Product Description:

The MDD090B-N-040-N2M-110GR1 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed to operate with digital drive controllers, it converts electrical commands into controlled rotary motion for automated tooling, material-handling systems, and packaging axes. The motor is supplied in length code B within the 090 frame and uses a plain shaft interface, so rotary power is transferred directly to couplings or pulleys without intermediate gearing. This arrangement supports compact servo-driven machine axes that need repeatable motion and predictable response during frequent start-stop cycles.

The motor sustains 7.2 Nm of continuous torque at standstill, enabling static load support while the axis remains energized. During indexing moves it can reach a rated speed of 4000 rpm, matching the speed demands of light- to medium-inertia mechanisms. Machine integration is aided by a centering pilot of 110 mm that aligns the flange concentrically with attached frames and gearboxes. When power is removed, the integrated blocking brake supplies 6.5 Nm of holding torque to secure vertical or suspended loads until motion is re-enabled. The combination of standstill torque and braking support is useful where an axis must hold position between motion commands.

Position and velocity data are captured by an integrated multiturn absolute encoder and transmitted through digital servo feedback, allowing the drive to close precise control loops without external transducers. Absolute position information remains available over multiple revolutions, which helps the control system recover operating position after a restart. Power, brake, and feedback conductors terminate on the right side of the housing through a keyed connector, and the motor has a shaft seal to help protect the shaft area from contamination. The standard housing uses a single-ended shaft with no side-B extension, which helps keep the overall motor length compact.
