Product Description:

The MDD025A-N-100-N2K-040GD1 synchronous motor is produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified for use with digital drive controllers, it delivers rapid rotary motion for compact automation axes in assembly, semiconductor, and packaging equipment. The motor’s built-in absolute encoder eliminates the need for external scale hardware by sending precise position data directly to the controller, allowing closed-loop positioning and speed regulation within a small footprint.

Its thermal design supports a continuous standstill torque of 0.33 Nm, so the motor can hold clamped loads without overheating when motion pauses. During operation, the rotor can spin at up to 10,000 rpm, providing the high peripheral velocity demanded by miniature spindles or pick-and-place heads. A machined pilot with a 40 mm centering diameter aligns the housing concentrically to the machine frame, reducing runout. For safety, a spring-applied blocking brake supplies 1.0 Nm of static holding torque whenever power is removed. The output interface is a plain shaft, so couplings or pulleys must rely on frictional locking rather than keyway engagement, which simplifies shaft machining and reduces imbalance at full speed.

Dynamic balance remains within the standard grade to minimize bearing load during high-speed operation. All electrical terminations exit on Side B through a connecting cable with coupling unit, reducing connector count and simplifying cable handling when the motor is installed or removed. Speed information is supplied through resolver feedback to the drive for stable control across the operating range, while a shaft seal and the standard housing help protect internal laminations from coolant. The plain shaft end on side A completes the compact A-length construction and keeps the motor suitable for tightly spaced assemblies.
