Product Description:

The MDD025A-N-100-N2G-040FR0 is a compact servo unit in the MDD Synchronous Motors series produced by Bosch Rexroth Indramat. Intended for use with the company’s digital drive controllers, the motor supplies high-speed rotary motion to light indexing tables, small tool spindles, and auxiliary axes where space is restricted and rapid acceleration is required.

This model follows the manufacturer’s standard balancing class to limit vibration, and its centering pilot measures 40 mm for repeatable flange alignment. Mechanical size is identified as 025, while length code A keeps the overall body short for tight cabinets. Power and feedback conductors exit on the right-hand face so wiring stays clear of moving parts; the interface is a keyed connector that permits quick replacement without disturbing adjacent hardware. The housing is the standard, non-ventilated style, suited to conduction cooling through attached machine structures, and there is no shaft seal because the motor is intended for clean, enclosure-rated installations.

Continuous stall torque is rated at 0.33 Nm, giving stable holding force for low-inertia loads, while the rotor can reach a nominal speed of 10000 min⁻¹ for processes that demand high surface velocity. Position and velocity are reported through Resolver feedback, allowing the drive to close current and speed loops even under electrical noise. The single-ended plain shaft simplifies coupling to precision collets, and the design is delivered without a blocking brake, so any static load must be secured by the drive or external locks. A standard shaft end on side A, no side B extension, and the absence of a shaft seal further reduce inertia and simplify maintenance.

Wake Industrial offers same-day shipping on this motor, applies a 1-year warranty to every purchase, and supports a free chat tool for general questions about type codes or fault indicators.
