Product Description:

The MDD025A-N-100-N2K-040FE0 is a synchronous servo unit manufactured by Bosch Rexroth Indramat for its MDD Synchronous Motors series. Engineered as a motor for digital drive controllers, it converts regulated current from the amplifier into precise rotary motion for light-duty axes where rapid acceleration and compact dimensions are critical within automated machinery.

At standstill the rotor develops a continuous torque of 0.33 Nm, while the windings permit operation up to a nominal speed of 10000 min⁻¹. The rotor is balanced to the manufacturer’s Standard grade to minimize vibration, and a centering diameter of 40 mm locates the housing accurately on mounting flanges. Power and feedback conductors exit on the left side through a connecting cable with coupling unit, simplifying routing in tight cabinets. Position data originates from an integrated absolute encoder, and resolver feedback signals are returned to the drive for commutation and loop closure.

The aluminum housing follows the series’ standard form factor and is supplied in length code A, matching compact machinery envelopes. Because the design is without a blocking brake, the axis must rely on drive-side torque or external clamps for static holding. A sealed bearing system is present, yet the motor is supplied without a shaft seal, so the front face should be protected from coolant spray. The rotor couples to the load through a plain shaft, and the opposite end is not machined, reflecting the standard configuration without a side-B shaft. With frame size 025, standard balancing, and left-hand power exit, the motor keeps inertial loads low during high-speed cycles.

Same-day shipping is available for urgent orders through Wake Industrial. Quotations issued for this motor stay firm for 30 days, simplifying budgeting cycles. Users may consult the free chat tool for general questions about type codes or resolver diagnostics.
