MDD025A-N-100-N2G-040PR0
The MDD025A-N-100-N2G-040PR0 is a compact synchronous motor from Bosch Rexroth Indramat in the MDD Synchronous Motors series. It is intended for operation with digital drive controllers, where it converts regulated stator current into rotary motion for light-duty servo axes. This makes the motor suitable for compact positioning tasks such as pick-and-place units, miniature indexing tables, and other assemblies that need quick response in a small installation space. Its compact housing helps it fit into tightly arranged machine sections without requiring a large mounting envelope.
The front flange uses a centering diameter of 40 mm, which helps the motor seat squarely in a matching locating pocket. The motor provides a continuous standstill torque of 0.33 Nm, allowing it to maintain holding force while energized at zero speed. During operation, the rotor can reach 10000 rpm, which supports fast cycle rates in short-travel applications. The cable connection exits on the right side, helping keep the connector path clear where surrounding components limit routing space. A shaft seal is fitted at the output journal to help keep lubricant in place and reduce the entry of dust or coolant into the bearing area.
The rotor uses a standard balance grade, which helps limit vibration on small mounting surfaces and supports smooth running at high speed. Position information is provided through resolver feedback, allowing the drive to monitor rotor angle reliably across the operating range. The motor is supplied without a blocking brake, so any holding function during power-off conditions must be provided by the drive or by external hardware. The size code 025 and length code A keep the housing compact for small-axis layouts. Power is transmitted through a single-ended shaft with a keyway, which allows secure coupling to small pulleys, hubs, or spindle elements.
