Product Description:

The MDD025A-N-100-N2G-040GE0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified for use with digital drive controllers, it is intended to generate precise rotary motion on compact axes in automated machinery where rapid acceleration and closed-loop control are required. The motor uses the shortest frame length in this size, has a standard housing style, and places its power and feedback connectors on the left side to suit machine layouts that require that cable direction.

This model uses standard dynamic balancing to limit vibration and has a centering diameter of 40 mm for repeatable flange alignment. At standstill, it can deliver a continuous torque of 0.33 Nm, which provides steady holding force for positioning tasks. The rated mechanical speed reaches 10,000 rpm, supporting high-speed pick-and-place or spindle duties when paired with a suitable inverter. Rotor position is monitored through resolver feedback, allowing the drive to maintain accurate commutation even in electrically noisy environments. Because it is supplied without a blocking brake, any required static holding must be handled by the drive or by an external brake module.

Installation uses a factory-terminated connecting cable with a coupling unit, which simplifies electrical hookup and reduces the chance of wiring errors. The rotor transmits torque through a plain shaft that omits keyways to reduce shaft-end stress, and the shaft end is present only on side A while side B remains closed. Size code 025 identifies the small stator diameter, making the motor suitable for tight mechanical envelopes where available mounting space is limited. Contaminant ingress is limited by construction with a shaft seal, helping protect the internal bearings when the motor is installed in enclosures exposed to oil mist or fine dust.
