Product Description:

The MDD025B-N-100-N2G-040GB0 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Intended for use with digital drive controllers, it transforms controlled current from the inverter into rotary motion for precise positioning in compact assembly stations and laboratory handling devices. A 025 frame with the B length code keeps overall mass low, so the motor fits into confined mechanical spaces while still supporting high-speed duty cycles. This combination makes it suitable for small axes where quick response and compact installation are both important.

Mechanical and electrical interfaces are arranged for straightforward cabinet routing. Power and feedback leads exit on Side B, and a keyed connector mates directly with the standard harness. The front flange provides a 40 mm centering pilot for concentric seating against gearboxes or adapter plates. Continuous stall torque is rated at 0.60 Nm, which provides holding force for light tooling and compact positioning tasks. Rated speed reaches 10000 rpm, enabling rapid indexing cycles in test rigs or pick-and-place axes. Because the motor is supplied without a blocking brake, any required static holding torque must be generated by the drive or by external mechanical support. Standard balancing helps reduce residual vibration across the usable speed range, and the shaft end on side A follows the normal series geometry for common coupling arrangements.

Feedback is supplied by integrated resolver feedback, allowing the drive to monitor rotor position during fast accelerations and reversing moves. The motor uses a plain shaft with no keyway, which supports clamp-style couplings that help reduce play in high-speed service. A standard housing encloses the stator and includes a shaft seal that helps block dust and coolant mist. The seal also helps limit lubricant escape when the motor is mounted vertically. The connection-side shaft end is omitted to shorten the rotor and reduce overhang mass, which supports stable running in compact motion assemblies.
