Product Description:

Bosch Rexroth Indramat produces the MDD071C-N-040-N2S-095PL2 within the MDD Synchronous Motors series. It is classified as a motor for digital drive controllers. The unit converts electrical energy from an inverter into rotary motion for positioning and velocity tasks on automated machinery, packaging stations, and material-handling axes where accurate speed control is required.

The unit delivers 6.6 Nm of continuous torque at standstill, allowing it to hold a load without forced rotation. When the drive excites the windings at rated frequency, the rotor reaches a nominal speed of 4000 rpm, allowing direct coupling to fast linear actuators or compact gear stages. Its centering diameter measures 95 mm, so the flange aligns precisely with compatible mounting plates and maintains concentricity during high-speed rotation. Balancing is supplied as standard, reducing residual vibration without additional counterweights. The cable exits on the left side, and the power and feedback conductors connect through a circular connector. This layout supports orderly cable routing in compact machine spaces. Digital servo feedback provides closed-loop position data, and the encoder format is DSF for compatibility with Indramat drives.

For static holding or emergency stops, a blocking brake is integrated; it supplies 6.5 Nm of braking torque and engages automatically when power is removed. The motor length code is C, which indicates a longer stator stack in the 071 frame and adds thermal mass compared with shorter lengths. Contaminant ingress along the shaft is limited by a shaft seal, supporting use where incidental oil mist or coolant splash may be present. Mechanical coupling is straightforward because the shaft is machined with a keyway, so pulleys or couplings can be attached without custom clamping hubs. The housing uses standard non-cooled construction, and the motor remains within the 071 frame size.
