Product Description:

The MDD025A-N-100-N2K-040PA0 is manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for digital drive controllers, this compact size-025 motor with length code A converts drive commands into precise shaft rotation for light automation axes. Standard balancing and a standard housing allow installation without auxiliary vibration dampers, while the single-ended shaft leaves side B closed to save space in densely packed machines. Its compact layout also suits equipment where short motor length is important for tight mechanical clearances.

At the mechanical interface, the motor supplies a continuous standstill torque of 0.33 Nm, which supports load holding while limiting winding temperature rise. Dynamic moves can reach a nominal speed of 10,000 rpm, enabling rapid positioning in pick-and-place units or small spindle applications. Mounting accuracy is aided by a 40 mm centering diameter, and all power and feedback conductors exit on side A through a single connector, which helps keep cable routing compact. The standard balancing grade helps control residual vibration at high speed, and natural convection cooling through the standard housing avoids the need for an external blower.

Position data are generated by an integrated absolute encoder, so the drive can identify rotor position immediately after power-up. A resolver feedback channel supports closed-loop control during operation, giving the controller the information needed for accurate commutation and motion regulation. Environmental ingress is restricted by a shaft seal, and torque transfer to the load is handled by a keyway shaft profile that accepts standard keyed couplings. Because the unit is supplied without a blocking brake, any static holding must be achieved electrically by the drive or mechanically by an external clamp.
