Product Description:

The MDD090A-N-020-N2M-130PA0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is supplied as a drive-controlled actuator for industrial automation, where precise velocity and position loops are closed inside dedicated digital controllers. This design suits compact multi-axis machinery such as pick-and-place stations, feeders, and light conveyors that require repeatable motion under electronic supervision. In these applications, the motor is used where compact dimensions and predictable servo response are important for consistent axis movement.

This model develops a continuous standstill torque of 3.7 Nm, which provides a suitable baseline for low-inertia axes that must hold load at rest. During dynamic operation, it reaches a nominal speed of 2000 rpm, matching the thermal and magnetic capability of the compact A-length stator. Mounting alignment is simplified by a centering flange that measures 130 mm in diameter. Power and feedback conductors exit on Side A through a keyed connector, which supports straightforward cable routing at the cabinet interface. The motor uses standard housing and balancing to reduce vibration, and it is supplied without a blocking brake, so power-off holding must be provided externally.

Feedback is provided by an integrated multi-turn absolute encoder and transmitted as Digital servo feedback (DSF), so the controller can read position data immediately after power-up. This arrangement supports stable closed-loop operation in coordinated axes and helps the motor maintain accurate positioning during repeated motion cycles. Output torque is delivered through a keyway shaft, and a shaft seal helps limit lubricant migration into the stator cavity. Standard balancing keeps residual forces low across the 090-size rotor, while the A-length construction keeps the footprint compact for enclosed machinery with limited installation space.
