Product Description:

The MDD090A-N-040-N2L-130PR2 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for digital drive controllers, it supplies tightly regulated torque and speed to automated assemblies such as indexing tables, pick-and-place axes, and light conveyor stations. The motor’s electromechanical design lets control loops react quickly to command changes, supporting high cycle rates and repeatable positioning in industrial automation cells. This response supports smooth acceleration, controlled deceleration, and accurate settling during repeated motion sequences.

The unit sustains a nominal velocity of 4000 rpm, allowing fast travel between process points without overspeeding the rotor. When the shaft is locked, it can deliver a continuous torque of 3.7 Nm without exceeding its thermal limits, so the motor can maintain holding force during brief dwell periods. Position data are generated through digital servo feedback (DSF), enabling the controller to correct trajectory errors in real time. Cabling exits on the right side of the housing, which simplifies routing when several motors share a common cable channel. A plug-in connector interface provides a direct electrical connection without hard-wired terminations. Precise mechanical alignment is obtained with a centering diameter of 130 mm; this registers the motor flange to adjoining gearboxes or machine frames and helps minimize radial runout.

The integrated blocking brake provides 11.0 Nm of static holding capacity, preventing axis drift if power is removed during vertical or suspended duty. Torque is transmitted through a shaft with a keyway, giving positive drive engagement while limiting play during reversals. The frame uses the short A length in the 090 size and comes with a standard balance grade to keep vibration within normal operating limits. A shaft seal is installed at the output to retain lubricant and help shield the internal bearings from ambient dust or coolant spray. This arrangement supports operation in enclosed machinery where contamination control around the shaft opening is important.
