Product Description:

The MDD025B-N-100-N2G-040FL0 is a brushless AC servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. In automated assembly cells, the device converts drive commands into high-speed rotation on compact linear stages, feeders, and tooling spindles, giving digital controllers direct authority over position and velocity for precision tasks. Its compact format makes it suitable for installations where available space is limited and fast response is required for repeatable motion. The motor is intended for digital drive systems that regulate motion directly at the axis.

A centering pilot of 40 mm aligns the motor to flanges so shaft concentricity is preserved during installation. Electrical power and feedback cables exit on the left side through a keyed connector that simplifies routing in compact machine layouts. During static hold conditions, the rotor can deliver 0.60 Nm of continuous torque, which supports light clamping or index positioning without overheating. Under rated excitation, the rotor reaches a nominal velocity of 10000 rpm, allowing high cycle frequencies in small pick heads or tool drives. Position and velocity are returned to the drive by resolver feedback, which provides analog sine-cosine signals for closed-loop control. The rotor is balanced to a standard quality grade, and the plain shaft accepts couplings without key slots to help reduce vibration.

The motor uses a standard housing matched to the compact 025 frame size and the intermediate B length code, which helps keep mounting depth low inside tight machines. The motor is supplied without a blocking brake, so axes that must remain fixed at standstill need external clamping or servo locking from the drive. The shaft end has no side-B extension, and the lack of a shaft seal suits clean, dry process zones where extra ingress protection is not required. Its designation as a motor for digital drive controllers supports direct use with compatible Rexroth control systems.
