Product Description:

The MDD025A-N-100-N2K-040GL0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for use with digital drive controllers. It belongs to the MDD Synchronous Motors series and serves as the electromechanical actuator in compact axes where fast speed regulation is required. By directly coupling to machine loads, the motor converts the controlled current supplied by the drive into rotary motion suitable for precise industrial automation. This arrangement supports accurate positioning and repeatable speed changes in compact machine assemblies.

With motor size 025 and length code A, the unit maintains standard dynamic balancing to minimize vibration at rated speed. The centering pilot measures 40 mm, giving a consistent reference for flange mounting. Electrical and feedback terminations exit on the left side through a removable connector, simplifying cable runs inside tight cabinets. This cable orientation can help when installation space is limited around the motor body. At standstill, the motor can deliver 0.33 Nm of continuous torque, allowing small tooling loads to remain energized without thermal overload. During motion, the rotor reaches a nominal velocity of 10000 rpm, which suits high-speed spindles and pick-and-place heads that demand short cycle times. A standard aluminum housing dissipates the heat generated at these speeds.

Position information is supplied by an integrated absolute encoder, while commutation and velocity loops rely on internal resolver feedback. There is no integrated brake, so applications that need static holding must secure the load externally. A shaft seal helps protect the output end from coolant or dust ingress, which is useful in enclosed industrial equipment. The rotating element is a plain shaft with no keyway or side-B extension. The single-ended shaft layout leaves space for external couplings and supports compact mounting at the driven side.
