MDD025A-N-100-N2K-040FB0
The MDD025A-N-100-N2K-040FB0 is a compact synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into rotary motion for precise position and velocity control in automated assembly, testing, and packaging lines. Its small frame supports direct mounting in confined machinery where installation space is limited. The motor is also suited to compact indexing units and light handling axes that benefit from low moving mass and quick response.
Its mechanical interface uses a centering diameter of 40 mm, which helps align the motor accurately on gearboxes or flange plates. Power and feedback cables exit on Side B through a keyed connector, which helps keep cable routing orderly in tight machine layouts. At standstill, the rotor can deliver 0.33 Nm of continuous torque, making it suitable for light-duty holding and controlled low-speed motion. Position data is generated by an integrated absolute encoder, so the controller can identify shaft angle immediately after power is applied. Standard dynamic balancing helps reduce vibration during operation and supports smooth rotation at elevated speeds.
For applications that rely on regenerative braking or external clamping, the motor is supplied without a blocking brake, so no brake drag is introduced when the axis is released. The construction follows length code A and size 025, resulting in a short motor body that helps reduce inertia and fit densely packed axis groups. During operation, it can reach a shaft speed of 10000 min⁻¹, allowing high surface speeds for small tools and compact spindles. The plain shaft and the lack of a shaft seal keep the mechanical layout simple for clean, enclosed installations. This arrangement is appropriate for systems where holding force is provided by the drive or by external machine hardware.
