Product Description:

The MDD090B-N-040-N2M-110PL0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it delivers closed-loop rotational motion to conveyor segments, pick-and-place heads, and other axes that require fast indexing and repeatable positioning in factory automation lines. This motor is intended for applications where the drive must regulate both speed and position with a consistent response during frequent starts and stops. Feedback for speed and position loops is supplied through Digital servo feedback (DSF) with an integrated multi-turn absolute encoder, so the control system can track shaft angle across multiple revolutions.

At standstill, the motor can exert a continuous torque of 7.2 Nm, providing steady holding force without overheating when process loads remain stationary for extended periods. During normal operation it reaches a nominal speed of 4000 rpm, allowing the axis to achieve high surface velocity without requiring a change in the mechanical transmission. Precise mechanical centering is supported by a 110 mm locating diameter that helps align the motor housing with machine frames and mounting flanges. Motion is transferred through a shaft with a keyway, which supports secure coupling to pulleys, pinions, or similar drive elements.

Power and signal leads attach on the Left side through a single Connector, which keeps the interface compact and can simplify cable routing where space around the rear of the motor is limited. The motor is supplied without a blocking brake, so holding force during power-off conditions must come from drive torque or an external clamp. The length designation B places the unit in the middle build of the 090 frame, providing a moderate installation depth for machines that need more thermal mass than the shortest housing. The motor also uses standard balancing, a standard sealed housing, a fitted shaft seal, and no side-B shaft end.
