MDD025A-N-100-N2G-040FF1
The MDD025A-N-100-N2G-040FF1 is a compact synchronous servo unit manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Built for integration with digital drive controllers, the motor supplies fast, repeatable rotary motion that underpins index tables, lightweight actuators, and similar automation axes on factory floors. The 25-frame construction and lightweight rotor allow the device to fit into constrained mechanical envelopes while still delivering the cycle rates demanded by modern assembly equipment.
At its rated operating point, the rotor reaches a nominal speed of 10000 rpm, favoring short move times in high-throughput machinery. Continuous torque at standstill is 0.33 Nm, which is available for holding or low-speed creep. For emergency stops or vertical axes, a blocking brake is fitted that delivers 1.0 Nm of locking torque once power is removed. Position feedback is handled by resolver feedback, which gives analog angle information to the controller. The 40 mm centering diameter aids coaxial mounting, and the rotor is balanced to a standard grade to limit vibration.
All service connections exit on the right side, and power is supplied through a connecting cable with a coupling unit, which supports orderly cable routing and simple connection. The motor follows size code 025 with length code A, so the housing remains short while still enclosing the standard stator and rotor laminations. A plain shaft end is provided on side A only, and the opposite side is left blank. The assembly is delivered without a shaft seal, so it must be installed in dry locations or paired with an external seal if contamination is expected. A standard housing and the plain-shaft design reduce mass and inertia while still permitting accurate torque transmission in digital servo loops.
