Product Description:

The MDD090A-N-040-N2M-110PB2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It works with compatible digital drive controllers to provide controlled rotary motion for positioning axes, conveyors, and other automated machine functions on the factory floor. The motor uses a 090 frame size with an A-length housing, which helps it fit compact mechanical spaces in high-cycle production equipment. This format supports installations where accurate motion and a short overall motor length are both important.

The centering pilot measures 110 mm, providing a precise reference surface for concentric mounting on the machine. Power and feedback conductors exit on side B through a sealed connector, so cable routing stays away from the drive-end shaft and nearby couplings. The design does not use a second shaft on the rear side, leaving a single standard shaft end at the load side of the motor. During static operation, the motor can supply 3.7 Nm of continuous torque without thermal overload. Rotor position is monitored by an integrated multi-turn absolute encoder, which provides immediate absolute position data after power is restored and supports accurate interpolation during motion control.

An integrated blocking brake holds the shaft with 11.0 Nm of torque when power is removed, which is useful for axes that must remain in place at a stop. Under rated excitation, the rotor reaches 4000 rpm, and the motor works with digital servo feedback for closed-loop speed and position control. Torque is transmitted through a precision-ground keyway shaft, and the factory-installed shaft seal helps limit dust entry and oil leakage. The motor uses standard housing construction and standard balancing for general industrial service. Its A-length housing also keeps axial space requirements low in gantry, robot, and transfer-line joints.
