MDD025B-N-100-N2K-040FL1
The MDD025B-N-100-N2K-040FL1 is a synchronous motor manufactured by Bosch Rexroth Indramat for integration with digital drive controllers in the MDD Synchronous Motors series. It serves as the rotary actuator in compact positioning axes and spindle heads where fast cyclic motion and accurate repeatability are required. By converting converter-supplied AC power directly into controlled mechanical rotation, the unit supports high-speed automation tasks while maintaining precise velocity and position control inside enclosed production machinery and other compact machine modules.
The motor reaches a nominal speed of 10000 rpm, allowing rapid indexing in small servo stages. At standstill, it can supply 0.60 Nm of continuous torque, enough to hold light fixtures or small workpieces without overheating. A blocking brake is integrated, and its holding capability is rated at 1.0 Nm, which helps prevent back-driving when power is removed. Mechanical centering on the mounting flange is guided by a 40 mm centering diameter, and the output interface is a plain shaft that accepts friction or collet clamping hubs. Standard dynamic balancing reduces residual vibration, and the housing style together with motor length code B helps keep overall mass low for gantry or robot joints.
An integrated absolute encoder supplies multi-turn position data, while a secondary channel provides resolver feedback for drive commutation, eliminating the need for external sensors. Power and signal conductors exit on the left side through a sealed connector, which helps simplify cable routing in tight cabinets. Because the motor is built without a shaft seal, it is intended for clean, dry zones where fluid ingress is not expected. A standard shaft end without a side-B extension simplifies coupling alignment and leaves the rear of the motor unobstructed. The standard housing finish supports routine industrial use, and motor size 025 keeps the package compact for small-axis layouts.
