Product Description:

The MDD025A-N-100-N2K-040FR0 is a compact synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed to pair with digital drive controllers, it delivers precise rotary motion for pick-and-place heads, lightweight gantries, and other high-speed axes where low inertia and tight velocity regulation are required.

At standstill the motor can provide a continuous torque of 0.33 Nm, allowing stable holding forces on delicate mechanisms while minimizing heat rise. During operation it reaches a nominal speed of 10000 min⁻¹, so fast index cycles are possible without gearing. Wiring is simplified because power and feedback connectors exit on the Right side of the housing, keeping cable tracks short in linear stages. Position data is returned through resolver feedback, giving robust angular information even under electrical noise. Accurate mechanical alignment is helped by a centering diameter of 40 mm, matching common servo flanges used in compact machinery.

For fine absolute positioning the unit integrates an integrated absolute encoder that eliminates homing moves after power-up. A Plain shaft transmits torque without keyways, reducing backlash in precision couplings, and the construction follows length code A within motor size 025, resulting in minimal mass and short axial dimensions. The motor is built without a blocking brake and without a shaft seal, choices that further reduce inertia and friction for dynamic duty cycles.

Wake Industrial offers same-day shipping options when production schedules are tight, supplies a 1-year warranty on every unit, and provides a free chat tool for general questions about type codes or fault indications.
