MDD025A-N-100-N2G-040ML1
The MDD025A-N-100-N2G-040ML1 belongs to the MDD Synchronous Motors series produced by Bosch Rexroth Indramat. It is a small-frame AC synchronous motor intended for direct pairing with digital drive controllers in automated machinery. By delivering closed-loop speed and torque control, the unit acts as an electromechanical actuator for pick-and-place axes, compact tooling heads, and other high-cycle positioning tasks. Its compact format suits installations where available mounting space is limited but repeatable motion is still required.
This model is optimized for high rotational duty, reaching a nominal speed of 10,000 rpm. At standstill, it can supply 0.33 Nm of continuous torque, permitting fine force modulation during precise positioning. Rotor position information is generated through resolver feedback, which provides continuous angle signals for commutation and speed control. Electrical and signal leads exit on the left side of the housing, making cabinet routing predictable in multi-axis assemblies. Accurate mechanical alignment to a machine plate is aided by a 40 mm centering diameter that fits standard register bores and helps maintain concentricity between the motor and the driven load.
A spring-applied brake inside the rear frame delivers 1.0 Nm of holding torque to secure vertical loads or maintain position during emergency stops. Power transfer occurs through a keyway shaft, which is commonly used for couplings, pulleys, and similar driven elements. Because the motor is supplied without a shaft seal, it should be installed where direct exposure to fluids is not expected or protected by the surrounding machine design. Dynamic operation is supported by standard balancing, which helps limit vibration at full speed and reduces mechanical stress on adjacent components. Additional configuration details include a connector-based power interface, motor size 025, length code A, a single-ended shaft without a side B extension, and a standard ventilated housing that relies on ambient air for heat dissipation.
