MDD025B-N-100-N2G-040MB1
The MDD025B-N-100-N2G-040MB1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it supplies precise rotary motion to compact axes in automated assembly and handling equipment. When paired with an inverter, the unit converts commanded current into proportional torque, allowing closed-loop speed and position control in pick-and-place stations, small gantries, and other industrial automation tasks. Its compact format also suits installations where low moving mass and short response times are important.
At its rated point, the motor delivers a continuous standstill torque of 0.60 Nm, which helps keep indexing tables stationary without overheating. The electromagnetic design supports a nominal speed of 10,000 rpm, enabling short cycle times in high-throughput lines. An integrated blocking brake supplies 1.0 Nm of holding torque, which helps secure vertical loads when power is removed. Accurate mounting is aided by a flange centering diameter of 40 mm, and all power and feedback conductors exit on Side B through a single connector, simplifying cable routing. The motor uses size 025 with length code B in a standard housing, and it has a single shaft end without a secondary extension.
Position data is supplied through resolver feedback, allowing the drive to track rotor position continuously for stable speed and position control. The ground shaft is machined with a keyway so pulleys or couplings can transmit torque without slip during repeated start-stop motion. For installations that provide external sealing or lubrication, the motor is built without a shaft seal, which reduces friction at elevated speed. Rotor balance follows standard balancing, helping the motor run smoothly when mounted on compact machine frames. This arrangement suits dry, enclosed equipment where compact packaging and responsive motion are more important than integrated sealing features.
