Product Description:

The MDD025A-N-100-N2G-040PC1 is a small synchronous servo unit built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts command currents from a drive into precise rotor motion for compact pick-and-place axes, labeling heads, or miniature spindles in industrial automation lines. A resolver mounted on the rotor provides real-time position signals so the drive can close a tight feedback loop and keep the axis synchronized with adjacent stations.

This model reaches a nominal speed of 10000 min⁻¹, allowing high-cycle positioning tasks with short move times. At standstill, it can hold a continuous torque of 0.33 Nm; this value marks the thermal limit for static clamping or low-speed creep. A blocking brake is integrated and delivers 1.0 Nm of holding torque to secure vertical loads when power is removed. Mechanical alignment during installation uses a centering diameter of 40 mm, and power plus feedback conductors leave the housing through a connecting cable with coupling unit, simplifying quick exchange in modular machines. Rotor position is measured through resolver feedback, which withstands shock and temperature better than optical encoders in compact frames.

The electrical lines enter on the Side A face, so cabinet layouts can follow predictable conduit runs and strain-relief points. A single-ended shaft with a keyway mates to miniature pulleys or gear sets, while the shaft seal helps prevent lubricant egress into the motor housing. The frame follows size code 025, and its standard balancing lets the rotor run smoothly without extra trimming. Overall geometry matches length code A, and the shaft end is only on the drive side, leaving the non-drive face free for brake and feedback components.
