Product Description:

The MDD025C-N-100-N2K-040MD1 belongs to the MDD Synchronous Motors series produced by Bosch Rexroth Indramat. It is a brushless AC servo motor intended for use with digital drive controllers where precise speed and position regulation are required. In automated assembly stations, pick-and-place axes, or compact spindle drives, the motor converts electrical energy from the drive into regulated mechanical rotation that can be tightly coordinated with the host control system.

The motor reaches a nominal speed of 10000 min⁻¹, allowing short cycle times on light-duty axes. At standstill it can supply 0.90 Nm continuously, so holding torque is available without overheating when a load remains stationary. A blocking brake is integrated and delivers 1.0 Nm of holding capacity, ensuring position retention during power loss or emergency stop. The flange has a centering diameter of 40 mm, establishing radial alignment with gearboxes or machine plates. Closed-loop regulation is based on resolver feedback, which transmits absolute rotor position and speed data to the drive with high noise immunity.

An integrated absolute encoder is included in addition to the resolver, enabling the controller to recover true shaft angle immediately after start-up without homing moves. All electrical terminations exit on Side B, so the cable bundle can be directed away from moving elements. Connection is made through a factory-installed connecting cable with coupling unit, reducing installation time and simplifying service replacement. Power is delivered through a keyway shaft that prevents slippage under reversing torque, and the design omits a shaft seal to minimize friction in high-speed operation while relying on enclosure sealing for contamination control.
