Product Description:

The MDD090C-N-030-N2M-130GB1 is an AC synchronous servo motor built by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. It is intended for use with compatible digital drive controllers where precise speed and position control are required. By delivering regulated torque without mechanical backlash, the motor supports coordinated axis motion in automated packaging units, pick-and-place modules, and other industrial handling systems. Closed-loop operation helps the axis maintain consistent motion during load changes and frequent start-stop cycles. This makes the motor suitable for applications that depend on repeatable indexing, smooth interpolation, and accurate positioning over long production runs.

The centering pilot measures 130 mm, providing a rigid interface that minimizes concentricity error between the motor flange and the machine frame. Power and feedback conductors exit at the rear because the connection hardware is mounted on Side B, which can simplify cable routing inside cabinets and machine bases. At standstill, the motor can generate a continuous torque of 10.4 Nm, allowing it to hold or slowly drive loads without exceeding thermal limits. During normal operation, the rotor reaches a nominal speed of 3000 rpm, matching drive frequencies used in standard servo loops. Position information is obtained from an integrated feedback package that combines an integrated multiturn absolute encoder with digital servo feedback, so the controller receives absolute shaft angle across multiple revolutions without requiring homing after every restart.

The motor includes a holding brake rated at 6.5 Nm, adding mechanical retention when the axis must remain fixed after power is removed. A plain shaft eliminates keyways, which reduces stress concentrations and suits clamp-style couplings used on high-precision gearheads. To protect the front bearing from lubricants and dust, the design includes a shaft seal, allowing installation in environments where fine particulate or light fluid spray is present.
