Product Description:

The MDD025C-N-100-N2G-040GL1 is an AC synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for pairing with digital drive controllers, it converts controlled current into rapid rotation for indexing tables and light-duty pick-and-place axes. The motor uses the longer C length stator body inside a standard housing, maintains standard dynamic balancing to minimize vibration, and incorporates a blocking holding brake that secures the load when power is removed. A single-ended shaft is provided for coupling to belts or rigid sleeves.

At a maximum commanded velocity of 10,000 rpm, the motor suits applications that demand high spindle or feeder speeds without gear reduction. Its continuous torque at standstill is 0.90 Nm, allowing the axis to hold light loads in position while stalled without exceeding rated copper losses. For short duty peaks, the integrated brake supplies 1.0 Nm of mechanical holding torque, maintaining position during emergency stops or power loss. Size code 025 indicates the overall stator diameter, and the centering pilot of 40 mm simplifies concentric mounting on precision adapter plates. Position feedback is delivered through resolver feedback, providing rotor angle information to the drive for closed-loop vector control even during low-speed operation.

Electrical terminations exit toward the left, and a keyed circular connector mates with the drive harness so installation can be completed without hard-wiring. The motor is sealed at the front bearing with a shaft seal, improving ingress protection when coolant or dust is present. A plain shaft profile eliminates keyways to reduce stress. The design omits a side-B extension, so couplings are mounted only on the primary end. This arrangement keeps the non-drive end clear and supports straightforward coupling on the primary shaft end.
