MDD025C-N-100-N2K-040PF1
The MDD025C-N-100-N2K-040PF1 is a compact synchronous motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Delivered as a motor for digital drive controllers, it supplies rapid, regulated rotary motion to axes that require precise velocity and position control in automated handling systems or light machining cells. Its compact format makes it suitable for installations where mounting space is limited, while still supporting the responsive servo behavior needed for short travel moves and repeatable positioning.
The motor seats in a pilot bore with a centering diameter of 40 mm, which helps keep the stator concentric with mating machine parts. Power and feedback connectors exit on the right side, and the factory-installed connecting cable with coupling unit simplifies routing in cramped cabinets or compact assemblies. When stationary but energized, the electromagnetic design can hold a continuous torque of 0.90 Nm, which is useful for keeping light fixtures in place without a separate brake. During motion, it reaches a nominal speed of 10,000 rpm, supporting short cycle times in pick-and-place equipment and small spindle stages.
A blocking brake supplies up to 1.0 Nm of retaining torque after power is removed, helping prevent back-driving on vertical or offset loads. Position data is delivered by an integrated absolute encoder, so the controller can identify shaft angle immediately after startup. The output shaft uses a keyway for positive drive coupling, and a shaft seal helps limit the entry of dust or cutting fluid. Motion feedback to the drive is transmitted through resolver feedback, a format valued for noise immunity at high rotational speeds, while the standard housing, standard dynamic balancing, size 025 frame, length code C, and single-ended shaft keep the motor suited to fast-moving, low-inertia servo axes.
