Product Description:

The MDD025B-N-100-N2K-040FR0 is a compact synchronous motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for pairing with digital drive controllers, the unit supplies high-speed rotary motion to positioning axes and small spindle drives found in automated machinery. Its mechanical build follows the series’ standard housing scheme and employs standard rotor balancing, giving installers predictable mounting and vibration characteristics while omitting any internal blocking brake.

The motor seats against pilot surfaces with a centering diameter of 40 mm, ensuring repeatable coaxial alignment during assembly. At standstill it can deliver a continuous torque of 0.60 Nm, allowing light-duty holding or indexing without overheating. When energized by the matching drive, the rotor can reach a nominal speed of 10000 min⁻¹, a figure suited to fast tool changers or compact pumps that demand high peripheral velocity. All power and feedback conductors exit on the Right side of the stator, and a keyed Connector simplifies plug-in replacement without rewiring.

Position feedback is generated by an integrated absolute encoder whose single-turn data are interpreted through resolver feedback, giving the controller absolute position at power-up and fine incremental resolution during motion. The frame is classified as motor size 025 with length code B, so it fits tight envelopes while maintaining sufficient thermal mass. A plain shaft without a secondary end, combined with the absence of a shaft seal, reduces friction for high-speed service and permits direct coupling to precision gearboxes or collets. The shaft end follows the series’ standard geometry, easing interchangeability across machines.
