Product Description:

The MDD025B-N-100-N2K-040MB1 is a small-frame synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it supplies rotational power to axes that demand high-speed positioning in compact automation stages. The unit pairs with Indramat drives to convert commanded current into precise torque, allowing pick-and-place tables, lightweight gantries, or laboratory equipment to accelerate rapidly and settle accurately within servo loops. Its compact format also suits small mechanisms where quick response and low moving mass are important. This makes it useful on axes that require frequent starts, short indexing moves, and repeatable stop positions during operation.

At standstill, the rotor can supply 0.60 Nm of continuous torque under static conditions. The maximum rated velocity reaches 10000 rpm, giving short travel times in low-inertia mechanisms. Power and feedback conductors exit on side B, which can help route cabling away from moving parts. The flange centers to a 40 mm pilot diameter that aligns the frame to gearbox or load adapters. An integrated absolute encoder delivers one-turn position data to the drive, so startup can occur without a homing cycle.

For holding functions, the integral brake applies 1.0 Nm of static torque, locking the shaft whenever control power is removed. The shaft uses a keyway profile and is supplied without a shaft seal, which is better suited to clean, dry installations than to areas where oil or liquid contamination is expected. Standard dynamic balancing keeps vibration within ISO limits, and connector-style terminals with the standard aluminum housing aid convection without external fans. The motor follows size code 025 and length code B, and it comes without a shaft extension on the non-drive end to keep mass low for miniature linear stages.
