MDD025B-N-100-N2G-040FD0
The MDD025B-N-100-N2G-040FD0 is a compact synchronous servomotor produced by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. Intended for pairing with digital drive controllers, this unit supplies finely controlled rotary motion to light-duty axes in pick-and-place modules, printing stations, and small handling arms. The size-025 frame and length code B keep mass and envelope low, while the high nominal speed supports rapid indexing. This type of motor is typically selected for applications that need repeatable starts and stops without giving up compact installation dimensions.
The continuous operating point includes a standstill torque of 0.60 Nm, which indicates the torque the stator can produce continuously without exceeding thermal limits. Rapid cycles are possible because the rotor is rated for a nominal speed of 10000 rpm, allowing high surface velocity while remaining synchronized with the drive frequency. A centering diameter of 40 mm positions the motor concentrically on mounting faces to reduce radial runout. Power, brake, and feedback leads exit on the rear housing toward Side B, and they are arranged for a connecting cable with coupling unit to simplify cable routing in compact cabinets. That combination supports installations where available bend space behind the motor is limited.
The motor uses a plain shaft, which transmits torque without keyways and works well with backlash-free clamping hubs in small gearboxes. Position data is provided by resolver feedback, and the resolver supplies continuous rotor position information for commutation and speed control across the operating range. The motor is supplied without a blocking brake, so any static load holding must be handled by the drive or by external clamping hardware. The front bearing region is delivered without shaft seal, so the mounting area should be kept suitable for an unsealed shaft end and protected from direct contamination or fluid exposure.
