Product Description:

The MDD025A-N-100-N2K-040MD1 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 converts commanded current into rapid rotary motion for small automation axes. High dynamic response and integrated position feedback make the unit suitable for precise speed regulation, pick-and-place heads, light assembly tooling, and other compact motion systems. Its small format supports direct installation in compact machinery where mounting space is limited and fast acceleration is required.

At a nominal speed of 10000 rpm, the rotor can follow fast command changes while remaining within the thermal limits of the A-length frame. When held motionless, it produces 0.33 Nm of continuous torque, which suits light linear stages and indexing tables. A blocking brake rated at 1.0 Nm secures the load during power-off events or emergency stops. Power and signal conductors exit on side B, which helps route moving cables away from nearby sensors. Precise concentricity comes from a 40 mm centering diameter that fits common machine flanges. Commutation and closed-loop control rely on resolver feedback, and an integrated absolute encoder relays multi-turn position data to the controller.

The motor uses standard balancing to limit vibration without external counterweights. Field wiring is simplified by a connecting cable with coupling unit, which allows the motor lead set to be separated quickly when the axis is removed from the machine. The output shaft uses a keyway interface, and the opposite end has no shaft extension. Because the motor is supplied without a shaft seal, it is best suited for clean installation areas or applications that use external sealing at the driven element. A standard housing with motor size 025 and length code A keeps the overall envelope small for crowded mounting positions inside small enclosures.
