MDD025B-N-100-N2K-040MC0
The MDD025B-N-100-N2K-040MC0 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat and included in the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts controlled electrical input from an inverter into precise rotary motion for high-speed positioning tasks in automated machinery and electronics assembly lines. Its compact format suits installations where mounting space is limited and rapid spindle or tool rotation is required. The motor is intended for enclosed machine areas where accurate motion control and quick dynamic response are more important than high continuous torque.
At its nominal operating point, the rotor can reach 10,000 rpm, a speed that suits small load inertias while helping maintain stable thermal behavior. Continuous torque at standstill is 0.60 Nm, providing holding force for index tables or miniature actuators without oversizing the drive. The flange has a centering diameter of 40 mm, so the motor can be aligned accurately during installation. Position data is supplied by an integrated absolute encoder, allowing the controller to recover the shaft angle immediately after power-up. Power and feedback conductors exit on Side A through a connecting cable with coupling unit, which simplifies removal and helps preserve shielding continuity.
The mechanical arrangement follows standard balancing, which helps keep residual vibration low during high-speed operation. Because it is supplied without a blocking brake, any load-holding function must be provided by the drive or by an external clamp. Feedback remains available across the operating range for accurate speed and position control. The single-ended shaft uses a keyway to transmit torque to pulleys or miniature gear sets, while the opposite side remains closed to suit tight machine frames. The housing is made of standard aluminum and ships without a shaft seal, making it suitable for dry, clean enclosures where no fluid ingress is expected.
