Product Description:

The MDD025A-N-100-N2G-040MD1 synchronous motor is produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It serves as a motor for digital drive controllers, providing precise torque and high-speed rotation in compact machinery across packaging and electronics lines.

At standstill the winding generates a continuous torque of 0.33 Nm, enabling stable holding force without excess current draw in low-load axes. The motor reaches a nominal speed of 10000 min⁻¹, so drive systems can achieve short cycle times when coupled to small gear sets or direct drive screws. A built-in blocking brake supplies 1.0 Nm of holding torque, allowing vertical loads to remain stationary after power is removed. Electrical connections exit on the rear of the stator because the connection orientation is Side B, which simplifies cable routing in packed panels. Accurate mechanical centering is supported by a pilot diameter of 40 mm that aligns the flange to the machine frame.

Feedback to the controller is furnished through a resolver feedback device, giving absolute rotor position for current-vector formation even during high acceleration. Power is transmitted through a shaft machined with a keyway; the end is standard on the drive side only, with no extension on side B, which keeps mass low. Because the motor is supplied without a shaft seal, installers must ensure the mounting zone is free of coolant spray. Rotor balancing is classified as standard to minimize vibration within the 025 frame. The electrical interface relies on a connecting cable with coupling unit, aligning with the motor’s compact Length Code A, Size 025 frame, and standard housing.
