MDD025A-N-100-N2G-040GR1
The MDD025A-N-100-N2G-040GR1 is a compact synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is supplied as a motor for digital drive controllers, where tight speed regulation and quick acceleration are required in automated handling or small-scale machining stations. This type of motor is suited to compact axes that need responsive starts, stops, and repeatable motion in limited machine space. The unit translates commanded current into rotary motion during normal operation. An integrated blocking brake secures the load when power is removed.
A centering pilot of 40 mm simplifies concentric mounting and helps the standard-balanced rotor run smoothly at its nominal speed of 10000 rpm. During static positioning, the motor can deliver 0.33 Nm of continuous stall torque, and the brake can apply up to 1.0 Nm to hold the shaft without energizing the windings. Motion feedback is generated by resolver feedback, which returns rotor position and velocity data to the drive in real time. This feedback supports stable speed control and accurate stopping behavior during short indexing moves. A right-side cable exit supports installations that place power and signal leads on the machine's service side.
The electrical interface is a sealed connector that mates directly with the drive harness, and this orientation matches the A length code and the compact 025 frame size. A plain shaft transmits torque to couplings or miniature timing pulleys, and the motor is equipped with a shaft seal to limit lubricant migration along the journal. The motor has a standard front shaft only, leaving side B free for mounting close to gear stages. Its housing encloses the stator windings in a compact form without external cooling fins. That layout helps the motor fit into tight assemblies where surrounding mechanical parts leave little extra clearance.
