Product Description:

The MDD090B-N-030-N2M-110PA0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is used with digital drive controllers to convert regulated current into torque while returning rotor position data for closed-loop motion control. This arrangement supports accurate speed control, positioning, and repeatable response in automated production equipment. The B length code and 090 frame size place the motor in a compact mid-range housing that fits many multi-axis machine layouts without requiring an oversized mounting envelope.

A nominal speed of 3000 rpm gives the motor a high operating speed for direct-drive or geared axes. At standstill, it can sustain 7.2 Nm of continuous torque without exceeding thermal limits, which supports steady holding force during short dwell periods when controlled by the drive. The mounting flange has a centering recess of 110 mm for accurate alignment with the driven mechanics. Power, feedback, and auxiliary conductors exit on Side A, keeping cable routing on one face of the motor. Position data is provided by an integrated multi-turn absolute encoder, so the controller can retain shaft position information after power is restored.

Signal transmission to the controller uses digital servo feedback (DSF), which helps avoid analog drift and supports stable communication between the motor and drive. The motor is supplied without a blocking brake, so applications with suspended or vertical loads need a separate holding method when power is removed. A fitted shaft seal helps reduce the entry of contaminants and limits lubricant escape around the keyway shaft. The standard housing, standard dynamic balancing, single connector arrangement, and the lack of a side-B shaft end keep the mechanical layout straightforward for established MDD installations.
