Product Description:

The MDD090B-N-040-N2M-130PB0 is a size 090 synchronous AC servo motor built by Bosch Rexroth Indramat and placed within the MDD Synchronous Motors series. Supplied as a motor for digital drive controllers, the unit converts electrical command signals into controlled shaft motion for positioning, conveying, or tooling in automated machinery. Electrical power and feedback reach the unit through a connector interface, so removal requires no hard-wired terminations. Its synchronous design supports precise response to drive commands during acceleration, holding, and repeatable positioning cycles.

Bearing a centering diameter of 130 mm, the standard housing aligns easily with machine flanges while maintaining shaft concentricity. The rotor is balanced to a standard grade, which helps limit vibration across the working range. Under static load, the motor can deliver 7.2 Nm of continuous torque, and its nominal operating speed is 4000 rpm. Position data are produced by an integrated multiturn absolute encoder, and motion signals are exchanged with drives over digital servo feedback channels, giving the controller exact rotor state at every sample. This combination allows the drive to monitor position and speed without relying on a separate external feedback device.

The shaft features a keyway profile and is protected by a shaft seal that limits lubricant escape and airborne contamination. Power and feedback plugs are oriented on side B of the frame, an arrangement that keeps cable bends short when the motor rear faces the control cabinet. Because the design is supplied without a blocking brake, any static load retention during power loss must be provided by external devices. The shaft is present only on the drive side, so there is no shaft extension on the rear of the motor. This single-ended layout leaves the rear housing available for connectors and cable exit.
