Product Description:

The MDD025A-N-100-N2G-040FC1 is a synchronous motor manufactured by Bosch Rexroth Indramat in the MDD Synchronous Motors series. It operates as the mechanical element in digital drive controller systems, supplying tightly regulated rotary motion for small actuators, pick-and-place heads, and light spindles in automated machinery. A standard housing and factory balancing allow direct mounting on a cabinet or machine frame without added vibration correction. This compact format suits small motion assemblies where low moving mass and quick response are important.

This model reaches a nominal speed of 10,000 rpm, enabling high cycle rates in tooling or indexing tasks. At standstill, it can deliver 0.33 Nm of continuous torque, so it can hold position under modest inertial loads while remaining within thermal limits. Position feedback is provided by resolver feedback, supplying rotor angle data for closed-loop control. Mechanical centering is aided by a 40 mm pilot diameter, which helps keep the motor aligned with the driven shaft. All power and feedback conductors exit on side A, which simplifies cable routing in tight multi-axis assemblies. The A length code indicates the shortest stator body offered for this frame size.

For power-off holding, an integrated blocking brake can exert 1.0 Nm of static torque to lock the axis when drive power is removed. The motor connects electrically through a connecting cable with a coupling unit, which supports orderly installation on linear slides or gantries. A plain shaft without a keyway supports clamp or collet couplings, and the design omits a shaft seal to reduce running friction where sealing is handled by the host machine. Size code 025 identifies the compact rotor diameter used in this family. The shaft end is provided only on the drive side, which helps reduce overhung mass during rapid reversals.
