Product Description:

The MDD090A-N-040-N2L-110PB0 is a compact AC synchronous servo motor built by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. Delivered as a motor for digital drive controllers, it converts commanded current from an inverter into controlled rotary motion. This supports positioning tables, pick-and-place arms, spindle auxiliaries, and other repeatable axis tasks in automated production equipment. Its synchronous design supports accurate speed regulation and repeatable motion during indexing, feeding, and similar axis movements.

At rated excitation the motor can furnish 3.7 Nm of continuous stall torque, allowing stable holding or slow-speed feed operations without overheating. When the load is released, the rotor reaches a base speed of 4000 rpm, giving adequate headroom for rapid traverse tasks. The rotor uses standard balancing, which keeps vibration within limits for coupled gearheads. Accurate mechanical centering is achieved with a mounting pilot of 110 mm, while the frame footprint follows size 090 and the short A length code to minimize axial space. Position information is transmitted to the drive through digital servo feedback, enabling fine current vector control and quick disturbance correction during motion changes.

Cabling enters from the rear because the power and feedback sockets occupy the Side B face and use a sealed connector interface. Torque is delivered through a cylindrical shaft machined with a keyway; this standard end lacks an opposing stub on side B, which simplifies coupling alignment. A durable shaft seal protects the internal bearings from cutting fluid or dust migration. The design is supplied without a blocking brake, so holding torque must be generated electrically or through external clamping devices. The housing follows the standard enclosure style used in the series and keeps the motor layout compact for enclosed machine spaces.
