Product Description:

The MDD090B-N-040-N2L-130GL1 synchronous motor is manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. In a closed-loop drive system, it converts electrical power from a compatible digital drive controller into rotational motion, enabling precision positioning or continuous velocity control on automated axes. Its brushless design with integrated position feedback allows the controller to regulate current accurately, keeping the motor aligned with programmed motion profiles in assembly robots, conveyors, and machine tools. The feedback system supports stable commutation and position correction during changing loads.

The motor can deliver a continuous standstill torque of 7.2 Nm, which is the steady load it can support without overheating. The integrated blocking brake provides a static holding torque of 6.5 Nm, helping prevent axis drift during power-off or emergency-stop conditions. The rated mechanical speed reaches 4000 rpm, so the connected gearbox or belt stage must keep peripheral velocity within that limit. A 130 mm centering diameter aligns the motor to the machine frame and helps reduce shaft runout. Command and feedback data are exchanged through the built-in digital servo feedback interface, allowing the controller to close both current and position loops with high resolution.

The motor belongs to size 090, which gives it a frame cross-section compatible with other drives in the series, and it uses length code B for a medium body length. Power and feedback connectors exit in a left-hand connector orientation, so cable routing can be planned without additional elbows. That arrangement can reduce cable strain where nearby machine structures limit bend space near the motor. The rotor uses a plain shaft that accepts clamp couplings or pulleys, and a shaft seal is installed to limit the ingress of coolant or dust. Standard dynamic balancing helps keep vibration within ISO limits, and the housing uses the series' standard convection-cooled design.
