Product Description:

The MDD090C-N-030-N2M-110PB0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for digital drive controllers, it serves as the rotary actuator that follows commanded velocity and position profiles in automated production lines. The model combines the 090 frame size with a C length code to provide the torque and speed needed for medium-duty axes while keeping the installation envelope compact for multi-axis machining centers and material-handling stations.

Mechanically, the motor delivers a continuous standstill torque of 10.4 Nm, allowing static load support without exceeding its thermal envelope. It reaches a nominal speed of 3000 rpm, so the drive can maintain linear feed rates that match typical tooling requirements. The centering diameter of 110 mm matches common flange interfaces and works with the standard balancing grade to minimize vibration. With the size code 090 and the C length category, the housing remains standard and does not require special spacers. Rotor position is measured by an integrated multi-turn absolute encoder, providing absolute position data over multiple revolutions for drive synchronization. A keyed shaft is used for power transmission.

Electrical integration is straightforward because the power and feedback connectors are mounted on Side B of the stator and use a single circular connector style. Feedback signals are transmitted as Digital servo feedback (DSF), enabling high-resolution velocity loops inside the drive controller. The rotating shaft is protected with a shaft seal, which helps block lubricant migration. The motor is supplied without a blocking brake, so external clamping methods must be used when power-off holding is required. The shaft ends in a keyway, and the opposite shaft end is omitted, allowing the motor to fit flush against gear stages or couplings.
