MDD025C-N-100-N2K-040ML1
The MDD025C-N-100-N2K-040ML1 is a compact motor for digital drive controllers manufactured by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. It converts electrical energy from the drive into mechanical rotation for light-duty feed axes and pick-and-place modules, while an internal blocking brake keeps the load stationary during power-off states. Standard housing, standard rotor balancing, and a single shaft end simplify integration with closely spaced axes in multi-axis machines. Its compact format also suits applications where short travel moves and low moving mass are important.
A nominal speed of 10000 rpm allows the rotor to reach high surface velocity without gearbox multiplication, which helps reduce drivetrain inertia. Continuous stall torque is 0.90 Nm, indicating the torque the motor can deliver indefinitely when locked for static holding tasks such as indexing tables. For short periods, the blocking brake can supply a holding torque of 1.0 Nm, helping prevent back-driving on vertical loads. Motion feedback is generated by an integrated absolute encoder, while the windings also include a resolver feedback channel for analog velocity loops and improved noise tolerance. This arrangement supports fast positioning and stable control in micro-machining or semiconductor handling lines.
The centering pilot measures 40 mm, which keeps the stator aligned coaxially with adjacent mechanics for repeatable mounting. Power and sensor conductors exit on the left, and a pluggable connector interface simplifies cable attachment in compact installations. Torque is transmitted through a shaft with a keyway, which mates with standard keyed hubs to resist slip during cyclic acceleration. The motor has no shaft seal, so it is best suited to clean, dry interiors. The seal-free arrangement also avoids added friction at the shaft collar and helps keep the motor compact.
