Product Description:

Bosch Rexroth Indramat’s MDD025C-N-100-N2K-040FL0 belongs to the MDD Synchronous Motors series and is intended for use with digital drive controllers in compact automation axes. The motor acts as the rotary actuator that converts drive current into mechanical rotation for positioning or velocity-controlled tasks in assembly stations, pick-and-place heads, and small tooling spindles.

The mechanical interface is defined by a centering diameter of 40 mm, allowing precise alignment to gearboxes or flanges, while the connection hardware is oriented to the Left side so cabling can exit parallel to neighboring devices. At standstill the rotor can deliver 0.90 Nm of continuous torque, a value that guides thermal sizing of the controller and cooling airflow. Dynamic cycles are supported by a rated speed up to 10000 min⁻¹, enabling high throughput where short move times are required. An integrated absolute encoder supplies single-turn position data, eliminating the need for external homing sensors and allowing the servo loop to maintain accuracy immediately after power-up. The rotor is balanced to the standard grade, reducing vibration at this high speed, and the motor’s 025 frame size matches layouts where envelope constraints are strict.

System integration features complete the specification set. Feedback to the drive can also be taken from a resolver feedback channel when an application prefers analog angle information. The unit is shipped without a blocking brake, so holding torque must be provided by the drive or external mechanics during power-off states. Because it is delivered without a shaft seal, the plain shaft design targets clean, dry environments, and the standard housing offers convection cooling surfaces. The C-length rotor stack, identified by the C code, extends continuous torque beyond shorter variants while still fitting inside the single-cable connector arrangement on the housing. A standard shaft end on side A and the absence of a side B extension simplify coupling to miniature pulleys or direct-drive loads.
