Product Description:

The MDD025C-N-100-N2K-040PC1 is a compact synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for integration with digital drive controllers, the unit turns electrical power into precisely regulated rotation for automated pick-and-place, indexing, or spindle tasks. Its standard housing conserves space in multi-axis assemblies while the design supports high operating speeds used in modern production cells. By providing repeatable torque output and position data to the controller, it helps maintain consistent cycle times across conveyor sections and small gantry axes.

Mechanical alignment is established through a centering collar of 40 mm, ensuring coaxial seating against planetary gearheads or machine frames. The motor can supply 0.90 Nm of continuous stall torque without exceeding thermal limits, which indicates its allowable static load when the shaft is locked. During normal operation, the rotor reaches a synchronous speed of 10000 rpm, supporting rapid acceleration in light-duty positioning axes. Rotor position is monitored through resolver feedback, and an integrated absolute encoder provides immediate power-on angle information to the drive. Standard dynamic balancing minimizes vibration and helps maintain smooth operation at elevated rotational speeds.

Protection against unintentional motion is supplied by an internal blocking brake that develops 1.0 Nm of holding torque. The physical envelope follows size code 025 with length variant C, producing a low-inertia package for quick reversals. Electrical power and feedback are routed through a connecting cable with coupling unit on side A, which keeps the connection point accessible. Drive torque is transmitted through a keyway shaft profile, and a shaft seal protects the front bearing against coolant splash or dust. The single-ended shaft arrangement on side A, with no shaft end on side B, helps keep the motor short for tight mechanical envelopes.
