Product Description:

Bosch Rexroth Indramat manufactures the MDD025A-N-100-N2K-040PA1 servo motor as part of the MDD Synchronous Motors series. Designed as a motor for digital drive controllers, it converts drive output into precise rotary motion for compact positioning axes, pick-and-place heads, or light transfer stations on automated lines. Its small 025 frame and A-length housing allow integration in tight mechanical envelopes, while the internal balancing and standard housing finish suit general-purpose industrial environments.

A centering diameter of 40 mm aligns the front bearing flange with the mounting face and helps prevent radial misplacement. At standstill, the electromagnetic system can deliver 0.33 Nm of continuous torque, which is enough to hold light loads without overheating during static dwell times. During motion, the rotor reaches a nominal speed of 10000 rpm, matching high-speed spindles or indexing tables that require short cycle times. For safety-related stops, the built-in blocking brake provides 1.0 Nm of static torque when power is removed. Power is transmitted through a shaft with a keyway, so couplings can lock axially without relying only on friction. There is no side B shaft end to interfere with close-coupled gear stages.

Motor power and sensor conductors exit on Side A through a single circular connector to minimize cable loops. Position data are returned by Resolver feedback, and commutation information is also supplied by an integrated absolute encoder so the drive can obtain an angle reference immediately after power-up. A factory-installed shaft seal guards the front bearing against splash and fine dust. Standard dynamic balancing keeps vibration within DIN quality class G on the small 025 frame, and the standard housing finish supports general ambient conditions from typical assembly cells to laboratory automation. Length code A keeps the overall depth short for inline mounting behind miniature gearboxes.
