Product Description:

The MDD025C-N-100-N2G-040MA1 belongs to the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. As a motor intended for digital drive controllers, it provides high-speed rotary motion for light automation axes, pick-and-place tools, and other positioning modules where fast acceleration and precise velocity regulation are required. Electrical power and feedback conductors terminate on a single connector, which helps keep wiring compact in small machine layouts.

Under continuous stall conditions, the unit supplies 0.90 Nm of torque, allowing it to hold a load without active cooling while remaining within thermal limits. During normal operation, it can reach a nominal speed of 10000 rpm, which supports rapid-cycle machines with short indexing times. Installation accuracy is helped by a centering diameter of 40 mm, which aligns the stator housing with compatible mounting flanges. When power is removed, a blocking brake produces 1.0 Nm of holding torque to secure the shaft and prevent back-driving. Motion feedback is provided through resolver feedback, which supplies rotor position and speed data to the controller even at high rotational frequencies. The motor is factory balanced to the standard grade, and its standard housing protects the windings while keeping overall mass low. The shaft end is supplied without a secondary extension on side B, which helps the motor fit tight mechanical envelopes. There is no shaft seal, so the mounting arrangement must keep liquids away from the bearing region.

Cables enter on Side A, which lets harnesses run parallel to the motor body instead of around it. Frame size code 025 and length code C indicate the motor's compact size and active length, helping keep inertia low. A keyway machined into the shaft transmits torque to pulleys or couplings without slip and helps maintain angular alignment between the load and the resolver signal.
