Product Description:

The MDD090C-N-020-N2M-110PA0 is an AC synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for pairing with digital drive controllers, it converts electrical command signals into tightly regulated rotary motion for axes in material-handling equipment, machine tools, and other automated cells. Its closed-loop design supports accurate positioning and stable speed control during repeated production cycles. It is suited to applications that require repeatable acceleration, deceleration, and holding behavior under drive supervision.

The motor delivers a continuous standstill torque of 10.4 Nm, allowing it to hold loads for extended periods without thermal overload. Under rated excitation it reaches a nominal speed of 2000 rpm, which suits medium-speed servo applications. Precise flange alignment is aided by a centering diameter of 110 mm, while standard balancing helps keep vibration controlled during operation. Power and feedback conductors exit on side A through a sealed connector interface that simplifies cable routing. The single-ended shaft uses a shaft seal and has no side B shaft extension, which helps reduce contamination paths. Because the unit is supplied without a blocking brake, any static holding force must come from the drive or an external lock. The housing has a standard finish that supports heat transfer from the motor surface.

Position accuracy is enhanced by the integrated multi-turn absolute encoder, which transmits rotor angle to the controller via digital servo feedback and eliminates homing after power cycles. Within frame size 090 and length code C, the motor offers a compact housing that fits machines with limited installation space. Torque is delivered through a hardened shaft machined with a keyway, providing slip-free coupling to gears or pulleys. This feedback arrangement supports synchronized motion in indexing, transfer, and feed applications. The standard housing layout keeps electrical connections organized and supports straightforward integration into automated production lines.
