Product Description:

The MDD090B-N-030-N2M-110GR2 is a brushless AC servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts electrical power into precise rotary motion for automated transfer lines, indexing tables, and packaging spindles. Permanent-magnet excitation and electronic commutation support accurate positioning while keeping the frame compact for machine-side or cabinet installation. This arrangement also supports responsive speed control in applications that require repeatable motion over frequent start and stop cycles.

At standstill, the rotor delivers a continuous torque of 7.2 Nm, so stations can hold loads without overheating during normal operation. Once commanded, it reaches a nominal speed of 3000 rpm, matching common gear ratios used in material-handling equipment. A blocking brake rated at 11.0 Nm engages automatically on power loss, which helps prevent vertical axes from drifting or settling. Position recognition is supplied by an integrated multiturn absolute encoder that retains revolution data after shutdown. Dynamic balancing is standard, the cast-aluminum housing uses a standard design, and both power and feedback leads exit to the right through a sealed connector interface that supports orderly cable routing.

The flange includes a centering recess of 110 mm to register the motor precisely against gearboxes or end plates. Encoder signals leave the unit as digital servo feedback, allowing the associated drive to process position and speed data directly for closed-loop control. A plain shaft helps provide a simple output interface, and a shaft seal helps protect the front bearing area from fluid ingress. Dimensional coding follows size 090 with length code B, placing the motor in the corresponding frame envelope of the series. The single-ended shaft arrangement reduces mass at side B while maintaining stable support for smooth rotation.
