internal brake supplies 11.0 Nm of holding torque through a spring-applied, electrically released mechanism. Rotor angle is reported by an integrated multi-turn absolute encoder, and those position values are transmitted as digital servo feedback to the controller for closed-loop regulation. Torque is transferred through a shaft with a keyway, and a factory-fitted shaft seal helps protect the front bearing from dust or oil mist commonly found on production lines. This arrangement supports stable feedback and secure mechanical coupling during frequent starts, stops, and reversing cycles.
