Product Description:

The MDD090A-N-040-N2M-130GL2 is an AC synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for use with digital drive controllers, the unit converts commanded current into precise rotor position and velocity for automated machinery. It incorporates an integrated multi-turn absolute encoder so the drive knows the true shaft position after power cycling, and the housing helps resist oil mist and dust in typical industrial environments.

Mechanical alignment is simplified by the 130 mm centering diameter and the standard balancing grade that keeps residual vibration low at operating speed. Electrical and feedback terminations are routed to the left side, and a sealed connector interface streamlines cable routing. At standstill, the motor supplies 3.7 Nm of continuous torque without exceeding thermal limits under rated conditions. When energized with the rated current, the rotor can reach 4000 rpm, giving high peripheral speed for rapid indexing tasks. Rotor position is returned through digital servo feedback, so the controller receives high-resolution position data and can correct load disturbances within each control cycle. The integrated blocking brake holds the shaft whenever power is removed, which helps keep vertical or suspended loads in place.

The brake provides 11.0 Nm of static holding torque to keep the axis fixed when the motor is not energized. Frame size 090 and length code A keep the housing compact for machines with limited installation space. The motor uses a plain shaft with a shaft seal to support direct coupling while helping limit the entry of fine particles. The shaft end is provided only on the drive side, so mechanical coupling is limited to that end of the motor. A standard aluminum housing and a molded connector complete the assembly while keeping the overall construction straightforward.
