Product Description:

The MDD025B-N-100-N2G-040GA0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it provides position and velocity control in automated assembly stations, electronic packaging lines, and light handling systems. Its narrow frame and high speed allow rapid rotary axes in compact machine layouts where installation space is limited. Resolver-based feedback and standardized mounting features support stable integration with compatible Rexroth drive modules already used on the machine.

At a continuous standstill torque of 0.60 Nm, the rotor can hold a load without drift while staying within thermal limits. During motion, the motor reaches a nominal speed of 10000 rpm, enabling fast indexing in short-stroke cycles. The flange centering pilot measures 40 mm, which helps provide precise concentric alignment on gearboxes or mounting plates. A plain shaft transmits torque directly, and the motor is supplied with a shaft seal to help limit lubricant migration and airborne contamination. Power and feedback conductors exit on side A through a single connector, which keeps wiring compact in tight enclosures. Position information is generated by resolver feedback, so the drive can maintain commutation and speed control even where electrical noise is present.

Standard balancing reduces vibration at high speed, and the housing uses the standard form factor for this motor line. The motor belongs to size code 025 and length code B, giving a compact stack length that fits lightweight gantry heads and other small moving axes. Its shaft end uses the standard single-ended arrangement without a side-B extension, which keeps the opposite bearing area less crowded. The unit is delivered without a blocking brake, so holding torque must be provided by the drive or by external mechanics when power is removed.
