Product Description:

The MDD025A-N-100-N2G-040FL0 is a compact synchronous motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it is used when a fast rotary axis must follow finely resolved position commands from a CNC or PLC. The small frame supports dense installation in pick-and-place robots, labeling heads, and miniature process spindles where space and weight are limited. This layout also suits machine sections that need repeatable motion without adding a large motor body.

This model supplies a continuous standstill torque of 0.33 Nm, giving it enough holding force for light loads while limiting thermal rise during static phases. When energized by the drive, the rotor can reach a nominal speed of 10,000 rpm, so rapid indexing and high surface-speed tooling are possible without additional gearing. Mechanical centering is simplified by a 40 mm centering diameter, which aligns the motor housing precisely to the machine plate. Power and feedback cabling exit on the left side, helping keep conductors clear of moving parts when the motor is mounted on right-hand machine walls. Rotor position is returned to the controller through resolver feedback, supporting closed-loop control that remains tolerant of electrical noise and high acceleration rates.

Connection to the drive cabinet is handled through a single connector, which reduces exposed cable interfaces and keeps the motor connection compact. For applications that rely on drive torque or external clamps, the rotor is supplied without a holding brake, which removes the need for brake coil power. The output shaft is a plain shaft with no side-B stub, so couplings or pulleys can seat directly without secondary machining. Its length code A body, standard balancing grade, and unsealed housing keep the overall package short for enclosed, low-contamination machines where minimal mass and high rotational speed are important.
