Product Description:

The MDD025A-N-100-N2K-040PC0 is a synchronous servo unit produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed to pair with digital drive controllers, it delivers rapid positioning and speed regulation on pick-and-place axes, small spindles, or laboratory automation stages where compact dimensions and high rotational velocity are critical.

A continuous stall torque of 0.33 Nm lets the motor hold light loads without overheating, while the rated speed of 10000 min⁻¹ supports swift indexing cycles. Mechanical alignment to gearboxes or mounting fixtures is simplified by a centering diameter of 40 mm, keeping radial run-out low. The compact frame is denoted by motor size 025, and the shortest case length, code A, minimizes footprint in dense multi-axis assemblies. Standard dynamic balancing further reduces vibration, enhancing bearing life and feedback accuracy at high rpm.

Cables exit on the machine side identified as Side A, and power is supplied through a connecting cable with coupling unit that locks without tools. An integrated absolute encoder delivers position data immediately after power-up, while complementary resolver feedback supplies robust velocity information for the drive controller. The rotor includes a keyway shaft, and a shaft seal is fitted to limit ingress of cutting fluids or dust. A standard housing, standard shaft end on side A only, and the absence of a blocking brake keep weight low and inertia minimal, matching the motor’s high-speed profile.
