Product Description:

The MDD090B-N-030-N2L-130GB2 is a synchronous servo unit produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded current into regulated rotary motion for packaging lines, pick-and-place gantries, and compact machining centers. Integrated permanent magnets, a sealed housing, and internal feedback circuitry enable precise speed control without requiring an external encoder assembly. This arrangement supports repeatable positioning and stable axis movement in compact multi-axis automation equipment where space and response are both important.

At standstill, the motor can deliver 7.2 Nm of continuous torque, allowing stable holding without thermal overload. During motion, it sustains a nominal speed of 3000 rpm, balancing torque output with rotor dynamics. Mechanical integration uses a centering diameter of 130 mm, which aligns the stator housing with the machine frame. Position data is returned through digital servo feedback, allowing the controller to close the speed and position loops with high resolution. All power and signal conductors exit on side B, and a circular connector simplifies cable attachment. The motor uses size 090 with length code B, and the standard housing dissipates heat without auxiliary cooling.

A blocking brake is fitted to arrest the shaft when power is removed, and it can exert 11.0 Nm of holding torque to secure loads. Rotor balance follows standard balancing, which helps keep vibration within normal limits at rated speed. Drive coupling uses a plain shaft that omits keys and supports friction-fit hubs. Contaminant ingress is limited by a shaft seal, permitting service in environments with light oil mist. The motor has a single shaft end on the drive side only, so there is no rear extension for auxiliary couplings. That layout leaves the rear of the motor clear in installations where access space is limited.
