Product Description:

The MDD090C-N-020-N2L-110GR1 is a synchronous AC servo motor produced by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it is installed in automated axes that need precise torque regulation and position feedback. The model uses motor size 090 with length code C, and its plain shaft is delivered without a secondary shaft end, allowing straightforward coupling to gearboxes or pulleys. Standard housing and standard balancing keep vibration levels predictable during closed-loop motion tasks, which supports stable and repeatable machine movement.

This motor develops a continuous standstill torque of 10.4 Nm, giving machines a stable low-speed holding force without exceeding thermal limits. When power is removed, an integrated blocking brake supplies an additional 6.5 Nm of static torque to secure vertical or suspended loads. A nominal speed of 2000 rpm supports typical servo applications that require steady operation across a useful speed range. Rotor position data is provided by digital servo feedback (DSF) sensors, which let the drive track motion accurately during acceleration, deceleration, and positioning. The centering diameter is 110 mm, so the flange aligns accurately with mounting surfaces and helps limit radial runout.

Cabling exits the motor on the right side, which can simplify routing when several axes are installed close together. The power and feedback circuits share a keyed connector that helps prevent incorrect mating and keeps the connection point compact. A factory-installed shaft seal keeps lubricant inside the bearing chamber and helps block airborne contaminants from entering the motor. The plain shaft geometry avoids keyway stress concentrations in applications that use clamp couplings. Standard housing corrosion protection and standard balancing support reliable operation when minor ambient vibration or slight alignment variation is present.
