Product Description:
The MDD025B-N-100-N2G-040PR1 synchronous servo motor is produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for use with digital drive controllers, the unit translates regulated three-phase current into controlled rotary motion for tooling, conveyors, and light pick-and-place mechanisms in industrial automation. Its compact housing supports installation in densely packed assemblies where short travel distances and rapid direction changes are common. The motor is intended for precise motion tasks that require stable speed control, accurate commutation, and repeatable positioning over frequent start-stop cycles.
At standstill the motor can supply 0.60 Nm of continuous torque, which supports prolonged holding duty within its thermal limits. Under full command from the inverter, the rotor reaches 10,000 rpm, allowing rapid indexing in short-cycle processes. A spring-applied blocking brake rated at 1.0 Nm locks the shaft when power is removed, helping hold vertical or suspended loads. Position feedback is provided by resolver feedback, so the drive can monitor rotor angle for commutation and speed regulation during operation. A centering boss of 40 mm helps align the flange accurately with gearheads or pulleys and supports consistent shaft-to-load positioning.
The motor uses frame size 025 with length code B, giving it a slim package for clustered multi-axis mounts. Power and sensor leads exit on the right side through a single keyed connector, which helps keep wiring organized in compact spaces and reduces the chance of misalignment during installation. An integral shaft seal protects the front bearing from coolant spray, and the drive end uses a keyway so torque can be transmitted reliably to a coupling without depending only on friction. The housing is made of standard cast aluminum, and the rotor-shaft assembly is balanced to the standard grade to help limit vibration during high-speed operation. The rear face remains closed because the motor is supplied without a side-B shaft extension, which shortens the overall length and leaves the back of the unit free of a rotating shaft end.
