Product Description:

The MDD025A-N-100-N2K-040MA1 is a compact AC servo unit produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for pairing with digital drive controllers, it delivers high-speed, closed-loop rotation for light conveyors, laboratory actuators, and compact tooling stations that demand quick step-and-settle behavior within tight mechanical envelopes.

The motor supplies a continuous standstill torque of 0.33 Nm and can reach a base speed of 10000 min⁻¹, giving designers a wide mechanical power band without external gearing. A blocking brake rated at 1.0 Nm secures vertical or position-critical axes during power loss, while standard balancing keeps vibration low across the full speed range. The centering diameter is 40 mm, simplifying alignment with precision gearboxes, and the frame follows the compact 025 size code so multiple axes can fit inside crowded machines. Heat is dissipated through the standard housing; there is no shaft seal, so ambient conditions must be clean and dry. An integrated absolute encoder provides single-turn position data directly to the controller for homing-free startups.

Electrical and mounting features complete the profile. Power and feedback conductors exit on Side A, and the single-cable architecture uses a robust connector interface for fast replacement. Rotor angle is resolved through resolver feedback, permitting stable control even under electrical noise. A keyed shaft, identified by the keyway type, transmits torque securely to couplings, and the shaft end is supplied only on the drive side to minimize length. Motor length code A, standard housing, and standard balancing all align with modular assembly lines that favor repeatable dimensions and predictable inertia.
