Product Description:

The MDD090A-N-030-N2L-110PL0 synchronous motor is produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it converts electrical power into regulated rotary motion for pick-and-place units, tool changers, and conveyor axes in automated lines. The motor supports closed-loop control of torque and speed, which helps motion systems maintain repeatable positioning during frequent starts, stops, and direction changes. Its compact frame also helps conserve installation space in tightly packed machine layouts.

At standstill, it can deliver 3.7 Nm of continuous torque, allowing load-holding duty without excessive thermal rise. During motion, the rotor runs at a nominal speed of 3000 rpm, which suits many synchronous servo applications. Accurate mechanical alignment is aided by the 110 mm centering diameter, which provides a precise pilot fit in the mounting flange. Position feedback is supplied through integrated digital servo feedback (DSF), so the controller can monitor rotor position directly during operation. All power and signal conductors terminate in a single connector that is oriented to the left side of the stator housing, which can simplify cable routing in crowded cabinets.

Frame size 090 uses flange dimensions common to medium-duty drives, while the short A length keeps mass and inertia low for rapid indexing. The motor uses a shaft with a shaft seal, which helps protect the front bearings from coolant splash and light contamination. Its standard single-ended shaft is machined with a keyway for positive coupling to pulleys or gears. Because the unit is supplied without a blocking brake, static holding torque must come from the drive amplifier or an external clamp when the axis is stopped. Balancing and housing style are standard, making the motor suitable for general-purpose servo installations.
