MDD025B-N-100-N2K-040GA0
The MDD025B-N-100-N2K-040GA0 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it links directly to transistorized inverters to translate torque commands into precise high-speed rotation. The unit is used in automated assembly stations, electronics handlers, and other applications that need fast acceleration in confined spaces. Its compact format suits installations where axis spacing is limited and fast response is required. That operating style also fits short indexing moves and rapid speed changes in automated equipment.
This model’s centering pilot measures 40 mm, allowing repeatable mounting against gearbox or flange faces. Standard balancing keeps vibration within limits at its nominal speed of 10000 rpm. A continuous standstill torque of 0.60 Nm lets the drive hold light loads without overheating, and the plain shaft uses the series’ standard shaft end so external couplings slide on without keyways. The shaft arrangement also supports direct coupling where a keyed connection is not required. Power and feedback leads exit on side A, and the plug-in connector interface keeps connections compact. This arrangement helps maintain predictable cable routing near the motor face. The housing follows motor size 025 with length code B, which keeps the body short and helps reduce inertia.
The motor uses an integrated absolute encoder for single-turn position data. A separate resolver feedback channel provides rotor angle for commutation, giving the drive another source of motion feedback. This feedback combination supports closed-loop motion control during both positioning and continuous rotation. The motor is built without a blocking brake, so stationary holding torque must come from the drive or external mechanics. The front end is supplied with a shaft seal to help prevent lubricant ingress.
