Product Description:

The MDD025C-N-100-N2G-040FD1 is a brushless AC servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor designed for digital drive controllers, it serves as the actuator in closed-loop positioning axes where high speed and low inertia are required.

At standstill the motor can generate 0.90 Nm of continuous torque, while the integrated blocking brake supplies 1.0 Nm to secure the load when power is removed. The rotor is dynamically balanced to the standard grade, and the stator housing also follows the standard enclosure configuration, helping keep overall dimensions within the 025 frame size and the C length code. A rated speed of 10000 min⁻¹ allows rapid cycle movements in pick-and-place or spindle applications. Mechanical interface accuracy is supported by a centering pilot of 40 mm, and all power and feedback conductors exit on Side B, simplifying cabinet routing when the motor is mounted with the shaft facing the operator.

Position data are returned through resolver feedback, giving the drive real-time rotor angle and speed information for commutation. The motor uses a connecting cable with coupling unit so electrical disconnection can be performed without opening the motor terminal area. Its plain output shaft follows the standard end specification and omits an additional side B extension; the running surface is therefore a plain shaft that can be coupled directly to a hub or collet. No lip seal is fitted, so the front bearing area is classified without shaft seal, a detail that limits use to clean, dry zones or requires external sealing. Together these features complete the motion package for compact, high-speed axes.
