Product Description:

The MDD025C-N-100-N2G-040GF1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it converts commanded current into controlled rotary motion for compact automation axes. Typical applications include pick-and-place arms, small spindles, and other mechanisms that need rapid acceleration together with steady speed regulation. This type of motor is commonly used where repeatable starts, stops, and short positioning moves are required in a limited installation space. Its combination of high rated speed and an internal blocking brake supports fast cycle operation while helping the axis hold position during power-off intervals.

The motor produces a continuous standstill torque of 0.90 Nm, giving the axis a predictable torque level during holding or low-speed motion. During normal operation, it can reach a nominal speed of 10000 rpm, which suits high-throughput processes that still require servo accuracy. Mechanical alignment relies on a centering diameter of 40 mm, which fits compact mounting flanges in direct-drive layouts or small gearboxes. A rear-mounted blocking brake supplies 1.0 Nm of holding torque to reduce load drift when power is removed. Rotor position is reported through resolver feedback, allowing sinusoidal commutation and stable velocity control even at very low speeds. The feedback arrangement also supports smooth low-speed behavior during indexing and dwell transitions.

Length code C gives the motor the longest stack within the 025 frame, increasing active magnetic length without enlarging the 54 mm square flange. Electrical power is routed through a connecting cable with a coupling unit that exits to the right, which can simplify cable routing when the drive is mounted below the axis. The rotor uses standard balancing, which helps limit vibration during high-speed operation. A plain shaft with a shaft seal supports direct coupling to pulleys or collets and helps prevent lubricant migration into adjacent machine components. The standard housing protects the internal windings while keeping the overall assembly compact.
