MDD025A-N-100-N2G-040ME1
The MDD025A-N-100-N2G-040ME1 is a compact synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it integrates into closed-loop positioning axes where fast response and repeatable accuracy are required. The frame follows size 025 and length code A, giving a short body that fits tightly packed machinery while still accepting a standard mounting flange. That compact layout also helps when adjacent components leave limited installation space around the axis.
At standstill, the motor delivers a continuous torque of 0.33 Nm, allowing it to hold loads without overheating. A blocking brake adds 1.0 Nm of static torque so the shaft can remain still when power is removed. The rotor is rated for 10,000 rpm, supporting high linear speeds when coupled to ball screws or timing belts. Position data is generated by resolver feedback, which supplies analog sine-cosine signals that remain reliable under electrical noise and high rotational speed. Precise concentricity is maintained by a 40 mm centering diameter, which helps align the motor accurately with gearheads or couplers. All power and signal terminations exit on the left side so cabinet wiring can be routed away from moving members.
The rotor uses standard balancing, which limits vibration even at maximum speed. The winding leads arrive on a connecting cable with a coupling unit, providing a straight plug-in interface to the drive. Torque is transmitted through a shaft machined with a keyway, while the shaft journal is supplied without a shaft seal, which reduces running friction when fluid contamination is not a concern. The cast-aluminum housing has the standard finish for general indoor environments. The motor uses a standard shaft end on side A only, and the absence of a side B extension simplifies coupling to single-ended loads.
