Product Description:

The MDD025C-N-100-N2K-040FC1 belongs to the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. This compact motor is intended for digital drive controllers where rapid acceleration and precise positioning are required on lightweight rotary axes in automated assembly and electronic manufacturing lines.

The motor’s rated mechanical performance is defined by a nominal speed of 10000 min⁻¹, allowing high cycle rates with limited travel. At standstill it can deliver 0.90 Nm of continuous torque, which is sufficient to hold or index light loads without overheating. A centering diameter of 40 mm sets the reference for concentric mounting and keeps run-out within tolerance. Power and feedback conductors exit on Side A to simplify cable routing toward the cabinet. Standard dynamic balancing minimizes vibration, and the C-length frame provides additional stack height compared with shorter variants, increasing torque density without enlarging the 025 size envelope. The housing is the standard sealed design typical for the series.

For static holding when power is removed, an integrated blocking brake supplies 1.0 Nm of torque. Position information during motion is returned through Resolver feedback, while fine absolute position at start-up is available from the Integrated absolute encoder. The output shaft is a Plain shaft that mates with friction or clamp couplings; it is delivered without a shaft seal, so external sealing must be arranged if fluid ingress is expected. Electrical connection is accomplished through a Connecting cable with coupling unit, enabling quick replacement without opening terminal strips. Standard housing finish, the absence of a secondary shaft end, and resolver-based feedback make the unit suitable for small gantries, feeders, and pick-units where compact size and deterministic velocity control are essential.
