Product Description:

The MDD025C-N-100-N2K-040MB1 is a small synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended to pair with digital drive controllers in light-duty positioning axes, delivering precise rotary motion within industrial automation cells. Standard rotor balancing, a keyed shaft end, and a single plug-style power/feedback connector simplify installation while minimizing vibration during high-speed service.

This motor achieves a nominal mechanical speed of 10000 min⁻¹, allowing compact machines to run high-speed duty cycles without gearbox multiplication. At standstill it can supply 0.90 Nm of continuous torque, sufficient for maintaining position against modest process loads, while its blocking brake can hold up to 1.0 Nm when power is removed. Frame details influence integration: the unit belongs to size code 025, and its body length is designated as C, so envelope dimensions remain small for cramped cabinets. A centering pilot of 40 mm simplifies concentric alignment with gearheads or couplings and keeps radial run-out under control during rapid accelerations.

Electrical and feedback conductors exit on Side B, which permits cable routing away from the load side of the shaft. Rotor position is reported through resolver feedback, giving analog sine-cosine signals that withstand electrical noise and high temperatures better than digital encoders. Because the front output shaft is supplied without a shaft seal, users should avoid wash-down environments or fit external sealing if fluids or dust are present. Together, these construction choices let the motor occupy tight spaces, support straightforward cabling, and maintain reliable commutation data for servo drives without increasing overall inertia.
