Product Description:

The MDD090C-N-030-N5M-110PB0 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed to operate with digital drive controllers, it converts three-phase electrical power into precise rotary motion for indexing tables, pick-and-place arms, and light conveyor drives in automated production lines. Its mechanical format follows the 090 frame size so the unit fits common machine layouts without custom adapter plates, and an integral flange allows direct mounting to gearboxes or belt pulleys.

The motor’s flange centers on a 110 mm pilot, providing repeatable alignment with couplings and housings. All electrical terminations are located on Side B, and the motor uses a single circular connector for power and feedback connections. At standstill the stator delivers a continuous torque of 10.4 Nm, enabling the axis to hold static loads such as vertical tooling without overheating. When driven from a matched inverter, the rotor can sustain a nominal speed of 3000 rpm, giving a wide operating range for packaging or handling duties. An oil-resistant shaft seal surrounds the keyed output shaft, helping limit the ingress of coolant and fine dust. Position and speed data are returned to the controller through the digital servo feedback channel.

Dynamic accuracy is assisted by the rotor being balanced to the Standard grade, which keeps vibration within ISO limits at full speed. The electromagnetic stack with the C length code offers additional active iron compared with shorter variants, improving torque density without a major increase in footprint. Absolute position tracking is supplied by an onboard integrated multiturn absolute encoder, eliminating homing cycles after each power loss. For machinery that already employs mechanical clamps or dynamic holding by the drive, the motor is delivered without a blocking brake, reducing mass and simplifying the connector layout. The shaft uses a keyway, and the wiring arrangement uses a connector-based interface.
