Product Description:

The MDD025A-N-100-N2G-040FB1 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers where precise rotational movement is required to position light loads, actuate small transfer axes, or spin miniature tool spindles. A plain shaft simplifies coupling to gearheads or pulleys, and the integrated brake helps hold axis position when control power is removed. Its compact format is useful where surrounding mechanisms leave little room for larger motor housings.

The motor has a nominal speed of 10,000 rpm, which supports rapid indexing cycles in high-throughput automation. During dwell periods, it can supply 0.33 Nm of continuous torque at standstill, giving enough holding force to counter light process loads without overheating. Electrical and feedback cabling exits on Side B, which can help keep cables away from the working end of the axis. A single plug-in connector supports a clean electrical interface, and the centering flange measures 40 mm in diameter for accurate radial alignment against a machine plate or adapter. High rated speed and compact mounting make the motor useful on short-stroke axes and small rotary units that need fast response.

The blocking brake delivers up to 1.0 Nm of static torque, which helps secure vertical or cantilevered axes until commanded release. Position and velocity loops use internal resolver feedback, providing continuous angle information even during high-speed rotation. Rotor and coupling components use a Standard balancing grade to limit vibration during normal operation. The housing is supplied without a shaft seal, so the motor should be installed in a protected environment or paired with an external sealing method where fluids or heavy contamination are present. This arrangement is suitable for enclosed machinery where the motor is shielded from washdown and direct debris exposure.
