Product Description:

The MDD025C-N-100-N2G-040PC0 is a servo motor produced by Bosch Rexroth Indramat for use with digital drive controllers and belongs to the MDD Synchronous Motors series. As a compact size 25 unit, it delivers rapid rotational movement for positioning axes and small tooling spindles in automated machinery. This makes it suitable for compact automation equipment that requires quick response and stable speed control across repeated motion cycles. Its standard housing and integrated shaft seal permit installation in enclosures where moderate dust or fluid exposure is expected during normal industrial operation, and the motor is matched to control platforms that regulate torque and speed through high-frequency feedback.

The flange has a centering shoulder of 40 mm, allowing precise alignment with gearheads or mounting plates. At standstill, the motor can supply 0.90 Nm of continuous torque, so it can hold or slowly move a load without overheating under continuous conditions. Once energized, the rotor reaches a nominal speed of 10000 rpm, which suits applications that require high-frequency cycling or fine spindle work. Power and encoder leads exit on side A, and the motor uses a connecting cable with a coupling unit that mates directly with the drive cabinet. Balancing follows the standard grade, which helps limit residual vibration during high-speed operation.

Position information is returned through resolver feedback, so the controller receives rotor angle data during acceleration and speed changes. That feedback method also supports stable commutation at low speed and during rapid reversals. The motor is supplied without a blocking brake, so external clamping or drive torque must maintain position when power is removed. A single-ended keyway shaft transmits torque to couplings while helping prevent slip under start-stop duty. With frame designation 025 and length code C, the unit's low mass suits lightweight gantries, and its standard housing resists intrusion when the shaft seal is kept properly lubricated.
