Product Description:

The MDD025A-N-100-N2G-040MF1 is a permanent-magnet servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it is designed to supply finely regulated rotary motion to compact pick-and-place axes, light gantries, and other automation stations that demand high speed along with moderate holding capability. Its compact format suits space-limited machine sections where fast response and repeatable positioning are required. The permanent-magnet design also supports efficient torque production during frequent start-stop motion. This makes the motor a practical fit for short-travel axes that need precise acceleration and deceleration without a large housing.

This unit delivers a continuous standstill torque of 0.33 Nm, allowing the axis to maintain force without overheating during low-speed dwell periods. At its rated output, the rotor reaches 10000 min⁻¹, a velocity suitable for rapid indexing tasks where short cycle times are critical. Mechanical interfaces follow a centering diameter of 40 mm, so alignment with gearheads or flange plates remains repeatable. The motor has a size of 025, and its overall stack length corresponds to code A, yielding a low-mass rotor that accelerates quickly. Dynamic behavior is supported by standard balancing, which keeps residual vibration forces within limits required for precision drive trains.

An integrated blocking brake supplies a holding torque of 1.0 Nm, enabling the shaft to stay fixed during power-off or vertical load conditions. Position data are returned through resolver feedback, so the controller receives absolute rotor angle even during rapid reversals. All power and sensor leads exit to the right, matching machines that route conduits on that side, while the connecting cable terminates in a coupling unit for quick changes without tools. The shaft is machined with a keyway to transmit torque without slip, and the opposite end remains closed because the design is standard without a side-B extension. There is no shaft seal, so the motor must be installed in enclosures where contaminant ingress is already controlled, and the standard housing profile allows direct mounting to modular plates or small bracket frames.
