Product Description:

The MDD090B-N-030-N2M-110GB0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it delivers closed-loop rotary motion to machine tools, printing lines, and automated handlers where repeatable positioning is required. The unit uses frame size 090 and length code B, which fit medium-power axes without changing cabinet depth or common mounting patterns. This type of motor is commonly paired with servo amplifiers that correct commanded motion by continuously comparing target values with measured rotor position.

The rotor is trimmed to a standard balancing grade, so vibration stays within ISO limits at rated speed. A centering diameter of 110 mm aligns the flange precisely on the machine face, while the power and feedback plugs exit on side B so cables clear adjacent equipment. A sealed circular connector carries both motor phases and control conductors through one compact interface. At standstill the motor produces 7.2 Nm of continuous torque, and during motion it reaches a nominal speed of 3000 rpm, which suits drives that operate at 300 Hz electrical frequency. Position data come from an integrated multi-turn absolute encoder, so the controller can retain absolute position information after power is removed.

The feedback signal is transmitted as Digital servo feedback (DSF), giving the controller fine resolution for contouring tasks. A plain shaft couples directly to bellows or clamp hubs, and a design with a shaft seal helps keep coolant and dust away from the bearing set. Because the motor is supplied without a blocking brake, external clamping or drive torque must hold vertical loads when power is off. The housing uses the standard ribbed style to support surface cooling without auxiliary fans, and the non-drive-end shaft extension is omitted to save space in compact machine layouts and tight gantry wrists.
