Product Description:

The MDD025C-N-100-N2K-040GA0 is a synchronous servo motor engineered by Bosch Rexroth Indramat for use with digital drive controllers and belongs to the MDD Synchronous Motors series. As a compact 025-frame unit, it delivers high-speed rotation for pick-and-place modules, textile spindles, and other rapid-cycle axes in automated machinery. The motor converts electrical energy from the drive into mechanical motion with tight velocity and position control, supporting precise, repeatable operation across demanding industrial processes.

At its nominal speed of 10000 min⁻¹, the rotor can complete ten thousand revolutions per minute, enabling fast travel rates where cycle time is critical. The continuous standstill torque of 0.90 Nm defines the constant load the stator can hold without exceeding thermal limits when the shaft is motionless. A centering diameter of 40 mm provides the reference surface that aligns the motor in a machine frame and maintains concentricity. Electrical and feedback terminations exit on Side A, so cable routing is confined to one face of the housing. Power and signal are coupled through a sealed Connector, allowing quick installation and removal during maintenance.

To complement the speed and torque capabilities noted above, the motor uses resolver feedback to transmit real-time rotor position back to the controller with noise immunity suitable for harsh environments. An integrated absolute encoder is mounted on the same shaft, giving immediate multi-turn position information after power-up, which shortens calibration routines. For applications that employ external dynamic braking or rely on drive torque for holding, the unit is supplied without a blocking brake, eliminating unnecessary mass on the shaft. A plain shaft with an internal shaft seal minimizes leakage while allowing direct coupling to precision gearheads or belt pulleys, and the standard balancing grade keeps vibration within acceptable limits.
