Product Description:

The MDD090B-N-030-N2L-130GL2 is a synchronous AC motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Intended for pairing with digital drive controllers, the unit supplies precise closed-loop torque and speed for automated transfer lines, packaging axes, and material-handling units. An internal blocking brake holds stationary loads when power is removed, while feedback electronics report rotor position so the drive can execute point-to-point moves without overshoot. This configuration supports compact servo stations that require repeatable motion and stable stopping behavior during frequent start-and-stop cycles.

The pilot on the front flange has a centering diameter of 130 mm, enabling rigid alignment on gearboxes or mounting plates. During stall conditions, the windings deliver 7.2 Nm of continuous torque, giving the drive enough force for low-speed holding tasks without exceeding thermal limits. Rated mechanical speed reaches 3000 rpm, so the axis can achieve typical servo velocities while remaining within the motor’s operating range. Power and feedback conductors exit on the left side of the housing, and the integral round connector interface shortens cable routing and keeps the electrical connection compact at the motor.

The blocking brake supplies 11.0 Nm of static torque, preventing back-driving on vertical or otherwise gravitationally loaded axes whenever the servo is disabled. Rotor position is monitored through digital servo feedback (DSF), which transmits high-resolution signals to the controller for rapid current loops and precise synchronization with adjacent drives. The output side uses a plain shaft to mate with standard clamp couplings, which helps support accurate rotation in high-speed service. The housing is supplied with a shaft seal, shielding the bearing region from lubricants and airborne coolant during prolonged duty cycles. This layout supports operation in machinery where repeated motion and dependable position feedback are both required.
