Product Description:

The MDD025A-N-100-N2G-040GB0 is a synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed as a motor for digital drive controllers, it supplies tightly regulated torque and speed to compact automation axes. The model combines the small motor size 025 with the short length code A, so it fits in restricted envelopes. Standard housing and standard rotor balancing minimize vibration and simplify mechanical alignment when the unit is installed in gear stages, linear tables, or indexing platforms.

A centering recess of 40 mm provides the mounting interface and helps keep coupling to adjoining machine parts concentric. Power and feedback conductors exit on Side B, and the round Connector termination helps keep cable routing straightforward in crowded panels. At standstill, the motor delivers a continuous torque of 0.33 Nm, providing stable force for holding or slow moves without extra cooling. During dynamic cycles, it reaches a nominal speed of 10000 min⁻¹, so it can drive high-speed pick-and-place heads or miniature spindles. Standard balancing keeps residual unbalance forces low, and the standard housing shields internal laminations from airborne particles during long duty periods.

Position data are returned through resolver feedback, allowing accurate commutation even in electrically noisy environments. Because the motor is supplied without a blocking brake, any static holding function must be managed by the inverter or an external clamp. The output uses a plain shaft fitted with a shaft seal; this arrangement retains lubricant inside coupled gearboxes and helps limit contaminant entry. A standard shaft end is provided only on the drive side, so no secondary shaft projects from side B, which reduces overall length and rotating inertia.
