Product Description:

The MDD090A-N-020-N2L-110PA2 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts drive commands into rotational motion for positioning axes on automated machinery. In servo systems, it serves as the rotary actuator between the drive controller and the machine mechanics, supporting repeatable indexing, feed, and point-to-point motion. The model follows size code 090 and length code A, giving a compact envelope for medium-duty work cells. It is balanced to a standard grade for direct coupling to loads, and its standard housing suits multi-axis system layouts.

The motor develops a continuous standstill torque of 3.7 Nm, which is the steady torque available for holding or slow-speed moves without overheating. Under rated drive excitation, it reaches a nominal speed of 2000 rpm, matching common gearbox ratios in transfer lines. Power and feedback conductors exit on Side A, and the factory-installed connector provides a direct plug-in connection. Position and velocity data are generated by digital servo feedback (DSF), giving the controller high-resolution information for closed-loop control. The rotor includes a blocking brake so motion can be locked when power is off. The motor also uses a single-ended shaft arrangement without a side B shaft end, which keeps overhung mass low.

The brake supplies up to 11.0 Nm of static torque to maintain load position. A centering diameter of 110 mm aligns the flange accurately against planetary gearboxes or mounting plates. Power is transmitted through a keyway shaft, and the output comes with a shaft seal to limit lubricant migration into the motor interior. This flange and shaft layout supports direct mounting to driven components while helping protect internal parts during operation.
