Product Description:

The MDD025A-N-100-N2K-040ML1 is a compact synchronous servo motor from the MDD Synchronous Motors series by Bosch Rexroth Indramat. It is intended for use with digital drive controllers and converts commanded current into precise rotary motion for positioning stages, pick-and-place heads, and other automation axes. Its compact format suits applications that need accurate motion in limited installation space. Its synchronous design also supports stable speed control and repeatable positioning during short, rapid move sequences.

In operation, the motor reaches a nominal speed of 10000 rpm, permitting high-cycle positioning tasks without gear reduction. At standstill, it can deliver 0.33 Nm of continuous torque, so heat rise stays within class F limits during static holding duties. The integrated blocking brake adds short-term retention with 1.0 Nm of brake torque when the drive is not energized. Rotor position is reported through an integrated absolute encoder for single-turn data and separate Resolver feedback for analog commutation signals. This combination lets the drive track shaft position while maintaining smooth current commutation during motion. Power and feedback conductors exit on the left side, which can simplify cable routing when the motor face is oriented toward the operator.

The centering pilot is 40 mm in diameter, providing a repeatable reference when the standard housing is clamped to a mounting flange. Torque is transmitted through a shaft with a keyway, and the shaft end is provided only on side A to avoid unnecessary overhang. Because the motor is assembled without a shaft seal, it is better suited to dry installation areas or to machines that use external guarding against coolant spray. The housing and dynamic balancing are both standard, which keeps the motor aligned with common mounting and operating practices in the series. The standard circular connector supports quick connection, and the absence of a side B shaft end helps keep overall mass and inertia low.
