MDD025C-N-100-N2G-040MC0
The MDD025C-N-100-N2G-040MC0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it converts electrical power into controlled rotary motion for compact automation axes that require high speed and accurate response. Because it is a synchronous servo motor, it is suited to applications that need repeatable position control rather than simple fixed-speed rotation. Its compact form and standard balancing allow direct machine mounting without added counterweights for vibration damping.
This model develops a continuous standstill torque of 0.90 Nm, which provides constant torque when the shaft is energized but not rotating. During operation it can reach a nominal speed of 10000 rpm, supporting fast position cycles in pick-and-place stages or spindle drives. Accurate mounting is aided by a centering diameter of 40 mm, and electrical power reaches the stator through a connecting cable with coupling unit routed on side A, which keeps cable access on one face of the machine. Rotor position is returned to the controller by resolver feedback, so the drive receives a stable angle signal across the full mechanical revolution and remains resistant to electrical noise.
The mechanical interface uses a shaft with a keyway and is supplied without a shaft seal, so the surrounding machine should protect the motor if liquid or heavy contamination is present. The shaft is a standard single-ended design, which omits a secondary shaft on side B and helps keep the motor short. The unit is delivered without a blocking brake, so axes that need load holding at standstill must rely on drive torque or an external clamp. The resolver electronics and windings are enclosed in the standard housing, which protects internal parts in typical industrial service.
