Product Description:

The MDD090C-N-040-N2M-130PB1 is a synchronous servo motor supplied by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for direct use with digital drive controllers, it converts commanded current into precise rotary motion for positioning tasks on gantry axes, feed drives, and material-handling stations in industrial automation lines. The motor is intended for closed-loop motion, so the connected drive can regulate speed and position with good repeatability. This arrangement supports axes that start and stop frequently under changing load conditions. It also fits applications where smooth speed regulation is as important as final position accuracy. Its housing follows the established series geometry for mechanical mounting and electrical connection.

The motor delivers a continuous standstill torque of 10.4 Nm, permitting load holding without excessive heating, and its shaft can reach a rated speed of 4000 rpm during continuous duty. A blocking brake applies up to 6.5 Nm of static torque to secure the axis when power is removed. Mechanical centering is provided by a 130 mm pilot diameter, while all power and feedback conductors exit on side B through the housing connector. This cable exit can simplify routing when the opposite end of the motor faces machine tooling or a gearbox. Standard balancing helps limit vibration, and an integral shaft seal protects the internal bearings from coolant or dust during normal machine operation.

Position data comes from an integrated multi-turn absolute encoder and is sent to the drive as digital servo feedback, enabling homing-free restarts and accurate velocity control. The encoder retains position across multiple revolutions, which helps the control system recover axis location after power returns. The output uses a keyway profile for torque transmission, and the motor uses motor length code C to balance torque capacity against overall mass in the 090 frame size. The standard housing and sealed connector interface support straightforward installation in enclosed machinery.
