Product Description:

The MDD025A-N-100-N2G-040MC0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a compact motor for digital drive controllers, it provides closed-loop rotary actuation in automated pick-and-place axes and light tooling spindles. By converting electrical commands from the drive into proportional torque, the unit supports precise velocity and position control in factory automation. Its compact format also suits installations where fast response and a short motor body are important.

In continuous duty, the motor supplies 0.33 Nm of torque. During motion, it reaches a rated speed of 10000 rpm, matching high-frequency command signals from the digital controller and supporting rapid rotary movement on small axes. Power and feedback conductors exit on side A, and the machine end uses a connecting cable with a coupling unit for a direct electrical connection. Rotor orientation is tracked by resolver feedback, so the drive can close the position loop even in electrically noisy environments. This feedback method gives the controller the position information needed for stable speed regulation and repeatable motion.

The shaft interface uses a keyway and does not include a side-B shaft extension, which keeps the output arrangement straightforward for coupling to the driven load. A centering collar of 40 mm locates the frame against gearheads or bearing blocks, while the motor's standard housing protects the windings and is used without a shaft seal. The unit is supplied without a blocking brake, so power-off holding must be provided by the drive or by external mechanical means. Size code 025 keeps rotor inertia low for quick acceleration, which helps the motor respond well in small, high-speed servo applications. The short A-length motor body also helps where installation depth is limited.
