Product Description:

The MDD025C-N-100-N2G-040GR0 is a compact synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers where precise rotary motion must be delivered in confined spaces. By converting electrical energy into controlled torque and speed, the motor acts as the primary actuator in pick-and-place modules, small spindle drives, and other automated stations that demand rapid acceleration and repeatable positioning. That role makes it suitable for axes that need short settling times and steady speed control over repeated cycles. Its compact layout also suits installations where nearby tooling, guards, or cable carriers leave little room for a larger motor body.

The mechanical interface begins with a centering diameter of 40 mm, allowing quick, concentric seating in standard adapter flanges so runout remains low during high-speed operation. Power and feedback lines exit on the right side, which can simplify cable routing when the motor is mounted close to cabinet walls or machine panels. A sealed circular connector carries both motor phases and sensor conductors, avoiding permanent hard-wired terminations at the housing. The combined power and feedback connection also reduces the number of separate cable entry points around the motor body. At standstill, the motor can supply 0.90 Nm of continuous torque, which is suitable for light loads during dwell periods. Because it is supplied without a blocking brake, any static load must be supported by drive torque or an external locking mechanism.

Dynamic characteristics are monitored through resolver feedback, which returns rotor position to the controller with strong noise immunity in electrically active machine environments. Operating at a nominal speed of 10000 rpm, the rotor can follow high-frequency command profiles common in electronic assembly equipment and compact spindle tasks. The motor uses a plain shaft, which mates directly to clamp couplings and avoids keyway-related backlash. A design with a shaft seal helps keep lubricant inside the bearing chamber and reduces the entry of dust from ventilated enclosures. This shaft arrangement supports direct coupling in applications where compact drivetrain geometry matters as much as speed response.
