Product Description:

The MDD090A-N-030-N2M-130GL0 synchronous motor is produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it supplies rotary motion to axes that depend on tight position loops in automated machinery and packaging lines. In closed-loop operation, the paired controller adjusts motor current to keep speed and position aligned with the commanded motion profile even when load conditions change. That makes the unit suitable for positioning tasks that require repeatable starts, stops, and speed changes over frequent production cycles. The motor uses the standard housing style of the series and standard rotor balancing to keep vibration controlled during normal operation, while a shaft seal helps protect the internal bearing set from oil or dust intrusion.

For mechanical integration, the motor has a centering diameter of 130 mm, allowing accurate location in flange mounts without added shims. Power and feedback cabling enter from the left side through a keyed connector, which supports orderly routing in multi-axis cabinets. During stall duty, the frame can deliver 3.7 Nm of continuous torque, and under rated excitation the rotor can reach 3000 rpm for medium-speed conveyor or transfer tasks. The combination of size 090 and length code A keeps the body compact, which helps when the motor must fit into limited installation space and maintain responsive axis behavior.

Position data is generated by an Integrated multiturn absolute encoder, which returns both direction and rotation count to the drive through Digital servo feedback (DSF). The feedback system gives the controller the information needed for commutation and precise motion regulation across the operating range. This arrangement supports startup without homing on applications where the axis position must remain known after power cycling. Because the motor is supplied without a blocking brake, static load holding must be handled by the drive or by external mechanical retention when power is removed. The output uses a plain shaft in a standard single-ended arrangement on side A, so couplings or pulleys can be mounted at the drive end while the opposite side remains closed.
