Product Description:

The MDD090B-N-030-N2M-130PA0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it supplies closed-loop rotary motion for automated axes, pick-and-place modules, and packaging machinery. By pairing permanent-magnet excitation with electronic commutation, the unit delivers precise speed and torque regulation, making it suitable wherever compact electric actuators must respond quickly to drive commands issued by CNC- or PLC-based systems.

At a nominal speed of 3000 rpm, the rotor reaches its synchronous operating velocity under rated load, letting the controller position the axis without overshoot. When stopped but energized, the motor can exert 7.2 Nm of continuous torque, so clamping tables or indexers remain fixed against process forces. A centering diameter of 130 mm simplifies alignment on gearbox flanges, and the shaft is machined with a keyway to help prevent coupler slip during acceleration. The standard shaft end is supplied without a side-B extension, which simplifies coupling to belt pulleys. Position data are returned through an integrated multi-turn absolute encoder, whose magnetic track records multiple revolutions and allows the drive to recover the exact rotor angle after power is restored.

Feedback signals leave the housing through a molded connector as digital servo feedback, and all power and signal wiring exits on Side A, which can simplify cable routing when drives are mounted below the motor. Because the rotor is supplied without a holding brake, power-off retention must be provided by drive torque or a mechanical lock. A shaft seal helps block oil or coolant from entering the bearings, while standard balancing keeps vibration within ISO limits. The size 090 stator frame and the B length code give the motor a compact profile, and the standard housing with a connector interface supports consistent installation across the series.
