Product Description:
The MDD025A-N-100-N2G-040PA0 is a brushless AC servo unit built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed to pair with digital drive controllers, the motor converts electrical input from a pulse-width-modulated inverter into controlled rotary motion for indexers, small gantry axes, and high-speed tooling spindles. Its compact form factor and standard housing allow tight installation inside machines while maintaining the stiffness needed for accurate motion during rapid duty cycles.
The motor’s mechanical interface starts with a centering pilot of 40 mm, giving a repeatable datum for flange mounting. Power and sensor leads exit on the drive end because the connections are on Side A, and a single circular connector accommodates both phases and feedback conductors to simplify cable routing. Under continuous stall conditions, the electromagnetic package develops 0.33 Nm of torque, and when released from stall it can reach a rated speed of 10,000 rpm, making it suitable for light, high-speed positioning tasks. Standard dynamic balancing minimizes residual forces at this speed, while the A length code indicates the shortest stator stack so thermal mass and inertia stay low for fast acceleration.
Motion control precision is aided by resolver feedback, which returns absolute rotor angle to the drive for real-time current modulation. The shaft is machined with a keyway to support positive-drive couplings, and a shaft seal protects the internal bearings from coolant spray or dust. Frame size 025 limits the overall diameter, and the shaft terminates only on the front side, leaving the rear free of an auxiliary shaft end. The motor is supplied without a blocking brake, so any static holding force must be provided by the drive or external locks.
