Product Description:

The MDD090B-N-040-N2L-130PB0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed to pair with digital drive controllers, the unit converts commanded current into precise mechanical rotation for industrial positioning and velocity tasks. Its compact frame and standardized electrical interface allow use in multi-axis packaging machinery, small machining centers, and material-handling axes where repeatable speed regulation and rapid reversals are required. Because the motor is intended for servo operation, it can respond quickly to changing commands from the drive during synchronized machine cycles.

The motor’s centering shoulder measures 130 mm, establishing the reference diameter that aligns the housing with the machine flange and helps keep runout low during installation. Power and feedback conductors exit on side B, which can simplify cable routing when the motor is mounted with its shaft facing forward. A single industrial connector carries both motor phases and encoder signals, so wiring can be completed without opening the enclosure. This combined connection style also reduces the number of external cable entry points on the housing. During continuous stall conditions, the motor delivers 7.2 Nm of torque, supporting static loads or slow-speed holding when adequate cooling airflow is available. The unit is supplied without a blocking brake, so vertical axes require drive torque or a separate mechanical holding device when power is removed.

Rotor position is reported through digital servo feedback (DSF), enabling the controller to close high-resolution loops for commutation and stiffness. Under rated conditions, the shaft reaches 4000 rpm, which supports high traverse rates while staying within the intended operating range of the motor. Torque is transmitted through a keyway, which helps prevent slippage when pulleys or couplings are clamped to the shaft. The front bearing region is protected with a shaft seal, reducing the ingress of coolant splash or dust so the lubricants retain viscosity over long duty cycles.
