Product Description:

The MDD090B-N-040-N2L-130PR0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it supplies commanded rotary motion to automated equipment that relies on precise speed and position loops. Integrated with a compatible drive, it converts electrical current into controlled mechanical output for indexing tables, packaging machinery, and material-handling axes. Its synchronous operating behavior supports repeatable motion where an axis must accelerate, decelerate, and settle with low speed error across repeated production cycles. This makes the motor suitable for machinery that depends on consistent cycle timing and coordinated axis movement.

At its rated point, the motor delivers a nominal speed of 4000 rpm, giving fast surface velocities on compact tooling. Continuous torque available at standstill is 7.2 Nm, allowing the axis to resist load during short dwell periods. Rotor position is reported through digital servo feedback, so the controller can maintain accurate current regulation and stable path tracking. The feedback channel also lets the paired controller monitor rotor movement continuously, which improves low-speed smoothness and supports accurate positioning after direction changes. Mechanical vibration is minimized by standard balancing, and installation repeatability is supported by a centering diameter of 130 mm, which helps align the motor concentrically with adjoining machine parts.

Power and feedback enter through a sealed connector, and all terminations face one side because of the right connection direction, which can simplify cable routing in confined machine spaces. A radial shaft seal helps protect the internal bearings from dust and light spray during normal operation. Torque is transmitted through a keyway, which helps prevent shaft slippage when pulleys or couplings are subjected to repeated load changes. Sealing and one-sided cable entry can also reduce interference with nearby guards, frames, or gearbox housings when the motor is installed in a tight envelope. Because the unit is supplied without a blocking brake, vertical or inclined axes must rely on drive-applied holding torque or a separate mechanical retaining device when power is removed.
