Product Description:

The MDD090B-N-040-N2L-110PB2 is a synchronous servo motor built by Bosch Rexroth Indramat for use with digital drive controllers in the MDD Synchronous Motors series. In closed-loop positioning and velocity control, it converts electrical power into precise rotary motion for automated machinery, conveyors, and tooling stations. The integrated blocking brake allows the rotor to hold position when power is removed, which is useful on vertical axes and on machines that must prevent drift during a stop. Its synchronous design also supports accurate motion response when paired with a compatible digital controller.

This model operates at a nominal speed of 4000 rpm, which supports fast axis movement in production equipment. At standstill, it can produce 7.2 Nm of continuous torque, so the motor can sustain a steady load during low-speed operation without excessive heat buildup. For stopping or holding, the blocking brake supplies up to 11.0 Nm of torque to keep the shaft from moving when drive power is removed. Position feedback is provided through digital servo feedback, allowing the controller to monitor rotor motion and correct command deviations in real time. The output shaft uses a keyway, which helps transfer torque securely to couplings, pulleys, or gear inputs.

A centering diameter of 110 mm helps align the motor accurately on the mounting face and supports repeatable installation. Power and feedback conductors exit on side B, which can simplify cable routing when the motor is installed near machine frames or guarding. A shaft seal limits the entry of dust and fluid around the output end, helping protect internal components during operation. Rotor mass distribution follows standard balancing, which supports smooth rotation and helps reduce vibration through the normal operating range. The B-length housing gives this motor variant a compact mechanical profile while preserving the mounting geometry used for this frame size.
