MDD025B-N-100-N2G-040FF1
The MDD025B-N-100-N2G-040FF1 is a compact synchronous motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed to be driven by digital controllers, it supplies tightly regulated rotary motion to light servo axes used in semiconductor handlers, laboratory pipetting stations, and small packaging modules. The motor’s physical format supports installations where fast acceleration and minimal footprint are required while still delivering the dynamic behavior needed for precision automation. Its compact layout also makes it suitable for small mechanisms where available mounting space is limited and moving mass must be kept low.
At standstill, the motor can produce 0.60 Nm of continuous torque, which supports holding duty and controlled low-speed motion. During normal operation, it can reach a nominal speed of 10000 rpm, allowing short cycle times in high-throughput equipment. Accurate alignment to mounting plates is aided by a 40 mm centering diameter, and standard balancing helps limit vibration at high speed. Power and feedback conductors exit on the right side through a connecting cable with coupling hardware, which simplifies routing in compact machine spaces. Position information is returned through resolver feedback, permitting the associated drive to maintain stable speed and torque control even where electrical noise is present. A standard housing encloses the stator, so the motor fits typical machine frames without requiring special external protection.
The integrated blocking brake delivers 1.0 Nm of holding torque to secure vertical or suspended loads when the drive is de-energized. The motor size is 025 and the length code is B, which helps confirm fit within tight mechanical clearances. The rotor is fitted with a plain shaft, and the motor is built without shaft seal, making it suitable for clean, dry enclosures where fluid ingress is not expected. A standard shaft end on side A and the absence of a side B extension simplify coupling to miniature gears or belt pulleys. Because no shaft seal is fitted, the motor is better suited to sheltered installations than to wet or contaminated operating areas.
