MDD025A-N-100-N2G-040PD1
The MDD025A-N-100-N2G-040PD1 synchronous motor is manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Intended for digital drive controllers, the unit turns electrical commands into tightly regulated rotary motion for small pick-and-place axes, inspection spindles, and semiconductor handling stages. Its frame size 025 and short motor length code A reduce inertia, which helps the rotor respond quickly in short-cycle applications. A standard housing and standard balancing help the motor run smoothly, and the motor has a standard shaft end on the drive side with no shaft extension on side B to conserve space inside compact machine envelopes.
At a nominal speed of 10000 rpm, the rotor supports the high cycle frequencies required by modern automation. A continuous standstill torque of 0.33 Nm permits load holding without thermal overload during dwell periods. All power and feedback conductors exit on side B through a connecting cable with a coupling unit, which simplifies cable removal and keeps the front of the motor clear. Precise mechanical alignment is aided by a centering diameter of 40 mm, allowing the stator flange to seat concentrically against mounting fixtures and helping keep radial runout low during rapid indexing.
The integrated blocking brake supplies 1.0 Nm of static torque, preventing vertical loads from drifting when power is off. Torque is delivered through a shaft with a keyway, which provides positive drive for miniature pulleys or gear wheels and supports repeatable torque transfer. Position data are returned through resolver feedback, giving rotor angle information without relying on an optical encoder and helping the system tolerate vibration. A dedicated shaft seal shields the front bearing from coolant splash and airborne debris, which helps extend service life when the motor is installed in open machine frames.
