Product Description:

The MDD090B-N-040-N2M-110PL1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts controlled electrical power into rotary motion that can be regulated in a closed loop. In automated lines, packaging machines, and material-handling axes, the unit provides precise position and velocity control while working with Rexroth inverters through its built-in feedback and brake hardware.

During continuous operation at zero speed, the motor can sustain 7.2 Nm of torque, so holding or low-speed processes can be maintained without overheating. For higher throughput, it reaches a nominal shaft speed of 4000 rpm, which supports synchronous operation at high rotational speed. A blocking holding brake applies 6.5 Nm of countertorque when power is removed, providing secure axis retention. Position data over the full rotational range is generated by an integrated multiturn absolute encoder and transmitted through digital servo feedback, allowing the controller to resume motion without homing. Mechanical alignment to gearboxes or mounting flanges is simplified by a centering pilot of 110 mm, which helps keep the stator concentric with driven components and reduces vibration at speed.

Cabling is straightforward because power and feedback connectors exit on the left side through a sealed connector interface, leaving adjacent panels clear. A shaft seal at the output end limits dust or fluid ingress, and the standard aluminum housing carries external ribs to release motor heat. The compact 090 frame size with B length code places the active core in the mid-range of the series and balances torque density against overall depth. The rotor has standard balancing quality, and the shaft uses a one-ended layout without a side-B extension; its keyway supports positive coupling to pulleys or couplings.
