MDD025A-N-100-N2K-040PA0
The MDD025A-N-100-N2K-040PA0 is a compact synchronous servo motor from Bosch Rexroth Indramat's MDD Synchronous Motors series. Designed for digital drive controllers, it converts drive current into controlled rotary motion for positioning tasks in automated assemblies and small robotics. Its compact housing suits installations that need high speed and low inertia in a limited mounting space. This type of motor is commonly used where accurate speed regulation and repeatable positioning are needed without adding a large mechanical footprint.
The motor develops a continuous standstill torque of 0.33 Nm, allowing stable holding and low-speed feed motion without additional gearing. Under rated excitation, it can reach a nominal shaft speed of 10000 rpm, which supports rapid cycle times in pick-and-place or spindle applications. Position information is derived from an integrated absolute encoder, giving the controller multi-turn data so homing after power loss is not required. Coil position is also tracked through resolver feedback, which provides an analog sine-cosine signal that remains tolerant of electrical noise. Using both feedback methods helps the paired drive maintain stable motion control across startup and normal operation. All power and feedback lines exit on Side A of the frame, which can simplify cable routing when the motor is mounted beside other axes.
Mechanical alignment is handled by a centering pilot of 40 mm, which keeps the motor concentric with the driven element during high-speed operation. Electrical connection uses a sealed connector rather than loose leads, which keeps the interface compact and protected. The shaft uses a keyway for positive torque transmission to pulleys or couplings, and the flange-mounted design includes a shaft seal to help keep lubricants in the bearing cavity while limiting dust or coolant entry. These features support use in compact machinery where secure coupling and protected connections are important for continuous operation.
