MDD025C-N-100-N2G-040MR0
The MDD025C-N-100-N2G-040MR0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Configured for integration with digital drive controllers, this product serves as the electromechanical link between electronic control loops and mechanical loads. It delivers precise rotary motion for compact assembly cells, labeling stations, and semiconductor handlers where high speed and repeatability are required even when installation space is limited.
In continuous operation, the motor attains a nominal velocity of 10000 rpm, enabling short cycle times without mechanical gearing. While held at zero speed, it can generate a steady torque of 0.90 Nm, providing adequate stall force for light work-holding fixtures. The motor uses standard balancing, and the 40 mm centering diameter ensures accurate pilot seating on mounting flanges. The mechanical power and feedback leads emerge on the right side, so conductors can be bundled along a single edge. A circular connector consolidates motor phases, protective earth, and sensor lines, and the built-in resolver furnishes resolver feedback to the drive, giving rotor position data even during rapid reversals.
Physical dimensions follow the 025 frame, and the axial stack corresponds to length code C, allowing the unit to fit beside parallel axes without collision. A standard aluminum housing dissipates heat, while the design is delivered without a shaft seal, restricting use to dry, dust-free areas. The single output shaft uses a keyway for torque transmission and omits an extension on the non-drive end to shorten the overall footprint. Because the motor is supplied without a blocking brake, vertical applications must use external clamping or rely on drive torque to maintain position during power loss.
