Product Description:

The MDD090C-N-020-N2M-110PA2 is a synchronous AC motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts controlled electrical energy from the drive into mechanical rotation that moves or positions machine axes in automated equipment. The model belongs to motor size 090 and carries length code C, giving it a mid-frame package that fits standard MDD mounting layouts. The housing and balancing are standard, which supports general-purpose industrial use in servo-driven machinery.

The centering diameter of 110 mm aligns the flange precisely to adjacent mechanics, while the power and feedback conductors exit on Side A, allowing cable routing toward the drive cabinet without crossing the motor body. A sealed connector interface carries those conductors and helps preserve the enclosure rating during operation. At standstill, the motor can deliver 10.4 Nm of continuous torque, so low-speed regulation and holding duties can remain within its thermal capability. Position data comes from an integrated multi-turn absolute encoder, and its signals are forwarded as Digital servo feedback (DSF) so the drive receives precise rotor-angle information for closed-loop control. Because the feedback is absolute, the control system can retain position information through power cycles without requiring a fresh reference move.

For dynamic motion, the unit reaches a nominal speed of 2000 rpm. The built-in blocking brake supplies 11.0 Nm of holding torque, allowing the load to be secured when the drive is disabled. A single-ended shaft with a keyway transfers torque to the driven mechanism, and a shaft seal helps keep contaminants away from the bearing area. This shaft arrangement supports positive torque transmission to couplings, pulleys, or gear inputs where slip cannot be tolerated. The standard connection hardware also keeps the motor consistent with common MDD mounting and wiring layouts.
