Product Description:

The MDD090B-N-030-N2L-130GR1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. This brushless motor works with digital drive controllers to provide controlled torque and speed in machining centers, pick-and-place gantries, and forming equipment. Hall sensors and a resolver are not used; instead, integrated digital feedback lets the controller correct position and velocity in real time so the motor can maintain commanded motion profiles under changing loads. Its feedback arrangement supports repeatable starts, stops, and speed changes during automated cycles.

At its rated operating point, the rotor reaches a nominal speed of 3000 rpm, which suits mid-range axis duties. When the shaft is locked, the electromagnetic system can deliver a continuous stall torque of 7.2 Nm, so the axis can support static loads without overheating. A factory-mounted blocking brake adds 6.5 Nm of holding torque to help prevent back-driving during power loss. This brake arrangement also supports applications that must hold position when drive power is removed. Position data is returned through digital servo feedback (DSF), and the electrical and encoder connections exit on the right side of the housing for straightforward cable routing inside multi-axis cabinets.

The motor uses standard balancing, which helps limit residual vibration when it is coupled to precision gearboxes. A centering pilot of 130 mm aligns the flange, and the power leads attach through a keyed connector. The output uses a plain shaft, and a fitted shaft seal helps block lubricant loss and coolant entry during washdown cycles. The shaft seal is useful where coolant splash or light contamination is present around the drive end. Size code 090 and length code B identify the active magnetic stack and support predictable mass and moment of inertia for load matching.
